To explore complementary feeding practices and identify potential risk factors associated with inadequate complementary feeding practices in Ghana by using the newly developed WHO infant feeding indicators and data from the nationally representative 2008 Ghana Demographic and Health Survey.

The source of data for the analysis was the 2008 Ghana Demographic and Health Survey. Analysis of the factors associated with inadequate complementary feeding, using individual-, household- and community-level determinants, was done by performing multiple logistic regression modelling.

Ghana.

Children (n 822) aged 6–23 months.

The prevalence of the introduction of solid, semi-solid or soft foods among infants aged 6–8 months was 72·6 % (95 % CI 64·6 %, 79·3 %). The proportion of children aged 6–23 months who met the minimum meal frequency and dietary diversity for breast-fed and non-breast-fed children was 46·0 % (95 % CI 42·3 %, 49·9 %) and 51·4 % (95 % CI 47·4 %, 55·3 %) respectively and the prevalence of minimum acceptable diet for breast-fed children was 29·9 % (95 % CI 26·1 %, 34·1 %). Multivariate analysis revealed that children from the other administrative regions were less likely to meet minimum dietary diversity, meal frequency and acceptable diet than those from the Volta region. Household poverty, children whose mothers perceived their size to be smaller than average and children who were delivered at home were significantly less likely to meet the minimum dietary diversity requirement; and children whose mothers did not have any postnatal check-ups were significantly less likely to meet the requirement for minimum acceptable diet. Complementary feeding was significantly lower in infants from illiterate mothers (adjusted OR=3·55; 95 % CI 1·05, 12·02).

The prevalence of complementary feeding among children in Ghana is still below the WHO-recommended standard of 90 % coverage. Non-attendance of postnatal check-up by mothers, cultural beliefs and habits, household poverty, home delivery of babies and non-Christian mothers were the most important risk factors for inadequate complementary feeding practices. Therefore, nutrition educational interventions to improve complementary feeding practices should target these factors in order to achieve the fourth Millennium Development Goal.

Despite differences in obesity and ill health between urban and rural areas in the UK being well documented, very little is known about differences in dietary patterns across these areas. The present study aimed to examine whether urban/rural status is associated with dietary patterns in a population-based UK cohort study of children.

Dietary patterns were obtained using principal components analysis and cluster analysis of 3 d diet records collected from children at 10 years of age. Rurality was obtained from the 2001 UK Census urban/rural indicator at the time of dietary assessment. General linear models were used to examine the relationship between rurality and dietary pattern scores from principal components analysis; multinomial logistic regression was used to assess the association between rurality and dietary clusters.

The Avon Longitudinal Study of Parents and Children (ALSPAC), South West England.

Children (n 5677) aged 10 years (2817 boys and 2860 girls).

After adjustment, increases in rurality were associated with increased scores on the ‘health awareness’ dietary pattern (β=0·35; 95 % CI 0·14, 0·56; P<0·001 for the most rural compared with the most urban group) and lower scores on the ‘packed lunch/snack’ dietary pattern (β=−0·39; 95 % CI −0·59, −0·19; P<0·001 for the most rural compared with the most urban group). The odds ratio for participants being in the ‘healthy’ compared with the ‘processed’ dietary cluster for the most rural areas was 1·61 (95 % CI 1·05, 2·49; P=0·02) compared with those in the most urban areas.

There is evidence to suggest that differences exist in dietary patterns between rural and urban areas. Similar results were found using two different methods of dietary pattern analysis, showing that children residing in rural households were more likely to consume healthier diets than those in urban households.

To investigate the associations of household and neighbourhood socio-economic position (SEP) with indicators of both under- and overnutrition in adolescents and to explore sex differences.

Analysis of anthropometric, household and neighbourhood SEP data from the Birth to Twenty Plus cohort born in 1990. Anthropometric outcomes were BMI (thinness, overweight and obesity) and percentage body fat (%BF; low, high). Associations between these and the household wealth index, caregiver education and neighbourhood SEP tertile measures were examined using binary logistic regression.

Johannesburg–Soweto, South Africa.

Adolescents aged 17–19 years (n 2019; 48·2 % men).

