ethods

tudy Population and Design

he World Health Survey (WHS), a large cross-sectionaltudy, was administered in 70 countries in 2002–2003 to assessealthcare expenditures, adult mortality, birth history, risk

actors, chronic health conditions, and the coverage ofealth interventions (www.who.int/healthinfo/survey/en/index.tml). Countries included in the survey comprise a largeroportion of the world’s population, geographically repre-ent the six WHO regions, and include high-, middle-, andow-income countries. In addition to the standard questionssked of all participants, each country was able to selecturther questionnaire modules, one of which included ques-ions related to dietary habits and nutrition. Fifty-two mainlyow- and middle-income countries administered the nutrition

odule. These countries represent all regions of the world,ith 14 countries from the European region, 18 from thefrican region, six from the Americas, four from the Easternediterranean region, five from the Southeast Asia region,

nd five from the Western Pacific region.The WHS’s sampling frame covered 100% of a country’s

ligible population, meaning that the entire national territoryas included, and particular ethnic groups or geographicreas were not excluded from the sampling frame. Excep-ional circumstances that may have precluded full nationaloverage, such as accessibility and conflict, were discussedith WHO sampling experts and noted in the data record.he target population included any adult, male or female,ged �18 years living in private households, who were not outf the country during the survey period.Face-to-face interviews were conducted by lay people with at

east a high school education. Interviewers attended a week-ong training course using a standard protocol manual andarticipated in field interviews that were reviewed by supervi-ors prior to actual data collection. Random national samples,sing a multistage cluster design, were obtained in all coun-ries except China, Comoros, the Republic of Congo, Côte’Ivoire, India, and the Russian Federation. A Kish table wassed to select respondents within each household (www.who.

nt/healthinfo/survey/en/index.html).17,18

uestionnaire

uestionnaires were translated using a standard WHO pro-ocol with both translation and back-translation of the instru-

ent. Independent bilingual experts reviewed and verifiedhe quality of the translations prior to field implementa-ion.17,18 The WHS was not a comprehensive nutrition survey

easuring whole diets, but rather sought measurement ofruit and vegetable consumption only. Two questions wereoncerned with intake of fruits and vegetables, using the4-hour dietary recall data as the gold standard.19 The survey

uestions were: How many servings of fruit do you eat on a typical g

ay 2009

ay? and How many servings of vegetables do you eat on a typicalay?Researchers were trained to show all respondents a nutri-

ion risk factor card that indicates both in writing andictorially general categories, amounts, and examples ofruits and vegetables in an attempt to standardize the servingize and number of servings reported. Each nutrition card waseviewed and updated by each survey country to reflect theest examples of fruits and vegetables to be considered theost typical for that country. The nutrition card categorized

ne serving of vegetables into one of three groups: (1) oneup of raw green leafy vegetables such as spinach or salad;2) one-half cup of other vegetables cooked or chopped raw,uch as tomatoes, carrots, pumpkin, corn, Chinese cabbage,eans, or onions; and (3) one-half cup vegetable juice. Theutrition card categorized one serving of fruit into one of

hree groups: (1) one medium size piece of fruit, such as anpple, banana, or orange; (2) one-half cup cooked, chopped,r canned fruit; and (3) one-half cup fruit juice, not artifi-ially flavored. Researchers were also instructed to tell respon-ents to consider a “typical day” to be one when a person isating fruits or vegetables and not the average over the period ofnquiry.19 Informed consent was obtained from all respondents,nd the study received ethics approval at each site.

tudy Sample and Methods

ata analysis was conducted in the summer of 2008. Thereere 229,180 WHS participants within the 52 countries. Of

hese, 199,032 participants provided complete information inhe nutrition module. For these reports, people aged �18ears and those aged �99 years were excluded. Observationshat were missing information on age, gender, urbanicity, orampling weight were also excluded, for a total of 196,373bservations. Observations from Slovenia and Guatemalaere kept, although sampling and urbanicity informationere absent for Slovenia, and sampling information wasbsent for Guatemala. People aged between 70 and 99 yearsere grouped into the “70 plus” age category.Economic status was measured using the asset-based ap-

roach developed by Ferguson and colleagues,20 which haseen used in previous cross-national studies of economictatus and health in developing countries.21,22 Previous re-earch23 has shown that asset-based approaches can providealid and reliable, if imperfect, estimates of household wealthr consumption, and Ferguson and colleagues20 showedoderate-to-high correlations between the asset index andeasured income and consumption data in Greece, Peru,

nd Pakistan. In addition, Wagstaff and Watanabe24 showedo significant difference in estimating inequalities in childalnutrition within 19 low-income countries using an asset-

