This article analyses the relationship between socio-economic status and the prevalence of overweight and obesity in the primary school population in Costa Rica.

A National School Weight/Height Census was disseminated across Costa Rica in 2016. The percentage of children who were overweight or obese was calculated by sex, age and socio-economic indicators (type of institution: private, public, mix; type of geographic location: rural, urban and the level of development of the district of residence: quartiles). A mixed-effects multinomial logistic regression model and mixed-effects logistic regression model were used to analyse the association between the prevalence of being overweight or obese and district socio-economic status.

The survey was carried out in public and private primary schools across Costa Rica in 2016.

In total, 347 366 students from 6 to 12 years were enrolled in public and private primary schools.

The prevalence of overweight and obesity among children was 34·0 %. Children in private schools were more likely to be overweight or obese than students in public schools (OR = 1·10 [1·07, 1·13]). Additionally, children were less likely to be overweight or obese if attending a school in a district of the lowest socio-economic quartile compared with the highest socio-economic quartile (OR = 0·79 [0·75, 0·83]) and in a rural area compared with the urban area (OR = 0·92 [0·87, 0·97]).

Childhood obesity in Costa Rica continues to be a public health problem. Prevalence of overweight and obesity in children was associated with indicators of higher socio-economic status.

To explain patterns of fruit and vegetable consumption in nine former Soviet Union countries by exploring the influence of a range of individual- and community-level determinants.

Cross-sectional nationally representative surveys and area profiles were undertaken in 2010 in nine countries of the former Soviet Union as part of the Health in Times of Transition (HITT) study. Individual- and area-level determinants were analysed, taking into account potential confounding at the individual and area level.

Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia and Ukraine.

Adult survey respondents (n 17 998) aged 18–95 years.

Being male, increasing age, lack of education and lack of financial resources were associated with lower probability of consuming adequate amounts of fruit or vegetables. Daily fruit or vegetable consumption was positively correlated with the number of shops selling fruit and vegetables (for women) and with the number of convenience stores (for men). Billboard advertising of snacks and sweet drinks was negatively related to daily fruit or vegetable consumption, although the reverse was true for billboards advertising soft drinks. Men living near a fast-food outlet had a lower probability of fruit or vegetable consumption, while the opposite was true for the number of local food restaurants.

Overall fruit and vegetable consumption in the former Soviet Union is inadequate, particularly among lower socio-economic groups. Both individual- and community-level factors play a role in explaining inadequate nutrition and thus provide potential entry points for policy interventions, while the nuanced influence of community factors informs the agenda for future research.

The purpose of the present research was to investigate the epidemiological profile of the metabolic syndrome (MetS) and to explore its potential dietary, behavioural and socio-economic determinants among European adults residing in Luxembourg.

Cross-sectional, population-based ORISCAV-LUX survey.

European adults aged 18–69 years residing in Luxembourg.

A total of 1349 Europid adults, who participated in the ORISCAV-LUX survey, were included in the study. The prevalence of MetS was estimated according to the Revised-Adult Treatment Panel (R-ATPIII) criteria. Multivariate logistic regression was used to identify the dietary, behavioural and socio-economic factors independently associated with MetS.

The overall prevalence of MetS was 24·7 % with significant gender difference (18·5 % for women v. 30·8 % for men, P < 0·0001). Age, male gender, primary level of education, physical inactivity, family history of diabetes and hypertension and inadequate protein intake were identified as significant determinants of MetS, after adjusting for other socio-economic, family medical history and lifestyle factors.

MetS is a common condition among Europid adults in Luxembourg and increases dramatically with age, in both genders. Several dietary, socio-economic and behavioural factors explain the disparity observed. These findings highlight the importance of a comprehensive approach to MetS encompassing dietary, lifestyle and socio-economic aspects, both in clinical and community settings.

To describe regional differences between eastern and western Germany with regard to food, nutrient and supplement intake in 9–12-year-old children, and analyse its association with parental education and equivalent income.

Data were obtained from the 10-year follow-up of the two prospective birth cohort studies – GINIplus and LISAplus. Data on food consumption and supplement intake were collected using an FFQ, which had been designed for the specific study population. Information on parental educational level and equivalent income was derived from questionnaires. Logistic regression modelling was used to analyse the effect of parental education, equivalent income and region on food intake, after adjusting for potential confounders.

Germany.

A total of 3435 children aged 9–12 years.

Substantial regional differences in food intake were observed between eastern and western Germany. Intakes of bread, butter, eggs, pasta, vegetables/salad and fruit showed a significant direct relationship with the level of parental education after adjusting for potential confounders, whereas intakes of margarine, meat products, pizza, desserts and soft drinks were inversely associated with parental education. Equivalent income had a weaker influence on the child's food intake.

Nutritional education programmes for school-age children should therefore account for regional differences and parental education.

To examine the sociodemographic determinants of fruit and vegetable (F&V) consumption in England and determine the differential effects of socio-economic variables at various parts of the intake distribution, with a special focus on severely inadequate intakes.

Quantile regression, expressing F&V intake as a function of sociodemographic variables, is employed. Here, quantile regression flexibly allows variables such as ethnicity to exert effects on F&V intake that vary depending on existing levels of intake.

The 2003 Health Survey of England.

Data were from 11 044 adult individuals.

The influence of particular sociodemographic variables is found to vary significantly across the intake distribution. We conclude that women consume more F&V than men; Asians and blacks more than whites; co-habiting individuals more than single-living ones. Increased incomes and education also boost intake. However, the key general finding of the present study is that the influence of most variables is relatively weak in the area of greatest concern, i.e. among those with the most inadequate intakes in any reference group.

Our findings emphasise the importance of allowing the effects of socio-economic drivers to vary across the intake distribution. The main finding, that variables which exert significant influence on F&V intake at other parts of the conditional distribution have a relatively weak influence at the lower tail, is cause for concern. It implies that in any defined group, those consuming the least F&V are hard to influence using campaigns or policy levers.

To evaluate the trends of overweight and obesity prevalences in the population of Catalonia, Spain, aged 18–75 years, and the influence of socio-economic determinants on these prevalence trends.

Analysis based on data from two representative population-based cross-sectional surveys.

Data from the two Evaluations of Nutritional Status in Catalonia (ENCAT 1992–93 and ENCAT 2002–03), Spain. Weights and heights were obtained by direct measurement in standardised conditions by trained interviewers. Overweight and obesity were defined using body mass index (BMI) and waist circumference (WC), categorised according to WHO criteria.

In total, 1015 men and 1233 women from ENCAT 1992–93, and 791 men and 924 women from ENCAT 2002–03.

Mean BMI and mean WC were higher in males in 2002–03 as compared to 1992–93, while for females mean BMI was lower except for the youngest group, and mean WC was higher. In men, overall BMI overweight prevalence remained stable (from 44.1% to 43.7%), while obesity increased (from 9.9% to 16.6%); total WC overweight remained stable (from 21.7 to 23.8%), while WC obesity increased (from 13.1% to 24.4%). In women, overall BMI overweight increased (from 29.1% to 30.1%), whereas BMI obesity remained stable (from 15.0% to 15.2%); total WC overweight decreased (from 21.8% to 17.7%), while WC obesity increased (from 24.5% to 31.1%). The socio-economic and education variables had an influence on BMI and WC overweight and obesity rates mainly on females in both surveys and on the youngest men only in the 1992–93 survey.

Ten-year trends indicate that Catalan males are getting bigger overall (BMI) and around the waistline (WC), while Catalan females only have bigger waistlines (WC). BMI male obesity prevalence has overtaken that of females. WC obesity continues to be more prevalent among females than males.