Women had a significantly higher combined prevalence of overweight/obesity (26·2 %) than men (8·2 %) whereas men had a significantly higher prevalence of thinness than women (22·2 % v. 10·6 %, respectively). Having a low neighbourhood social support index was associated with higher odds of high %BF in women (OR=1·59; 95 % CI 1·03, 2·44). A low household wealth index was associated with lower odds of both overweight (OR=0·31; 95 % CI 0·12, 0·76) and high %BF in men (OR=0·28; 95 % CI 0·10, 0·78). A low or middle household wealth index was associated with higher odds of being thin in men (OR=1·90; 95 % CI 1·09, 3·31 and OR=1·80; 95 % CI 1·03, 3·15, respectively). For women, a low household wealth index was associated with lower odds of being thin (OR=0·49; 95 % CI 0·25, 0·96).

The study highlights that even within a relatively small urban area the nutrition transition manifests itself differently in men and women and across SEP indicators. Understanding the challenges for different sexes at different ages is vital in helping to plan public health services.

We examined the association between unhealthy snacking at school and academic outcomes in students from the Santiago Metropolitan Region (Chile).

Cross-sectional population-based study.

We measured the nutritional quality of snacks at school using an FFQ, and accounting for the amounts of saturated fat, fibre, sugar and salt in the foods, and academic outcomes using national standardized test scores in Language and Mathematics. Multivariate regression analyses modelled the relationship between unhealthy snacking at school (exposure), potential confounders and performance in Mathematics and Language (outcomes).

Random sample of 1073 students (13·1 (sd 2·3) years old) attending public, partially subsidized and private schools.

Fifty-six per cent of students ate items at snack time that were high in fat, sugar, salt and energy, and thus were considered to have unhealthy snaking. Thirty-six per cent and 8 % were considered to have poor-to-fair and healthy snacking, respectively. Unhealthy snacking significantly lowered the odds of good academic performance in both domains. Students having unhealthy snacks were 56 % less likely to pass in Language (fully adjusted OR=0·44; 95 % CI 0·23, 0·85) and 66 % less likely to pass in Mathematics (fully adjusted OR=0·34; 95 % CI 0·19, 0·64) compared with students having healthy snack items.

Schoolchildren eating unhealthy foods at snack time had worse academic performance in Language and Mathematics, as measured by a standardized test. Although association does not imply causation, these findings support the notion that academic and health-related behaviours are linked. More research is needed on the effect of school health programmes on educational outcomes.

Malnutrition is common in patients admitted to hospital due to acute illness and contributes to negative patient outcomes. In Slovakia there is a lack of relevant data on malnutrition in hospitalized patients, particularly based on chronic co-morbidity and survival. The aim of the present study was to explore the prevalence of malnutrition in hospitalized chronic patients, its relationship to co-morbidity and its impact on 10-year survival.

Retrospective cohort study.

Nutritional status was estimated by Subjective Global Assessment (SGA), BMI and serum albumin level. Survival was assessed from the National Insurance Registry over a 10-year period. The association between nutritional status measured by SGA and 10-year survival controlling for age, gender, BMI and serum albumin was analysed using Cox regression.

Data were taken from the medical records of 202 consecutively admitted chronic patients.

Median age was 63·5 years; 55·4 % were males; median BMI was 25·9 kg/m2; median serum albumin level was 39·0 g/l. Based on SGA evaluation, 38·1 % did not have sufficient nutritional status (SGA classification B and C). Malnutrition was more common in patients who were older (P=0·023), with lower BMI (P<0·001), who had gastrointestinal (P=0·049) and oncologic co-morbidity (P=0·021) and lower albumin level (P=0·049). In-hospital mortality was 3 %, but during the following 10 years 52 % died. Cox regression analysis controlling for age, gender, BMI and serum albumin showed that SGA was an independent predictor of death (hazard ratio=1·55; 95 % CI 1·04, 2·32; P=0·031).

SGA is a simple screening tool that can be routinely used in hospitalized Slovak medical patients to predict the risk of death. Improving patient nutrition could thus reduce mortality.

To examine which factors act as mediators between parental educational level and children's fruit and vegetable (F&V) intake in ten European countries.

