Abstract
Background Common interventions for smoking cessation are based on medical advice and pharmacological aidInformation and communication technologies may be helpful as interventions by themselves or as complementarytools to quit smoking The objective of the study was to determine the use of information and communicationtechnologies (ICTs) in the smoking population attended in primary care and describe the major factors associatedwith its use
Methods Descriptive observational study in 84 health centres in Cataluntildea Aragon and Salamanca We included bysimple random sampling 1725 primary healthcare smokers (any amount of tobacco) aged 18ndash85 Through personalinterview professionals collected Socio-demographic data and variables related with tobacco consumption and ICTsuse were collected through face to face interviews Factors associated with the use of ICTs were analyzed by logisticregression
Results Users of at least one ICT were predominantly male young (18ndash45 years) from most favoured social classesand of higher education Compared with non-ICTs users users declared lower consumption of tobacco youngeronset age and lower nicotine dependence The percentages of use of email text messages and web pages were653 740 and 715 respectively Factors associated with the use of ICTs were age social class educationallevel and nicotine dependence level The factor most closely associated with the use of all three ICTs was agemainly individuals aged 18ndash24
Conclusions The use of ICTs to quit smoking is promising with the technology of mobile phones having a broaderpotential Younger and more educated subjects are good targets for ICTs interventions on smoking cessation

BackgroundTobacco consumption is one of the leading preventablecauses of death worldwide [1] for instance respiratoryand cardiovascular diseases and cancer are three well-established health effects of tobacco consumptionamong both smokers and non-smokers [2] It has been

estimated that in Spain smoking is the health problemthat causes most mortality and morbidity Consequentlyit also originates higher health costs [3] The percentageof daily smokers aged 15 or older in Spain was 240(279 in men and 202 in women) according to thelast national survey conducted in 2011ndash12 [4] A largenumber of Spanish smokers declared their willingness toquit smoking (approximately 70) and 274 have triedit on the past year [3] but merely 3ndash5 of them accom-plished it [356]

Interventions to quit smoking are one of the mostcost-effective methods to improve the health of thepopulation [35-8] It is well accepted that the more in-tensive the intervention the best cessation rates for in-stance whilst a 5 cessation per year is reached withminimum advice a 20 can be achieved with more in-tensive interventions [910] Common interventions tohelp smokers quit are based on medical advice andpharmacological assistance as nicotine replacement ther-apy and bupropion Alternative interventions such ashypnosis acupuncture exercise and opioid agonist haveassisted some people in smoking cessation but there isnot a clear consensus on its efficacy [811]The use of technologies that offers access to informa-
tion via telecommunications (Information and commu-nication technology (ICTs)) is augmenting progressivelymainly internet email and cell phone use in fact we livein a growingly electronic world [12-14] For instanceworldwide use of mobile phones increased by 155 in2010 reaching 78 telephone lines per 100 inhabitantswith a cumulative average growth between 2005 and2010 of 195 Likewise Internet use had a 13 ofgrowth in 2010 exceeding the number of 2044 millionsof users Europe and USA are the two geographical areaswith the largest number of internet users 67 and507 respectively [12] According to The National Ob-servatory for Telecommunications and the InformationSociety in Spain 2011 829 of people aged 15 or olderhad a mobile phone and 663 had accessed internet atleast once [15] If these data are analyzed as develop-ment indicators and especially in the case of internet aspotential tools to change behaviours these technologiescan pose a great influence on health policies (directly orindirectly) [1617]The use of ICTs has been growing in several fields in-
cluding medicine for instance appointments can bescheduled on-line and analytical results or health infor-mation can be consulted on internet ICTs technologyhas also been adopted on lifestyle interventions includingsmoking cessation [38] Recent reviews have analyzed theefficacy of web-based interventions on smoking cessation[1819] although results remain inconclusively [20] Ad-vantages of using ICTs on smoking cessation programs in-clude its wide use time and cost savings (they candiminish visits to the health centre and the possibility tocheck the information or messagesmails at patient orhealth professional convenience) and the possibility tosupply personalized support [21]Some recent systematic reviews that evaluates smok-
ing cesation programs that use computer internet mo-bile phone and other electronic aids conclude theireffectiveness altough small and mainly at long term onsmoking cessation compared to no intervention orstandard counseling [22-24]
Describing the use of ICTs among patients attendingprimary care could help us elucidate the viability of anICT intervention in smoking cessation in primary careFor instance our research group will compare brief ad-vice vs personalized E-mail tracking (TABATIC study)[25] Therefore the aim of the present study is to deter-mine the use of ICT in the smoking population attendedin primary healthcare and to describe the main factorsassociated with its use
MethodsStudy designWe conducted a cross-sectional study to describe the useof ICTs among smokers attended in primary care as wellas the main factors associated with that use The studywas multicentre 195 healthcare professionals (generalpractitioners or nurses) of 84 primary healthcare centresof the Spanish public health system in Cataluntildea Aragoacutenand Salamanca (Spain) participated in the recruitment ofpatients
SubjectsSample size was calculated according to the projectrsquosaim which was to estimate the use of ICTs in smokersattended in primary care Assuming an alpha risk of 005and a beta risk of 020 in a two-sided test and a no-response rate of 20 481 subjects were needed Weconsidered that at least half of the Spanish population in2011 had access to internet and mobile phones [15]From November 2011 to January 2012 individuals aged18ndash75 who answered positively to the question ldquoDo yousmokerdquo (independently of the amount) and signed theconsent form were recruited by random sampling Pa-tients were recruited as they visited the primary careteam and each day the first two subjects that fulfilled theinclusion criteria were invited to participate We askedthe health professionals to recruit participants at leasttwo days per week In case the patient declined to par-ticipate in the study the health professional gatheredage and sex and the reason of the refusal Recruitmentand data collection was performed by the health profes-sional that commonly attends the patientPeople suffering from terminal illnesses severe psychi-
atric disorders addiction to other psychoactive sub-stances or who did not consent to participate in thestudy were excluded Of the 1850 patients that fulfilledthe inclusion criteria 1725 agreed to participate (932)The percentage of participation was similar between menand women in each age stratum (36ndash45 years old p =0913 46ndash65 years old p = 0176 gt65 years old p =0246) except that less men (931 vs 980 p = 0008)accepted to participate among individuals aged 35 andyounger