ased or consumption-based approach for measuring eco-omic status.This approach assumes that economic status is an unob-

erved latent variable and is estimated by a random-effectsrobit model using measures of household ownership ofssets (e.g., a refrigerator, a radio, or a car); access to servicese.g., drinking water); and known predictors of income (e.g.,ge and education). Coefficients on the asset variables fromhe model indicate thresholds on the latent income scalebove which households are more likely to own particularssets (i.e., if a household’s estimated permanent income is

reater than the asset threshold, there is a �0.5 probability

hat they own the item). This asset scale is then applied toach household to estimate permanent income. Estimates ofermanent income were categorized into quintiles withinach country.Prevalence reports according to income groups were lim-

ted to a smaller sample size of 179,066 observations due toissing income information including all observations fromurkey. Country prevalence estimates were age standardized

o the 1999 WHO standard population (www.who.int/infobase)nd weighted according to the sampling design (based onelection probability, nonresponse, and post-stratification)ith the exception of Guatemala and Slovenia. To examine if

here were significant differences according to gender, age,rbanicity, or income in the risk of low fruit and vegetableonsumption, multivariable Poisson regression analyses with aobust error variance were conducted for each country sepa-ately. This modified Poisson regression approach providesore accurate estimates and CIs for binary outcomes than

ogistic regression when the outcome of interest has a highevel of prevalence in the population.25,26 Therefore, thencidence rate ratios (IRRs) and 95% CIs are reported. Forountries with no missing data, IRRs were adjusted forender, age, urbanicity, and income quintile. Surveys fromlovenia were missing data on urbanicity; those from Turkeyere missing data on income.Countries are reported as indicating significant gender or

rbanicity differences with p�0.05 using clustered robust SEsith the clusters formed of a country’s primary sampling unitsPSUs) used in the WHS. Information on PSUs was missingor Guatemala, Slovenia, and Zambia. Robust SEs were usedor these three countries. Results of separate country analysesre provided as supplementary files. Data were analyzed usingtata, version 10. Sampling weights were not applied ineporting pooled prevalence for age strata, urbanicity, orncome quintiles.

efinition of Low Fruit and Vegetable Consumption

ow fruit and vegetable consumption was defined by theHO panel on diet, nutrition, and prevention of chronic

iseases as consuming fewer than five servings of fruitsnd/or vegetables daily. The panel recommends an individ-al intake of at least 400g of fruits and vegetables a day, thequivalent of five servings, which was used as the cutoff forow fruit and vegetable consumption.13,14

ervings of fruits and/or vegetables daily (81.1% of mennd 71.1% of women).27 The Health Survey for Englandeported a prevalence of low fruit and vegetable consump-ion of 78% for men and 74% for women.28 Results of the004–2005 National Health Survey in Australia indicatedhat 52% of men and 40% of women reported consumingewer than two servings of fruit daily, and 88% of men and4% of women reported consuming fewer than fourervings of vegetables daily.29

Direct comparisons of current results with those ofther studies should be undertaken with caution. Theirect comparison of results is limited in the current worky the use of different questionnaires; the inclusion ofifferent age groups (people aged �16 years in theealth Survey of England and people aged �18 years in

he current work and the BRFSS); different definitions ofow fruit and vegetable consumption; and the comparisonf high-income countries to primarily low- and middle-

ncome countries. It is also well known that fruit andegetable consumption patterns display seasonal variabil-ty, which further complicates the comparison of resultsithin and across countries.15 The time period for dataollection in each country in the WHS is available at thenfoBase Home Page (www.who.int/infobase).

Many developing nations lack data on fruit and vegeta-le consumption in their populations (www.who.int/

nfobase).12 Baseline data are available, however, forouth Africa. Schneider and colleagues30 calculated theverage daily intake of fruits and vegetables in 2000sing prevalence data from dietary surveys. Based onhese calculations, approximately 80% of adults aged15 years in South Africa, or 11.1 million men and 12.5illion women, eat fewer than the recommended five

ervings of fruits and vegetables each day.30 Prevalencealues are higher from this study than those obtainedsing the WHS data and may be attributed to differ-nces in study design, including its smaller sample size,roader age range (�15 years compared to �18 years

n the WHS), number of urban residents, and an earlierime period for the dietary surveys (2000 compared to003).The ranking of country prevalence values withinHO regions was relatively consistent for men andomen. Low fruit and vegetable consumption preva-

ence was particularly high for both men and women inhina, Nepal, Ecuador, and Mauritania within their

espective regions. Conversely, the proportion of mennd women consuming an inadequate amount of fruitsnd vegetables daily was outstandingly low in Bang-adesh, Ukraine, Malawi, and Ghana in comparison tohe other countries within their respective regions. Thefrican region displayed the greatest heterogeneity in

ow fruit and vegetable consumption; Africa has alsohown greater heterogeneity in other chronic diseaseisk factors including physical inactivity, tobacco use,nd alcohol consumption (www.who.int/infobase).18

ne potential explanation for the observed variability t

ay 2009

ay be the between-country diversity in this region andhe differing stages of economic, political, and techno-ogic development they are experiencing. Interpreta-ion of the rankings of country prevalence of low fruitnd vegetable consumption should be undertaken withaution because of differences in seasonal variability.urther analyses should consider seasonal patterns inruit and vegetable consumption as they relate to theime period of data collection for each country.