Cross-sectional data were collected in ten European countries participating in the PRO GREENS project (2009). Schoolchildren completed a validated FFQ about their daily F&V intake and filled in a questionnaire about availability of F&V at home, parental facilitation of F&V intake, knowledge of recommendations about F&V intake, self-efficacy to eat F&V and liking for F&V. Parental educational level was determined from a questionnaire given to parents. The associations were examined with multilevel mediation analyses.

Schools in Bulgaria, Finland, Germany, Greece, Iceland, the Netherlands, Norway, Portugal, Slovenia and Sweden.

Eleven-year-old children (n 8159, response rate 72%) and their parents.

In five of the ten countries, children with higher educated parents were more likely to report eating fruits daily. This association was mainly mediated by knowledge but self-efficacy, liking, availability and facilitation also acted as mediators in some countries. Parents’ education was positively associated with their children's daily vegetable intake in seven countries, with knowledge and availability being the strongest mediators and self-efficacy and liking acting as mediators to some degree.

Parental educational level correlated positively with children's daily F&V intake in most countries and the pattern of mediation varied among the participating countries. Future intervention studies that endeavour to decrease the educational-level differences in F&V intake should take into account country-specific features in the relevant determinants of F&V intake.

To examine the vitamin D status, SNP of the vitamin D receptor gene (VDR) and the effects of vitamin D supplementation on parathyroid hormone and insulin secretion in adult males with obesity or normal weight in a subtropical Chinese city.

An intervention trial.

Shenzhen City, Guangdong Province, China.

From a cross-sectional survey conducted from June to July, eighty-two normal-weight and ninety-nine obese males (18–69 years) were screened to analyse their vitamin D status and for five SNP of VDR. From these individuals, in the same season of a different year, obese and normal-weight male volunteers (twenty-one per group) were included for an intervention trial with oral vitamin D supplementation at 1250 µg/week for 8 weeks.

For the survey, there was no significant difference (P>0·05) in baseline circulating 25-hydroxyvitamin D concentrations or in the percentages of participants in different categories of vitamin D status between the two groups. The VDR SNP, rs3782905, was significantly associated with obesity (P=0·043), but none of the examined SNP were correlated with serum 25-hydroxyvitamin D when adjusted for age, BMI and study group. After vitamin D supplementation, serum 25-hydroxyvitamin D concentration, hypersecretions of parathyroid hormone and insulin, and insulin resistance in the obese were changed beneficially (P<0·05); however, the increase in serum 25-hydroxyvitamin D was less than that of the normal-weight men.

For obese and normal-weight men of subtropical China, the summer baseline vitamin D status was similar. However, oral vitamin D supplementation revealed a decreased bioavailability of vitamin D in obese men and ameliorated their hypersecretion of parathyroid hormone and insulin resistance.

To assess the prevalence of and explanations for wheat avoidance, including reported symptoms, diagnoses and information sources influencing the decision to avoid wheat, and to investigate potential psychological predictors of this behaviour.

Cross-sectional population survey.

The study was conducted in Australia, using a nationwide postal omnibus survey.

Adults aged 18 years and over (n 1184; 52·9 % female) selected at random from the Australian Electoral Roll.

With cases of stated and suspected coeliac disease (1·2 %) excluded, 7·3 % of the sample reported adverse physiological effects, predominantly gastrointestinal, that they associated with wheat consumption. Few among this group (5·7 %) claimed a formally diagnosed intolerance or allergy requiring avoidance of wheat-based foods. Symptomatic wheat avoidance was highly correlated with dairy avoidance and predicted by gender (female), lesser receptiveness to conventional medicine and greater receptiveness to complementary medicine, but not by neuroticism, reasoning style or tendency to worry about illness.

The data indicate that many adult Australians are consciously avoiding consumption of wheat foods, predominantly without any formal diagnosis. Reported symptoms suggest a physiological but not allergenic basis to this behaviour. Questions to be answered concern whether symptoms are attributed correctly to wheat, the agents (wheat components, dietary factors or additives) and physiological mechanism(s) involved, the nutritional adequacy of avoiders’ diets, and the clinical and psychosocial processes that lead a substantial number of adults to avoid consuming wheat (or any other dietary factor) apparently independently of a medical diagnosis.