Study variablesThe following information was obtained by healthcareprofessionals collected through face to face interviewsage sex educational level occupational social class civilstatus ICTs (email text messaging and web pages) avail-ability and use self-declared daily tobacco consumptionin cigarettes per day smoking onset age number of pre-vious attempts (of at least of 24 hours) to quit smokingmaximum abstinence time (in days) pharmacologicaltreatment used on previous attempts (nicotine substi-tutes Bupropion Vareniclina) environmental exposureto smoke from family workmates and friends and nico-tine dependence level measured by the simplified two-question Fagerstroumlm test classified as low medium andhigh [26] Educational level refers to the maximum levelof finalized studies classified into no formal studies pri-mary studies secondary and university Subsequently itwas recoded into lower than secondary and ge secondaryTo assign occupational social class we used the Span-
ish classification which is based on Goldthorpersquos schemewhich was designed to facilitate international comparisons[27] Consequently social class was assigned through thecurrent or last occupation of the patient in cases wherethe subject had not worked through the current or lastoccupation of the head of the household [28] The classifi-cation includes five well-established main social groupsbut was subsequently collapsed into smaller number ofcategories manual (social classes IV-V) and non-manualworkers (the rest) to undertake analysis [27]The information in the use of the three ICTs (E-mail
text messages and web pages) was gather by the follow-ing two questions Do you use electronic mail (or inter-netweb page or sms) Possible answers were lsquoNorsquo orlsquoYesrsquo If the participant responded yes then the inter-viewer asked for the frequency of use possible answerswere lsquoless than once a weekrsquorsquo once a weekrsquo or lsquomorethan once a weekrsquo Consequently the use of the threeICTs was grouped into four categories lsquono usersquo lsquolessthan once a weekrsquo lsquoonce a weekrsquo and lsquomore than once aweekrsquo Subsequently it was recoded into lsquono usersquo andlsquolow frequency of usersquo and lsquomidhigh frequency of usersquoThis study included other variables that are not pre-
sented in this paper
Statistical analysisResults are expressed as mean and standard deviation(SD) for quantitative variables or by frequency distribu-tion for qualitative variables Pearsonrsquos Chi-square test
for independence or homogeneity was applied to assessthe relationship between two categorical variables TheStudentrsquos t-test and ANOVA for independent sampleswere used to analyze associations between dichotomicand continuous normal qualitative variables respect-ively Mann-Whitneyrsquos U and Kruskal-Wallis test wereused to compare dichotomic and continuous variables ifthey did not follow a normal distribution Binary logisticmodels were used to assess the associations betweensociodemographic and tobacco consumption factors andICTs use The level of statistical significance was set at005 and all tests were two-tailed Statistical analyseswere conducted using SPSS version 170 (SPSS Inc Chi-cago IL)
ResultsA total of 1725 smokers participated in the study meanage 455 years (SD 136 years) and 865 (511) were maleCharacteristics of participants are shown in Table 1 Par-ticipants were more likely to be married (635) manualworkers (595) and 525 had completed at least second-ary education Mean age of starting tobacco consumptionwas 172 (SD 45) and the mean number of self-declaredcigarettes smoked per day was 154 (SD 93) Half of theparticipants declared a low dependency on nicotine 745of participants declared previous attempts to quit smok-ing and 766 of those did not use any medication incases where they had used medication a nicotine substi-tute was the most frequently used Patients includedtended to live in a non-smoke-free environment of thosewho had a partner 479 declared living with a partnerthat smoked Of those who were working or studying552 declared having co-workers that smoked 654 ofthe participants declared that their friends lived in a smok-ing environmentWhen comparing non-users of any ICT (n = 269) with
users of at least one ICT (any frequency of use) ICTsusers (n = 1456) tended to be male middleyoung (18 to45 years) non-manual workers and had a higher educa-tional level (all p lt0001) The users of at least one ICTalso reported lower consumption of tobacco had startedusing tobacco at a younger age and a higher percentageof them had lower nicotine dependence tended to livewith partners who smoke and in not smoke-free homesand consumed chronic medication No statistically sig-nificant differences were found neither regarding thenumber of previous attempts to quit smoking nor othersmoking environments (Table 1)Frequency of use of the three ICTs is specified in
Table 2 Self-reported use of E-mail text messaging andweb pages were 653 (498 for high use) 74 (508for high use) and 715 (560 for high use) respect-ively Descriptive analysis showed that more high fre-quency users were women middleyoung (18 to 45)