With the exception of the slight decrease in preva-ence of low fruit and vegetable consumption from the0–49 year age stratum to the 50–59 year age stratum,here is an increasing prevalence with age. Previousndings27,31–33 from high-income countries, such as the.S. and France, showed that prevalence of low fruit

nd vegetable consumption decreased with age. Resultsf the BRFSS indicated that prevalence of low fruit andegetable consumption decreased with age for whitesnd Hispanics but increased for African Americans.nconsistencies between the current study and previousndings, which come mainly from high-income coun-

ries, may be a result of differences in age-relatedynamics in low- and middle-income countries.Results of the WHS indicate that urbanicity is not

ssociated with low fruit and vegetable consumption inhe overall sample; however, significant differencesere found between urban and rural/peri-urban resi-ents for 11 countries. A paucity of research exists withespect to urbanicity trends in fruit and vegetablentake for adults. Studies conducted in Norway, Esto-ia, Latvia, and Lithuania have shown that adults living

n rural areas consumed fewer fruits and vegetableshan their counterparts living in urban areas, whereasesearch in Finland showed no difference in intakeetween rural and urban areas.34,35

The observed income gradient for the pooled samplen the current work is consistent with results from othertudies. The poorest quintile had the highest preva-ence of low fruit and vegetable consumption (81.6%),hereas the richest quintile had the lowest prevalence73.4%). Research from the U.S. indicates that those inow-income households are less likely to meet the U.S.epartment of Agriculture guidelines for fruit and

egetable consumption.36 The current results provideurther support for studies that indicate that fruit andegetable prices are a barrier to consumption forow-income consumers, and thus developing publicolicies to make fruits and vegetables more affordableor low-income families should be examined.37–39 Al-hough an income gradient is observed for the pooledample, there is some heterogeneity in these results, asot all countries have income gradients in low fruit andegetable consumption.

The reliability and validity of the fruit and vegetableonsumption module within the WHS are quite high.he two questions regarding intake of fruit and vege-

ables, using the 24-hour dietary recall data, are consid-

red the gold standard by the WHO.19 Other strengthsf this questionnaire are that portion sizes and visualues (specific to the country) were offered to respon-ents as a means of better quantifying food intake.40

ecause this method depends on self-reported dataased on memory, there is potential for recall bias;owever, this bias is minimized because the questionsefer to a short period very close to the time of thenterview.40 One main limitation is that this method

ay not provide reliable estimates of the usual intake ofrespondent as a result of day-to-day variations and ofot completing repeated surveys with the same respon-ent. Because the WHS was administered on all days ofhe week and during multiple seasons (depending onhe specific country), there is a reduced likelihood ofbtaining skewed prevalence data resulting from day-o-day variability.

his paper reports the largest population-based world-ide study to examine the prevalence of low fruit andegetable consumption. For many of the countries, datan fruit and vegetable intake have never been previ-usly reported. With the exception of six countries, theesults of this work are based on nationally representa-ive samples from 52 countries, including 196,373 indi-iduals. Results of the current work provide baselinerevalence measures of one important risk factor foreveral chronic diseases around the world. Fruit andegetable consumption varies greatly across countries,ettings, genders, ages, and income levels. This varia-ion is notable because disability, disease, and illnessarallel fruit and vegetable consumption levels.41 Notudies have demonstrated harmful effects of fruit andegetable consumption at recommended levels, andhe one consistent finding is the protective effect ofating whole fruits and vegetables.42

Public health actions at national and internationalevels are necessary. This includes targeting publicealth education and health promotion programs to

he specific context and priority groups within eachountry. As the current work illustrates, there is consid-rable diversity in the specific subpopulations withinach country that show low prevalence of fruit andegetable consumption, based on gender, age, urbanic-ty, and income. Recommendations to increase fruitnd vegetable consumption include, but are not limitedo, increased education on diet and physical activityith a particular emphasis on the importance of con-

uming at least five servings of fruits and vegetablesach day, levying a tax on foods of low nutritional value,mproved food labeling, and stricter controls on the