The present study investigated the current status of fruit and vegetable intake among seniors and assessed the relationship between personal background factors, social psychological factors and environmental factors of the study participants and their fruit and vegetable consumption behaviour.

Research data were collected through individual interviews using a questionnaire developed by the authors. SPSS for Windows 15·0 statistical software was used to process and analyse the data.

Elderly individuals sampled from all twenty-nine administration units of Keelung City’s Renai District were interviewed.

Study participants included 398 residents aged 65 years or older.

On average, study participants ate five daily servings of fruits and vegetables on 2·86 d/week. The important variables influencing fruit and vegetable consumption were education level, outcome expectancy, social support, self-efficacy, frequency of dining out and role modelling. Educated participants consumed more fruits and vegetables than those without education. Outcome expectancy, social support, self-efficacy and role modelling had positive impacts on fruit and vegetable intake, but frequency of dining out had a negative impact on fruit and vegetable intake. The significant predictors of fruit and vegetable intake behaviour were education level, outcome expectancy, social support and frequency of dining out. Among those variables, social support was the most influential factor.

Our findings supported the conclusion that health education strategies to increase fruit and vegetable intake among seniors should include the variables of social support and outcome expectancy.

The present paper reports on a quality improvement activity examining implementation of A Better Choice Healthy Food and Drink Supply Strategy for Queensland Health Facilities (A Better Choice). A Better Choice is a policy to increase supply and promotion of healthy foods and drinks and decrease supply and promotion of energy-dense, nutrient-poor choices in all food supply areas including food outlets, staff dining rooms, vending machines, tea trolleys, coffee carts, leased premises, catering, fundraising, promotion and advertising.

An online survey targeted 278 facility managers to collect self-reported quantitative and qualitative data. Telephone interviews were sought concurrently with the twenty-five A Better Choice district contact officers to gather qualitative information.

Public sector-owned and -operated health facilities in Queensland, Australia.

One hundred and thirty-four facility managers and twenty-four district contact officers participated with response rates of 48·2 % and 96·0 %, respectively.

Of facility managers, 78·4 % reported implementation of more than half of the A Better Choice requirements including 24·6 % who reported full strategy implementation. Reported implementation was highest in food outlets, staff dining rooms, tea trolleys, coffee carts, internal catering and drink vending machines. Reported implementation was more problematic in snack vending machines, external catering, leased premises and fundraising.

Despite methodological challenges, the study suggests that policy approaches to improve the food and drink supply can be implemented successfully in public-sector health facilities, although results can be limited in some areas. A Better Choice may provide a model for improving food supply in other health and workplace settings.

Early complementary feeding has been shown to increase the risk of overweight, obesity and chronic diseases later in life. Poor compliance with current guidelines on complementary feeding has been reported by Irish studies. The aim of the present paper is to identify predictors of early complementary feeding in order to help health professionals target population groups in greater need of dietary intervention as well as to provide effective advice.

Cross-sectional analysis of the national, longitudinal Growing Up in Ireland study.

Data were derived from the first wave (2007–2008) of the Growing Up in Ireland infant cohort.

A cohort of mothers (n 11 134) from the Republic of Ireland, interviewed when their infants were 9 months of age.

Of the infants, 1469 (13·5 %) had been regularly taking solids in the period between 12 and 16 weeks; this percentage increased to 47·0 % of the sample in the period between 16 and 20 weeks. Timing of formula feeding commencement, high maternal BMI and choosing a relative as the infant's minder were strongly associated with early introduction of solids both in bivariate and multivariate analysis. Those infants who started formula feeding at >4 months were 88·4% less likely to be introduced to solids early compared with those who started at <2 months (OR = 0·116; 95% CI 0·072, 0·186; P < 0·001).

The results demonstrate that biological, social and behavioural aspects exert an important role in infant feeding practices. These findings are relevant to the design of policies and intervention programmes aimed at educating parents.

There have been inconsistent results published regarding the relationship between dyslipidaemia and an increased risk of colorectal neoplasia (CRN), including colorectal adenoma (CRA) and colorectal cancer (CRC). We conducted a meta-analysis to explore the relationship between dyslipidaemia and CRN.