and individuals with a higher educational level Thoseindividuals from lower social classes tended to declareno use or lower use of E-mail text messaging and internetRegarding tobacco consumption variables the number ofcigarettes smoked per day and nicotine dependence washigher among non users of ICTs Conversely users ofboth low and high frequency declared a lower age of startof tobacco consumptionFinally we analyzed factors affecting ICTs use (Tables 3
4 and 5) by comparing no use vs low frequency of use(OR1) and no use vs midhigh frequency of use (OR2)Binary logistic adjusted analysis showed that age wasthe strongest predictor of E-mail frequency use (for in-dividuals aged 18ndash35 OR1 = 334 CI951397-8025and OR2 = 600 CI95 301-953) Higher social class(OR1 = 161 CI95108-234 and OR2 = 429 CI95311-593) and educational level (OR1 = 222 CI95 156-315 and OR2 = 408 CI95 303-548) were also posi-tively associated to the frequency of use of E-mail Lowdependence to nicotine was associated with a midhighuse of E-mail use (OR2 = 203 CI95 122-338) Furtheradjustments did not materially alter these associationsThese results are consistent with crude analysisAll these factors were also associated to SMS and inter-
net frequency of use except that dependence to nicotinedid not remain statistically significant Conversely womenwere more likely to use SMS (OR1 = 215 CI95 163-285 and OR2 = 305 CI95 240-388)When the frequency of E-mail SMS and internet use
was analyzed separately by age social class and educa-tional level the influence of the other factors was similaras among the whole sample studied (results not shown)for instance the direction of the associations of young
age and higher social class remained analogous and sta-tistically significant in both individuals with high andlow educational level
DiscussionPrincipal findingsBy means of a representative sample of the smokingpopulation attended in the public primary care systemwe have studied the differences among smokers in rela-tion to the use of different ICTs (Internet Email andSMS messages) including among the variables demo-graphic characteristics socioeconomic status and smok-ing profile This study shows that the three studied ICTsare widely used especially among the population under45 women more favoured social class of higher educa-tion level and those with lower consumption It alsoshowed that cigarette consumption had started at ayounger age in ICTs usersOur data show that 844 of smokers use some of the
ICTs studied being the use of Internet sms and E-mailand 715 (560 for high use) 740 (508 for highuse) and 653 (498 for high use) respectively Thefrequency of access to web of our study is comparable tothe general population of Spain in 2012 (708) [15] andto some international studies (655) [1429] Amongsmokers Hunt et al showed that 635 were internetusers [30] Some studies have attempted to characterizethe group of internet users (not only smokers) who areinterested in finding information about smoking onhealth-related web pages but not a clear common pro-file has been found [3132] Weaver and colleagues sug-gested that females white respondents people aged55ndash64 and computer owners were positively associated

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

Interventions to quit smoking are one of the mostcost-effective methods to improve the health of thepopulation [35-8] It is well accepted that the more in-tensive the intervention the best cessation rates for in-stance whilst a 5 cessation per year is reached withminimum advice a 20 can be achieved with more in-tensive interventions [910] Common interventions tohelp smokers quit are based on medical advice andpharmacological assistance as nicotine replacement ther-apy and bupropion Alternative interventions such ashypnosis acupuncture exercise and opioid agonist haveassisted some people in smoking cessation but there isnot a clear consensus on its efficacy [811]The use of technologies that offers access to informa-
tion via telecommunications (Information and commu-nication technology (ICTs)) is augmenting progressivelymainly internet email and cell phone use in fact we livein a growingly electronic world [12-14] For instanceworldwide use of mobile phones increased by 155 in2010 reaching 78 telephone lines per 100 inhabitantswith a cumulative average growth between 2005 and2010 of 195 Likewise Internet use had a 13 ofgrowth in 2010 exceeding the number of 2044 millionsof users Europe and USA are the two geographical areaswith the largest number of internet users 67 and507 respectively [12] According to The National Ob-servatory for Telecommunications and the InformationSociety in Spain 2011 829 of people aged 15 or olderhad a mobile phone and 663 had accessed internet atleast once [15] If these data are analyzed as develop-ment indicators and especially in the case of internet aspotential tools to change behaviours these technologiescan pose a great influence on health policies (directly orindirectly) [1617]The use of ICTs has been growing in several fields in-
cluding medicine for instance appointments can bescheduled on-line and analytical results or health infor-mation can be consulted on internet ICTs technologyhas also been adopted on lifestyle interventions includingsmoking cessation [38] Recent reviews have analyzed theefficacy of web-based interventions on smoking cessation[1819] although results remain inconclusively [20] Ad-vantages of using ICTs on smoking cessation programs in-clude its wide use time and cost savings (they candiminish visits to the health centre and the possibility tocheck the information or messagesmails at patient orhealth professional convenience) and the possibility tosupply personalized support [21]Some recent systematic reviews that evaluates smok-
ing cesation programs that use computer internet mo-bile phone and other electronic aids conclude theireffectiveness altough small and mainly at long term onsmoking cessation compared to no intervention orstandard counseling [22-24]
Describing the use of ICTs among patients attendingprimary care could help us elucidate the viability of anICT intervention in smoking cessation in primary careFor instance our research group will compare brief ad-vice vs personalized E-mail tracking (TABATIC study)[25] Therefore the aim of the present study is to deter-mine the use of ICT in the smoking population attendedin primary healthcare and to describe the main factorsassociated with its use
MethodsStudy designWe conducted a cross-sectional study to describe the useof ICTs among smokers attended in primary care as wellas the main factors associated with that use The studywas multicentre 195 healthcare professionals (generalpractitioners or nurses) of 84 primary healthcare centresof the Spanish public health system in Cataluntildea Aragoacutenand Salamanca (Spain) participated in the recruitment ofpatients
SubjectsSample size was calculated according to the projectrsquosaim which was to estimate the use of ICTs in smokersattended in primary care Assuming an alpha risk of 005and a beta risk of 020 in a two-sided test and a no-response rate of 20 481 subjects were needed Weconsidered that at least half of the Spanish population in2011 had access to internet and mobile phones [15]From November 2011 to January 2012 individuals aged18ndash75 who answered positively to the question ldquoDo yousmokerdquo (independently of the amount) and signed theconsent form were recruited by random sampling Pa-tients were recruited as they visited the primary careteam and each day the first two subjects that fulfilled theinclusion criteria were invited to participate We askedthe health professionals to recruit participants at leasttwo days per week In case the patient declined to par-ticipate in the study the health professional gatheredage and sex and the reason of the refusal Recruitmentand data collection was performed by the health profes-sional that commonly attends the patientPeople suffering from terminal illnesses severe psychi-
atric disorders addiction to other psychoactive sub-stances or who did not consent to participate in thestudy were excluded Of the 1850 patients that fulfilledthe inclusion criteria 1725 agreed to participate (932)The percentage of participation was similar between menand women in each age stratum (36ndash45 years old p =0913 46ndash65 years old p = 0176 gt65 years old p =0246) except that less men (931 vs 980 p = 0008)accepted to participate among individuals aged 35 andyounger

