To explore the concepts of healthy eating and to identify the barriers and facilitating factors for dietary behaviour change in adolescents.

A qualitative study involving twelve focus groups.

Two secondary schools in the district of Hulu Langat in Selangor, Malaysia.

Seventy-two adolescents aged 13–14 years.

Adolescents had some understanding regarding healthy eating and were able to relate healthy eating with the concepts of balance and moderation. The adolescents’ perceptions of healthy and unhealthy eating were based on food types and characteristics, cooking methods and eating behaviours. Facilitators for healthy eating were parents’ control on adolescents’ food choices, feeling concern about own health and body, being influenced by other’s health condition, and knowledge of healthy or unhealthy eating. On the other hand, barriers for healthy eating were the availability of food at home and school, taste and characteristics of foods, and lack of knowledge on healthy or unhealthy foods.

The findings contribute to a better understanding of the adolescents’ concept of healthy eating, as well as the facilitators and barriers to practising healthy eating. Future interventions should include a method of promoting the immediate benefits of healthy eating, the way to cope with environmental barriers for healthy eating, and increasing the availability of healthy food choices at home and in the school environment. The health and nutrition education programmes should also focus on educating parents, as they can be role models for adolescents to practise more healthful behaviours.

Emigrants face a high level of food insecurity. There is a wide research gap in the domain of identifying the determinants and problems of dietary acculturation in the context of emigrant students. This article attempts to study the factors affecting the dietary acculturation of African emigrant students in India.

For conducting a first-of-its-kind study for African emigrant students in India, we used field survey method, and the primary data were collected using a pre-structured questionnaire.

This was a field survey conducted in Punjab (a state of India).

One hundred and twenty African emigrant students participated in the survey.

Results of logistic regression indicated that food awareness (P = 0·027) and food suitability (P = 0·043) were the major determinants of dietary acculturation. Lack of familiarity and lack of proximity to food access points are the major problems faced by the African emigrant students. African emigrant students prepared for dietary acculturation largely only after coming to India. There is a significant positive correlation (P = 0·013) between problems faced by the respondents and tendency to prepare for acculturation after coming to India.

Information regarding local food environment plays a significant role in dietary acculturation. There is a pertinent need to educate emigrant students regarding food availability and access by developing suitable educational content.

To examine associations between protein intake per day and at different meals and skeletal muscle mass declines.

Two-year prospective cohort study among older community dwellers.

National Institute for Longevity Sciences–Longitudinal Study of Aging (NILS-LSA) in Japan.

Older men (n 292) and women (n 363) aged 60–87 years who participated in the baseline (2006–2008) and follow-up studies (2008–2010) of NILS-LSA and did not exhibit low skeletal muscle mass at baseline. Muscle mass was assessed using dual-energy X-ray absorptiometry at baseline and follow-up. Low muscle mass was defined as skeletal muscle mass index <7·0 kg/m2 for men and <5·4 kg/m2 for women at follow-up. Daily protein intake and protein intake at each meal were calculated from 3 d dietary records at baseline and sex-stratified tertiles were determined.

Mean (sd) protein intake at breakfast, lunch and dinner was 22·7 (7·8), 26·7 (9·3) and 37·4 (10·5) g for men and 19·3 (6·3), 23·2 (7·3) and 28·5 (7·0) g for women, respectively. After adjusting for age, baseline skeletal muscle mass and other confounders in logistic modelling, greater total protein intake was associated with lower prevalence of skeletal muscle mass decline among men at follow-up (P = 0·024). Particularly, the OR (95 % CI) for high lunchtime protein intake was low (0·11 (0·02, 0·61); P = 0·01). No significant association between total protein intake and prevalence of skeletal muscle mass decline was found among women.

High total protein intake, particularly at lunchtime, is associated with retention of skeletal muscle mass in men.

To assess availability, variety, price and quality of different food products in a convenience sample of supermarkets in Germany and the USA.

Cross-sectional study using an adapted version of the Bridging the Gap Food Store Observation Form.

Information on availability, quality, price and variety of selected food products in eight German and seven US supermarkets (discount and full service) was obtained and compared by country.