We identified studies by performing a literature search using PubMed, EMBASE and the Science Citation Index through October 2013.

We analysed thirty-three independent studies reporting the association between CRN and at least one of the selected lipid components, including total cholesterol (TC), TAG, HDL-cholesterol (HDL-C) and LDL-cholesterol (LDL-C).

CRN cases (n 21 809) were identified.

Overall, people with high levels of serum TAG (risk ratio (RR)=1·08; 95 % CI 1·05, 1·12, P<0·00001) and LDL-C (RR=1·07; 95 % CI 1·00, 1·14, P=0·04) presented an increased prevalence of CRN. Subgroup analyses revealed that high levels of serum TC (RR=1·04; 95 % CI 1·01, 1·09, P=0·02), TAG (RR=1·06; 95 % CI 1·03, 1·10, P=0·0009) and LDL-C (RR=1·11; 95 % CI 1·04, 1·19, P=0·003) increased the risk of CRA but not of CRC. No association between serum HDL-C and risk for CRN (including CRA and CRC) was observed.

Both TAG and LDL-C were significantly associated with an increasing prevalence of CRN. High levels of serum TC, TAG and LDL-C were positively associated with CRA but not with CRC. No significant association was observed between levels of serum HDL-C and CRN.

In a cohort of government employees in Rio de Janeiro, Brazil, we investigated prospectively, sex-specific associations between education and BMI trajectories and their potential effect modification by race.

Of the 4030 participants in Phase 1 (1999), 3253 (81 %) participated in Phase 2 (2003) and 3058 (76 %) participated in Phase 3 (2006). Education was categorized as elementary, high school or college graduate. Study participants self-identified as White, Black or Pardo. BMI was calculated from measured weight and height. BMI trajectories were modelled using a generalized additive regression model with mixed effects (GAMM).

The Pro-Saúde Study, a longitudinal investigation of social determinants of health.

Women (n 1441) and men (n 1127) who participated in the three phases of data collection and had complete information for all study variables.

Women and men with less than high school, or only a high school education, gained approximately 1 kg/m2 more than college graduates (women: 1·06 kg/m2 (P<0·001) and 1·06 kg/m2 (P<0·001), respectively; men: 1·04 kg/m2 (P=0·013) and 1·01 kg/m2 (P=0·277), respectively). For women only, race was independently associated with weight gain. Women identifying as Pardo or Black gained 1·03 kg/m2 (P=0·01) and 1·02 kg/m2 (P=0·10), respectively, more than Whites. No effect modification by race was observed for either men or women.

While both lower education and darker race were associated with greater weight gain, gender similarities and differences were observed in these associations. The relationship between weight gain and different indicators of social status are therefore complex and require careful consideration when addressing the obesity epidemic.

The aim of the present study was to gain insight into (i) processed snack-food availability, (ii) processed snack-food salience and (iii) the size of dinnerware among households with overweight gatekeepers. Moreover, associations between gatekeepers’ characteristics and in-home observations were determined.

A cross-sectional observation of home food environments was conducted as part of a baseline measurement of a larger study.

Home food environments of overweight and obese gatekeepers in the Netherlands.

Household gatekeepers (n 278). Mean household size of the gatekeepers was 3·0 (sd 1·3) persons. Mean age of the gatekeepers was 45·7 (sd 9·2) years, 34·9 % were overweight and 65·1 % were obese. Of the gatekeepers, 20·9 % had a low level of education and 42·7 % had a high level of education.

In 70 % of the households, eight or more packages of processed snack foods were present. In 54 % of the households, processed snack foods were stored close to non-processed food items and in 78 % of households close to non-food items. In 33 % of the households, processed snack foods were visible in the kitchen and in 15 % of the households processed snack foods were visible in the living room. Of the dinnerware items, 14 % (plates), 57 % (glasses), 78 % (dessert bowls), 67 % (soup bowls) and 58 % (mugs) were larger than the reference norms of the Netherlands Nutrition Centre Foundation. Older gatekeepers used significantly smaller dinnerware than younger gatekeepers.

Environmental factors endorsing overconsumption are commonly present in the home environments of overweight people and could lead to unplanned eating or passive overconsumption.