Study variablesThe following information was obtained by healthcareprofessionals collected through face to face interviewsage sex educational level occupational social class civilstatus ICTs (email text messaging and web pages) avail-ability and use self-declared daily tobacco consumptionin cigarettes per day smoking onset age number of pre-vious attempts (of at least of 24 hours) to quit smokingmaximum abstinence time (in days) pharmacologicaltreatment used on previous attempts (nicotine substi-tutes Bupropion Vareniclina) environmental exposureto smoke from family workmates and friends and nico-tine dependence level measured by the simplified two-question Fagerstroumlm test classified as low medium andhigh [26] Educational level refers to the maximum levelof finalized studies classified into no formal studies pri-mary studies secondary and university Subsequently itwas recoded into lower than secondary and ge secondaryTo assign occupational social class we used the Span-
ish classification which is based on Goldthorpersquos schemewhich was designed to facilitate international comparisons[27] Consequently social class was assigned through thecurrent or last occupation of the patient in cases wherethe subject had not worked through the current or lastoccupation of the head of the household [28] The classifi-cation includes five well-established main social groupsbut was subsequently collapsed into smaller number ofcategories manual (social classes IV-V) and non-manualworkers (the rest) to undertake analysis [27]The information in the use of the three ICTs (E-mail
text messages and web pages) was gather by the follow-ing two questions Do you use electronic mail (or inter-netweb page or sms) Possible answers were lsquoNorsquo orlsquoYesrsquo If the participant responded yes then the inter-viewer asked for the frequency of use possible answerswere lsquoless than once a weekrsquorsquo once a weekrsquo or lsquomorethan once a weekrsquo Consequently the use of the threeICTs was grouped into four categories lsquono usersquo lsquolessthan once a weekrsquo lsquoonce a weekrsquo and lsquomore than once aweekrsquo Subsequently it was recoded into lsquono usersquo andlsquolow frequency of usersquo and lsquomidhigh frequency of usersquoThis study included other variables that are not pre-
sented in this paper
Statistical analysisResults are expressed as mean and standard deviation(SD) for quantitative variables or by frequency distribu-tion for qualitative variables Pearsonrsquos Chi-square test
for independence or homogeneity was applied to assessthe relationship between two categorical variables TheStudentrsquos t-test and ANOVA for independent sampleswere used to analyze associations between dichotomicand continuous normal qualitative variables respect-ively Mann-Whitneyrsquos U and Kruskal-Wallis test wereused to compare dichotomic and continuous variables ifthey did not follow a normal distribution Binary logisticmodels were used to assess the associations betweensociodemographic and tobacco consumption factors andICTs use The level of statistical significance was set at005 and all tests were two-tailed Statistical analyseswere conducted using SPSS version 170 (SPSS Inc Chi-cago IL)
ResultsA total of 1725 smokers participated in the study meanage 455 years (SD 136 years) and 865 (511) were maleCharacteristics of participants are shown in Table 1 Par-ticipants were more likely to be married (635) manualworkers (595) and 525 had completed at least second-ary education Mean age of starting tobacco consumptionwas 172 (SD 45) and the mean number of self-declaredcigarettes smoked per day was 154 (SD 93) Half of theparticipants declared a low dependency on nicotine 745of participants declared previous attempts to quit smok-ing and 766 of those did not use any medication incases where they had used medication a nicotine substi-tute was the most frequently used Patients includedtended to live in a non-smoke-free environment of thosewho had a partner 479 declared living with a partnerthat smoked Of those who were working or studying552 declared having co-workers that smoked 654 ofthe participants declared that their friends lived in a smok-ing environmentWhen comparing non-users of any ICT (n = 269) with
users of at least one ICT (any frequency of use) ICTsusers (n = 1456) tended to be male middleyoung (18 to45 years) non-manual workers and had a higher educa-tional level (all p lt0001) The users of at least one ICTalso reported lower consumption of tobacco had startedusing tobacco at a younger age and a higher percentageof them had lower nicotine dependence tended to livewith partners who smoke and in not smoke-free homesand consumed chronic medication No statistically sig-nificant differences were found neither regarding thenumber of previous attempts to quit smoking nor othersmoking environments (Table 1)Frequency of use of the three ICTs is specified in
Table 2 Self-reported use of E-mail text messaging andweb pages were 653 (498 for high use) 74 (508for high use) and 715 (560 for high use) respect-ively Descriptive analysis showed that more high fre-quency users were women middleyoung (18 to 45)