A general tendency for lower prices of fruits and vegetables in Germany was observed, while produce quality and variety did not seem to differ between countries, with the exception of the variety of some vegetables such as tomatoes. Chips and cereals did not differ significantly in variety nor price. In both countries, high energy-dense foods were lower in energy costs than lower energy-dense foods.

The influence of food prices and availability on consumption should be further explored, including the impact of country differences.

We investigated short- and long-term indicators of malnutrition and diet before and after the community-based ‘Breaking the Cycle of Poverty’ multidisciplinary intervention.

A historically and geographically controlled study using data collected in 2013 and 2016. We compared the prevalence of short-term indicators (anaemia, breast-feeding duration and minimum dietary diversity) and long-term indicators (stunting and wasting) in exposed communities at two time points. We then compared these factors in geographic areas exposed or not exposed to intervention. We conducted logistic regression analyses on the 2016 sample to measure associations between living in intervention communities and child growth indicators.

Berd region, a chronic conflict zone near the north-eastern border of Armenia and Azerbaijan.

Children aged 6 months to 6 years.

Analyses included data from 2013 comprising 382 children, and data from 2016 comprising 348 children living in communities where the programme was implemented, and 635 children from unexposed communities. Anaemia prevalence in exposed communities was significantly lower in 2016 v. 2013 (10·9 v. 19·1 %, P < 0·01). Minimum dietary diversity (79·0 v. 68·1 %, P < 0·001) and breast-feeding duration (13·0 v. 11·5 months, P < 0·002) were significantly improved in exposed communities. Prevalences of stunting (11·5 v. 10·2 %, P = 0·57) and wasting (4·8 v. 2·0 %, P = 0·07) were not significantly different. Odds of anaemia were significantly lower (OR = 0·24, 95 % CI 0·16, 0·36) in intervention communities.

Exposure to a community-based multidisciplinary intervention reduced the rate of anaemia and improved dietary indicators.

To make a tentative assessment of the consumption of cassava in three countries in South-east Asia and the cyanogenic potential (CNp) of the crop as a possible food safety issue.

We used data from the Ministry of Health in Vietnam and Statistics Authorities in Indonesia and Philippines (mean household consumption per province) to assess cassava consumption. Conversions of units were needed to facilitate the comparison of cassava consumption between countries. The most up-to-date data available regarding both cassava consumption and the CNp of cassava grown in the respective countries were assessed.

Vietnam, Indonesia and Philippines.

Respondents from provinces in Vietnam (nineteen), Indonesia (thirty-three) and Philippines (eighty-one) were asked to complete a recall questionnaire detailing either the previous 24-h’ or the 7-d’ cassava consumption.

Among the three countries, available data indicated that the highest median cassava-consumption figures percapita were from Indonesia and the Philippines (9·01 and 7·28 g/capita per d, respectively), with Vietnam having the least (1·14 g/capita per d). Published information regarding the CNp of cassava in the three countries was limited.

While the findings of the present study are somewhat limited by a lack of available information regarding both the extent of cassava consumption and the CNp of cassava consumed in the three countries, it appears likely that cyanogen intake arising from cassava consumption among the three countries exceeds the FAO/WHO Provisional Maximum Tolerable Daily Intake, although any risk to public health appears limited to a minority of provinces in each country.

To investigate the effects of providing free fruit and snack vegetables at a university on students’ fruit intake, snack vegetable intake and total vegetable intake.

Free fruit and raw snack vegetables (e.g. bite-sized tomatoes) were provided in a stand in the form of a miniature wooden house located in the central hall of the university’s main building, which students regularly pass through on their way to lectures and the cafeteria. Three interventions tested with a pre-test/post-test design were performed. In these three interventions, small changes to the appearance of the stand were made, such as placing potted plants around it. Demographic characteristics and fruit and vegetable intakes were assessed with questionnaires.

A Dutch university of applied science.

Intervention 1 included 124 students; Intervention 2 included ninety-two students; Intervention 3 included 237 students.