Although the benefits of highly active antiretroviral therapy (HAART) have been documented, it is thought to be associated to disturbances in nutritional status. These disturbances may occur early in life and are poorly understood. The present study aimed to investigate the relationship between anthropometric parameters and body composition of perinatally HIV-infected children and adolescents under HAART, according to use and non-use of protease inhibitors.

Cross-sectional study undertaken between August and December 2007. Demographic, socio-economic, clinical and anthropometric data were collected from the patients. The χ2 test, Wilcoxon rank sum test (Mann–Whitney) and t test were used to compare the following variables between users and non-users of protease inhibitors: age, gender, per capita income, HAART exposure, antiretroviral therapy adopted in the last three years, CD4 count, viral load, pubertal stage, nutritional status (BMI-for-age, height-for-age, waist and neck circumferences, triceps skinfold thickness, body fat percentage, upper-arm fat area and upper-arm muscle area).

An HIV/AIDS out-patient clinic, São Paulo, Brazil.

One hundred and fifteen patients (children and adolescents aged 6–19 years).

Protease inhibitors users had a higher prevalence of stunting (P=0·03), lower BMI (P=0·03) and lower percentage of body fat (P=0·05) compared with non-users. There was no statistically significant difference between the HAART regimens and measurements of fat adiposity.

The findings of the study suggest that children and adolescents under protease inhibitors are at higher risk of growth and development deviations, but not at risk of body fat redistribution.

To (i) explore the factors influencing family out-of-home (OH) eating events and (ii) identify possible opportunities for food businesses to support families in making healthier OH choices.

Focus group discussions were conducted with parents (six to eight participants per group) and friendship pair discussions (informal interviews with two children who are friends) were conducted with children (5–12 years) throughout the island of Ireland. Both discussions were audio-recorded and analysed using a thematic content analysis.

Eight focus groups and sixteen friendship pairs were conducted in Northern Ireland and sixteen focus groups and thirty-two friendship pairs were conducted in the Republic of Ireland.

Purposive sampling was used to recruit a sample of non-related parents and children that represented equal numbers of gender, age, socio-economic status and demographic backgrounds.

The main, overarching theme was that families perceived OH eating to be a treat, while health was not currently a key priority for many parents and children. Children were reported to have most responsibility for their own food choice decisions in this environment, with taste and food neophobia having the greatest influences. Parents believed that if food businesses could meet parent and child priorities in addition to health influences, e.g. change cooking methods, and increase flexibility, then families would be more likely to patronise these establishments.

The entire family OH eating experience needs to be considered when developing public health interventions and this research has highlighted key opportunities that caterers could employ to support healthier family OH food choices.

Breast-feeding rates reflect sociodemographic discrepancies. In Mexico, exclusive breast-feeding under 6 months of age has deteriorated among the poor, rural and indigenous populations from 1999 to 2012. Our objective of the present study was to identify the main social obstacles to breast-feeding in a low-income population in Tijuana, Mexico.

Qualitative study using a socio-ecological framework for data collection.

Low-income communities in Tijuana, Mexico.

Mothers (n 66), fathers (n 11), grandparents (n 27) and key informants (n 25).

One hundred and twenty-nine individuals participated in the study: six focus groups (n 53) and fifty-one interviews among mothers, fathers and grandparents; and twenty-five interviews among key informants. Seven social themes were identified: (i) embarrassment to breast-feed in public; (ii) migrant experience; (iii) women’s role in society; (iv) association of formula with higher social status; (v) marketing by the infant food industry; (vi) perception of a non-breast-feeding culture; and (vii) lack of breast-feeding social programmes.

Socio-structural factors influence infant feeding practices in low-income communities in Tijuana. We hypothesize that messages emphasizing Mexican traditions along with modern healthy practices could help to re-establish and normalize a breast-feeding culture in this population. The target audience for these messages should not be limited to mothers but also include family, health-care providers, the work environment and society as a whole.

To describe relationships between the portion sizes of a range of foods commonly consumed by Irish children and adolescents and key indicators of dietary quality on the days they were consumed.