and individuals with a higher educational level Thoseindividuals from lower social classes tended to declareno use or lower use of E-mail text messaging and internetRegarding tobacco consumption variables the number ofcigarettes smoked per day and nicotine dependence washigher among non users of ICTs Conversely users ofboth low and high frequency declared a lower age of startof tobacco consumptionFinally we analyzed factors affecting ICTs use (Tables 3
4 and 5) by comparing no use vs low frequency of use(OR1) and no use vs midhigh frequency of use (OR2)Binary logistic adjusted analysis showed that age wasthe strongest predictor of E-mail frequency use (for in-dividuals aged 18ndash35 OR1 = 334 CI951397-8025and OR2 = 600 CI95 301-953) Higher social class(OR1 = 161 CI95108-234 and OR2 = 429 CI95311-593) and educational level (OR1 = 222 CI95 156-315 and OR2 = 408 CI95 303-548) were also posi-tively associated to the frequency of use of E-mail Lowdependence to nicotine was associated with a midhighuse of E-mail use (OR2 = 203 CI95 122-338) Furtheradjustments did not materially alter these associationsThese results are consistent with crude analysisAll these factors were also associated to SMS and inter-
net frequency of use except that dependence to nicotinedid not remain statistically significant Conversely womenwere more likely to use SMS (OR1 = 215 CI95 163-285 and OR2 = 305 CI95 240-388)When the frequency of E-mail SMS and internet use
was analyzed separately by age social class and educa-tional level the influence of the other factors was similaras among the whole sample studied (results not shown)for instance the direction of the associations of young
age and higher social class remained analogous and sta-tistically significant in both individuals with high andlow educational level
DiscussionPrincipal findingsBy means of a representative sample of the smokingpopulation attended in the public primary care systemwe have studied the differences among smokers in rela-tion to the use of different ICTs (Internet Email andSMS messages) including among the variables demo-graphic characteristics socioeconomic status and smok-ing profile This study shows that the three studied ICTsare widely used especially among the population under45 women more favoured social class of higher educa-tion level and those with lower consumption It alsoshowed that cigarette consumption had started at ayounger age in ICTs usersOur data show that 844 of smokers use some of the
ICTs studied being the use of Internet sms and E-mailand 715 (560 for high use) 740 (508 for highuse) and 653 (498 for high use) respectively Thefrequency of access to web of our study is comparable tothe general population of Spain in 2012 (708) [15] andto some international studies (655) [1429] Amongsmokers Hunt et al showed that 635 were internetusers [30] Some studies have attempted to characterizethe group of internet users (not only smokers) who areinterested in finding information about smoking onhealth-related web pages but not a clear common pro-file has been found [3132] Weaver and colleagues sug-gested that females white respondents people aged55ndash64 and computer owners were positively associated

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

Study variablesThe following information was obtained by healthcareprofessionals collected through face to face interviewsage sex educational level occupational social class civilstatus ICTs (email text messaging and web pages) avail-ability and use self-declared daily tobacco consumptionin cigarettes per day smoking onset age number of pre-vious attempts (of at least of 24 hours) to quit smokingmaximum abstinence time (in days) pharmacologicaltreatment used on previous attempts (nicotine substi-tutes Bupropion Vareniclina) environmental exposureto smoke from family workmates and friends and nico-tine dependence level measured by the simplified two-question Fagerstroumlm test classified as low medium andhigh [26] Educational level refers to the maximum levelof finalized studies classified into no formal studies pri-mary studies secondary and university Subsequently itwas recoded into lower than secondary and ge secondaryTo assign occupational social class we used the Span-
ish classification which is based on Goldthorpersquos schemewhich was designed to facilitate international comparisons[27] Consequently social class was assigned through thecurrent or last occupation of the patient in cases wherethe subject had not worked through the current or lastoccupation of the head of the household [28] The classifi-cation includes five well-established main social groupsbut was subsequently collapsed into smaller number ofcategories manual (social classes IV-V) and non-manualworkers (the rest) to undertake analysis [27]The information in the use of the three ICTs (E-mail
text messages and web pages) was gather by the follow-ing two questions Do you use electronic mail (or inter-netweb page or sms) Possible answers were lsquoNorsquo orlsquoYesrsquo If the participant responded yes then the inter-viewer asked for the frequency of use possible answerswere lsquoless than once a weekrsquorsquo once a weekrsquo or lsquomorethan once a weekrsquo Consequently the use of the threeICTs was grouped into four categories lsquono usersquo lsquolessthan once a weekrsquo lsquoonce a weekrsquo and lsquomore than once aweekrsquo Subsequently it was recoded into lsquono usersquo andlsquolow frequency of usersquo and lsquomidhigh frequency of usersquoThis study included other variables that are not pre-
sented in this paper
Statistical analysisResults are expressed as mean and standard deviation(SD) for quantitative variables or by frequency distribu-tion for qualitative variables Pearsonrsquos Chi-square test
for independence or homogeneity was applied to assessthe relationship between two categorical variables TheStudentrsquos t-test and ANOVA for independent sampleswere used to analyze associations between dichotomicand continuous normal qualitative variables respect-ively Mann-Whitneyrsquos U and Kruskal-Wallis test wereused to compare dichotomic and continuous variables ifthey did not follow a normal distribution Binary logisticmodels were used to assess the associations betweensociodemographic and tobacco consumption factors andICTs use The level of statistical significance was set at005 and all tests were two-tailed Statistical analyseswere conducted using SPSS version 170 (SPSS Inc Chi-cago IL)
ResultsA total of 1725 smokers participated in the study meanage 455 years (SD 136 years) and 865 (511) were maleCharacteristics of participants are shown in Table 1 Par-ticipants were more likely to be married (635) manualworkers (595) and 525 had completed at least second-ary education Mean age of starting tobacco consumptionwas 172 (SD 45) and the mean number of self-declaredcigarettes smoked per day was 154 (SD 93) Half of theparticipants declared a low dependency on nicotine 745of participants declared previous attempts to quit smok-ing and 766 of those did not use any medication incases where they had used medication a nicotine substi-tute was the most frequently used Patients includedtended to live in a non-smoke-free environment of thosewho had a partner 479 declared living with a partnerthat smoked Of those who were working or studying552 declared having co-workers that smoked 654 ofthe participants declared that their friends lived in a smok-ing environmentWhen comparing non-users of any ICT (n = 269) with
users of at least one ICT (any frequency of use) ICTsusers (n = 1456) tended to be male middleyoung (18 to45 years) non-manual workers and had a higher educa-tional level (all p lt0001) The users of at least one ICTalso reported lower consumption of tobacco had startedusing tobacco at a younger age and a higher percentageof them had lower nicotine dependence tended to livewith partners who smoke and in not smoke-free homesand consumed chronic medication No statistically sig-nificant differences were found neither regarding thenumber of previous attempts to quit smoking nor othersmoking environments (Table 1)Frequency of use of the three ICTs is specified in
Table 2 Self-reported use of E-mail text messaging andweb pages were 653 (498 for high use) 74 (508for high use) and 715 (560 for high use) respect-ively Descriptive analysis showed that more high fre-quency users were women middleyoung (18 to 45)

and individuals with a higher educational level Thoseindividuals from lower social classes tended to declareno use or lower use of E-mail text messaging and internetRegarding tobacco consumption variables the number ofcigarettes smoked per day and nicotine dependence washigher among non users of ICTs Conversely users ofboth low and high frequency declared a lower age of startof tobacco consumptionFinally we analyzed factors affecting ICTs use (Tables 3
4 and 5) by comparing no use vs low frequency of use(OR1) and no use vs midhigh frequency of use (OR2)Binary logistic adjusted analysis showed that age wasthe strongest predictor of E-mail frequency use (for in-dividuals aged 18ndash35 OR1 = 334 CI951397-8025and OR2 = 600 CI95 301-953) Higher social class(OR1 = 161 CI95108-234 and OR2 = 429 CI95311-593) and educational level (OR1 = 222 CI95 156-315 and OR2 = 408 CI95 303-548) were also posi-tively associated to the frequency of use of E-mail Lowdependence to nicotine was associated with a midhighuse of E-mail use (OR2 = 203 CI95 122-338) Furtheradjustments did not materially alter these associationsThese results are consistent with crude analysisAll these factors were also associated to SMS and inter-
net frequency of use except that dependence to nicotinedid not remain statistically significant Conversely womenwere more likely to use SMS (OR1 = 215 CI95 163-285 and OR2 = 305 CI95 240-388)When the frequency of E-mail SMS and internet use
was analyzed separately by age social class and educa-tional level the influence of the other factors was similaras among the whole sample studied (results not shown)for instance the direction of the associations of young
age and higher social class remained analogous and sta-tistically significant in both individuals with high andlow educational level
DiscussionPrincipal findingsBy means of a representative sample of the smokingpopulation attended in the public primary care systemwe have studied the differences among smokers in rela-tion to the use of different ICTs (Internet Email andSMS messages) including among the variables demo-graphic characteristics socioeconomic status and smok-ing profile This study shows that the three studied ICTsare widely used especially among the population under45 women more favoured social class of higher educa-tion level and those with lower consumption It alsoshowed that cigarette consumption had started at ayounger age in ICTs usersOur data show that 844 of smokers use some of the
ICTs studied being the use of Internet sms and E-mailand 715 (560 for high use) 740 (508 for highuse) and 653 (498 for high use) respectively Thefrequency of access to web of our study is comparable tothe general population of Spain in 2012 (708) [15] andto some international studies (655) [1429] Amongsmokers Hunt et al showed that 635 were internetusers [30] Some studies have attempted to characterizethe group of internet users (not only smokers) who areinterested in finding information about smoking onhealth-related web pages but not a clear common pro-file has been found [3132] Weaver and colleagues sug-gested that females white respondents people aged55ndash64 and computer owners were positively associated