Cross-sectional data from the Irish National Children’s Food Survey (2003–2004; 7 d weighed record) and National Teens’ Food Survey (2005–2006; 7 d semi-weighed record) were used to compare mean values for a number of dietary quality indicators (e.g. energy-adjusted intakes of saturated fat, dietary fibre and Na) across portion size tertiles for a range of foods, on the days the foods were consumed.

The Republic of Ireland.

Nationally representative samples of children aged 5–12 years (n 594) and adolescents aged 13–17 years (n 441).

Relationships between food portion sizes and indicators of dietary quality on the days the foods were consumed were similar in both children and adolescents. Lower dietary energy density and saturated fat intakes, and higher dietary fibre intakes, were observed on the days larger portions of fruit and boiled potatoes were consumed. Higher dietary energy density and lower micronutrient intakes were observed on the days larger portions of sugar-sweetened beverages were consumed. Higher Na intakes were observed on the days larger portions of frying meats were consumed.

The current work identifies foods for which larger portion sizes may be associated with positive dietary attributes, as well as the opposite. Findings will form an evidence base from which more specific dietary guidance relating to portion size may be developed for Irish children and adolescents.

The present study aimed to identify dietary patterns and determine the relationship between dietary patterns and cognitive ability among 12- to 13 year-old Malay adolescents in the urban areas of Gombak district in Selangor, Malaysia.

Data on sociodemographic background were obtained from parents. Height and weight were measured and BMI-for-age was determined. Adolescents were interviewed on their habitual dietary intakes using a semi-quantitative FFQ. Cognitive ability was assessed using the Wechsler Nonverbal Scale of Ability in a one-to-one manner. Dietary patterns were constructed using principal component analysis based on thirty-eight food groups of the semi-quantitative FFQ.

Urban secondary public schools in the district of Gombak in Selangor, Malaysia.

Malay adolescents aged 12 to 13 years (n 416).

The mean general cognitive ability score was 101·8 (sd 12·4). Four major dietary patterns were identified and labelled as ‘refined-grain pattern’, ‘snack-food pattern’, ‘plant-based food pattern’ and ‘high-energy food pattern’. These dietary patterns explained 39·1 % of the variance in the habitual dietary intakes of the adolescents. The refined-grain pattern was negatively associated with processing speed, which is a construct of general cognitive ability. The high-energy food pattern was negatively associated with general cognitive ability, perceptual reasoning and processing speed. Monthly household income and parents’ educational attainment were positively associated with all of the cognitive measures. In multivariate analysis, only the high-energy food pattern was found to contribute significantly towards general cognitive ability after controlling for socio-economic status.

Consumption of foods in the high-energy food pattern contributed towards general cognitive ability after controlling for socio-economic status. However, the contribution was small.

Because farmers’ markets include a variety of fruits and vegetables, shopping at farmers’ markets would likely improve diet quality among low-income consumers, as well as promote sustainable direct farm-to-consumer business models. However, not much is known about how to promote farmers’ market shopping among low-income consumers. Therefore, the purpose of the present paper was to examine barriers to and facilitators of shopping at farmers’ markets and associations between shopping at farmers’ markets and self-reported dietary behaviours (fruit and vegetable, sugar-sweetened beverage and fast-food consumption) and BMI.

Cross-sectional analyses of associations between farmers’ market shopping frequency, awareness of markets, access to markets, dietary behaviours and BMI.

Department of Social Services, Pitt County, eastern North Carolina, USA.

Between April and July 2013, Supplemental Nutrition Assistance Program (SNAP) participants (n 205) completed a quantitative survey.

Barriers to shopping at farmers’ markets included does not accept SNAP/electronic benefit transfer, out of the way and lack of transportation. Farmers’ market shopping was associated with awareness of farmers’ markets (estimate =0·18 (se 0·04), P<0·001). Fruit and vegetable consumption was positively associated with farmers’ market shopping (estimate =1·06 (se 0·32), P=0·001).

Our study is one of the first to examine SNAP participants’ farmers’ market shopping, distance to farmers’ markets and dietary behaviours. Barriers to shopping at farmers’ markets and increasing awareness of existing markets should be addressed in future interventions to increase SNAP participants’ use of farmers’ markets, ultimately improving diet quality in this high-risk group.