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

and individuals with a higher educational level Thoseindividuals from lower social classes tended to declareno use or lower use of E-mail text messaging and internetRegarding tobacco consumption variables the number ofcigarettes smoked per day and nicotine dependence washigher among non users of ICTs Conversely users ofboth low and high frequency declared a lower age of startof tobacco consumptionFinally we analyzed factors affecting ICTs use (Tables 3
4 and 5) by comparing no use vs low frequency of use(OR1) and no use vs midhigh frequency of use (OR2)Binary logistic adjusted analysis showed that age wasthe strongest predictor of E-mail frequency use (for in-dividuals aged 18ndash35 OR1 = 334 CI951397-8025and OR2 = 600 CI95 301-953) Higher social class(OR1 = 161 CI95108-234 and OR2 = 429 CI95311-593) and educational level (OR1 = 222 CI95 156-315 and OR2 = 408 CI95 303-548) were also posi-tively associated to the frequency of use of E-mail Lowdependence to nicotine was associated with a midhighuse of E-mail use (OR2 = 203 CI95 122-338) Furtheradjustments did not materially alter these associationsThese results are consistent with crude analysisAll these factors were also associated to SMS and inter-
net frequency of use except that dependence to nicotinedid not remain statistically significant Conversely womenwere more likely to use SMS (OR1 = 215 CI95 163-285 and OR2 = 305 CI95 240-388)When the frequency of E-mail SMS and internet use
was analyzed separately by age social class and educa-tional level the influence of the other factors was similaras among the whole sample studied (results not shown)for instance the direction of the associations of young
age and higher social class remained analogous and sta-tistically significant in both individuals with high andlow educational level
DiscussionPrincipal findingsBy means of a representative sample of the smokingpopulation attended in the public primary care systemwe have studied the differences among smokers in rela-tion to the use of different ICTs (Internet Email andSMS messages) including among the variables demo-graphic characteristics socioeconomic status and smok-ing profile This study shows that the three studied ICTsare widely used especially among the population under45 women more favoured social class of higher educa-tion level and those with lower consumption It alsoshowed that cigarette consumption had started at ayounger age in ICTs usersOur data show that 844 of smokers use some of the
ICTs studied being the use of Internet sms and E-mailand 715 (560 for high use) 740 (508 for highuse) and 653 (498 for high use) respectively Thefrequency of access to web of our study is comparable tothe general population of Spain in 2012 (708) [15] andto some international studies (655) [1429] Amongsmokers Hunt et al showed that 635 were internetusers [30] Some studies have attempted to characterizethe group of internet users (not only smokers) who areinterested in finding information about smoking onhealth-related web pages but not a clear common pro-file has been found [3132] Weaver and colleagues sug-gested that females white respondents people aged55ndash64 and computer owners were positively associated

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

and individuals with a higher educational level Thoseindividuals from lower social classes tended to declareno use or lower use of E-mail text messaging and internetRegarding tobacco consumption variables the number ofcigarettes smoked per day and nicotine dependence washigher among non users of ICTs Conversely users ofboth low and high frequency declared a lower age of startof tobacco consumptionFinally we analyzed factors affecting ICTs use (Tables 3
4 and 5) by comparing no use vs low frequency of use(OR1) and no use vs midhigh frequency of use (OR2)Binary logistic adjusted analysis showed that age wasthe strongest predictor of E-mail frequency use (for in-dividuals aged 18ndash35 OR1 = 334 CI951397-8025and OR2 = 600 CI95 301-953) Higher social class(OR1 = 161 CI95108-234 and OR2 = 429 CI95311-593) and educational level (OR1 = 222 CI95 156-315 and OR2 = 408 CI95 303-548) were also posi-tively associated to the frequency of use of E-mail Lowdependence to nicotine was associated with a midhighuse of E-mail use (OR2 = 203 CI95 122-338) Furtheradjustments did not materially alter these associationsThese results are consistent with crude analysisAll these factors were also associated to SMS and inter-
net frequency of use except that dependence to nicotinedid not remain statistically significant Conversely womenwere more likely to use SMS (OR1 = 215 CI95 163-285 and OR2 = 305 CI95 240-388)When the frequency of E-mail SMS and internet use
was analyzed separately by age social class and educa-tional level the influence of the other factors was similaras among the whole sample studied (results not shown)for instance the direction of the associations of young
age and higher social class remained analogous and sta-tistically significant in both individuals with high andlow educational level
DiscussionPrincipal findingsBy means of a representative sample of the smokingpopulation attended in the public primary care systemwe have studied the differences among smokers in rela-tion to the use of different ICTs (Internet Email andSMS messages) including among the variables demo-graphic characteristics socioeconomic status and smok-ing profile This study shows that the three studied ICTsare widely used especially among the population under45 women more favoured social class of higher educa-tion level and those with lower consumption It alsoshowed that cigarette consumption had started at ayounger age in ICTs usersOur data show that 844 of smokers use some of the
ICTs studied being the use of Internet sms and E-mailand 715 (560 for high use) 740 (508 for highuse) and 653 (498 for high use) respectively Thefrequency of access to web of our study is comparable tothe general population of Spain in 2012 (708) [15] andto some international studies (655) [1429] Amongsmokers Hunt et al showed that 635 were internetusers [30] Some studies have attempted to characterizethe group of internet users (not only smokers) who areinterested in finding information about smoking onhealth-related web pages but not a clear common pro-file has been found [3132] Weaver and colleagues sug-gested that females white respondents people aged55ndash64 and computer owners were positively associated

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

with the interest of finding information on the web[32] Our study shows that smokers from higher socialclass and educational level as well as young age are as-sociated to web use which is in accordance with someother studies [303334] Regarding gender our studyshows more women users (522-536) along with otherstudies [3335] but results remain inconclusively [3034]Chander and collaborators found that higher educationwas associated with the use of these ICTs among HIVcarriers [36]There are few studies that report sms use among the
general population According to the Forrester ResearchMobile Media Application Spending Forecast lsquomore than6 billion of SMS are sent each day and text messageusers receive an average of 35 messages per dayrsquo Con-cretely more than 80 of the US population owning amobile phone and with almost 70 of these phoneowners regularly sending or receiving text messages[3738] In Spain there are 334 millions of cell phoneusers (858 of people aged 15 or older) [15] No datahas been found regarding sms use among smokers ex-cept for the study published by Chander et al that re-ported that 39 of HIV positive smokers used sms andits use was mainly associated to higher educational level[36] Data from the control group of a clinical trial thatused text message to help smokers to quit showed thatmostly were unemployed students and manual workers(55) which was similar to our findings (632-498)but were younger and tended to be more males (55 vs439) [39]Regarding the use of email we have not found data to
inform the use of these ICTs by smokers Data concern-ing the populations that have participated in trials usingemail in treating smokers show similarities in somesocio-demographic factors (younger age and predomin-antly female participants) [4041] although Polosa andcollegues reported a higher participation of men [42]Data from our study showed more consumption of to-
bacco among non-users of the three technologies (meancigarettes per day 173 (SD 114)) compared to users(mean cigarettes per day 150 (SD 880)) Stoddard ampAuguston reported similar cigarette consumption butdid not find differences between those who used internetand those who didnrsquot [34] Besides our data showed thatage of onset of smoking we report that our study showsdifferences between among ICTs users was lower (170(SD 40)) than non users (186 (SD 66)) Neither similarfindings nor possible explanations have found in theliteratureThe three technologies used show a very high use
among smokers which suggests that they could be po-tentially very useful in interventions based on exclusiveuse use in combination or supporting face-to-face inter-ventions Each of the three technologies studied have
their own advantages and disadvantages Disadvantagesinclude the development of a private and secure envir-onment to regulate its use refusal to use them and lackof experience and time on its use [21344344] E-mailand SMS would probably be the most feasible to usesince both patient and sanitary professional can check itat their own convenience which allows certain time torespond (preferably in the first 48 hours) can diminishvisits to the primary care center are helpful on sendingreminders improve medication adherence and self-management of some chronic illnesses and can providevisual information [212225] Whilst E-mail is a quitecheap technology in Spain SMS comprise higher costsin Spain since they are not chargeless Although websitesshare some of these advantages can transmit a feeling ofimpersonality to certain users Additionally the use ofthese technologies should be tailored thus the potentialtherapeutic use rises if these technologies are used bythe sanitary professional who knows and treats the pa-tient [18] Moreover the relationship among patientand sanitary professional can be deepened and encour-aging attitudes can be generated if the experience ispositive [43]
Limitation and future directionsOne of the main limitations of the study is its design across-sectional study does not allow causal associationsThis study was conducted in a population of smokersand we were not able to acknowledge the differences be-tween this group and the general population In factparticipation in the study was offered to several refereesof primary care research of all the Spanish territory andonly those form Catalonia Aragoacuten and Salamanca ac-cepted to participate maybe the ICT use in other re-gions of Spain could be different We only studied thosewho came to the primary healthcare centres consideringthat the vast majority of the Spanish population attendthem once a year [84546] and were potential users ofthese technologies Consequently primary care can bean ideal setting to recruit participants from the generalpopulation to whom ICT based interventions can betestedWe did not evaluate barriers to the use of these tech-
nologies and did not consider the costs associated withmobile phone use and texting which may limit its use inbehavioural interventions However it is an ongoingqualitative and quantitative research by our researchgroup that will analyze the barriers and aids to the useof ICTs among smokers and health professionals Thequalitative study will also try to assess if patients wouldengage into a cessation program since we were not ableto gather this information on the present studyRegarding cell phone use we have only asked for the
use of sms in our population but mobile applications

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy

(mobile Apps) are being developed to help smokers toquit and can post a new paradigm on smoking cessation[47] No data was gathered among the use of social net-working sites such as Twitter that can be a potentialtool to support smoking cessation [48]Our results show differences on nicotine dependence
levels among ICT users and not users (p = 0004) howeverthe clinical relevance of this difference remains incon-clusively in using ICTs to help smokers quit Possiblymore intensive ICTs interventions (such as more smsor E-mails) will be needed on those smokers withhigher nicotine dependence (with higher Fagerstroumlmtest levels and higher number of cigarettes smoked)The final model used in the binary logistic analysis in-
cludes social class and educational level that may resultin over adjustment However in the context of a globaleconomic crisis in our country nowadays education can-not be used as an indicator of occupation since manypeople with higher education are currently working injobs that do not match their educational level
ConclusionsIn conclusion the use of ICTs for smoking cessation ispromising since can reach an extensive range of popula-tion with mobile phones being the technology withbroadest potential Considering the high prevalence ofsmoking in the general population and the broad use ofICTs in smokers the health benefits are clear in termsof effectiveness and cost-effectiveness for treating thesepatients By knowing the profile of smokers who useICTs primary care health professional can offer the pos-sibility to use a specific ICT according to the smokerrsquosprofile in order to maximise the probability of success Itis necessary to develop future clinical trials to determinethe feasibility acceptability and effectiveness of thesetechnologies as individual or complementary interven-tions with pharmacotherapy