Longitudinal linear regression analyses showed that post-test snack vegetable intake was consistently higher compared with pre-test. In the three interventions, post-test snack vegetable intakes were between 11 and 14 g/d higher than at the pre-test, which is comparable to three bite-sized tomatoes. No differences in fruit intake or total vegetable intake were found. Subgroup analyses showed that, in all three interventions, students with the lowest pre-test fruit intake and total vegetable intake reported the largest increase in fruit intake and snack vegetable intake after the interventions.

Providing free fruit and vegetables to students at their university might be beneficial for those with low habitual intakes.

The present study aimed at surveying the nutritional quality of prepacked biscuits and sweet snacks sold on the Italian market, and at identifying whether the product type and other information reported on the pack could discriminate the overall quality of products analysed.

Data on energy, nutrient and salt content of the products from two different categories of prepacked sweet cereal products (i.e. biscuits and sweet snacks) were collected from thirteen retailers present on the Italian market. Based on the product type, nutrition and health claim (NHC) and gluten-free (GF) declaration, a comparison of nutrient profile within each category was performed.

This work is part of the Food Labelling of Italian Products (FLIP) study that aims at systematically investigating the overall quality of the prepacked foods sold on the Italian market.

A total of 1290 products were analysed (63 % biscuits and 37 % sweet snacks). After comparing different product types within each category, a high intra-type product variability was evidenced, which was more pronounced for biscuits. Overall, NHC-carrying products seemed to have a better nutrition profile than those without claims, except for salt content. Conversely, a comparison between GF and gluten-containing products did not show consistent results within the two categories analysed.

Due to the high intra-type variability within each category, the different characteristics and regulated information reported on the pack do not seem to be a clear marker of the overall nutritional quality of biscuits and snacks.

Globally, China is among the ‘saltiest’ nations. In order to support current nationwide salt reduction initiatives, we investigated Chinese consumers’ knowledge, beliefs and behaviours related to salt intake and salt reduction.

A cross-sectional face-to-face survey was carried out, focusing on salt knowledge, beliefs and behaviours related to salt intake and salt reduction, perceptions of salt reduction responsibility and support for different national strategies.

The survey was carried out in China mainland.

Consumers (n 2444) from six of seven major geographical regions in China participated in the survey. After data cleaning, a sample of 2430 was included in the final analysis.

A majority of Chinese consumers believed that salt added during home cooking was the biggest contributor to their salt intake. Knowledge gaps existed in the awareness of salt hidden in certain foods and flavouring products. Chinese consumers in general were interested in lowering their salt intake. They were aware of salt reduction tools, but the adoption level was low. Consumers expressed strong support for promotion of salt-restriction spoons and public education, but not fiscal policies (e.g. salt-related tax or subsidies). In terms of individual differences, education status demonstrated a substantial impact on salt reduction knowledge and behaviour.

There is still big room to ‘shake’ Chinese consumers’ salt habit. The present study provides important evidence and consumer insights to support China’s efforts to meet its salt reduction targets.

To examine the relationship between household food insecurity (FI) and children’s involvement in family meal choices and food preparation, used as proxies for children’s food skills, and to explore gender differences within these associations.

Households were classified as food-secure or food-insecure using the six-item, short-form Household Food Security Survey Module. Children’s involvement in family meal choices and food preparation were treated as proxies for children’s food skills. Mixed-effects multinomial logistic regression models were used.

Public schools in Nova Scotia, Canada.

5244 children in the fifth grade (10–11 years old) participating in the Children’s Lifestyle and School Performance Study (CLASS).

Most children reported being involved in family meal choices or food preparation at least weekly (74 and 68 %). The likelihood of helping choose family meals once a week was 33 % lower among girls from food-insecure households compared to girls from food-secure households. No differences in boys’ involvement in family meal choices were observed according to household FI status. Boys from food-insecure households were 65 % more likely than boys from food-secure households to assist with food preparation/cooking four times per week. No differences in girls’ involvement in food preparation were observed according to household FI status.

Findings support that household FI is not due to a lack of food skills but most likely due to inadequate access to resources. This supports the call for upstream policies targeting the structural issues underpinning household FI such as low income.

Maternal vitamin D level in pregnancy may have implications for both the mother and fetus. Deficiency of vitamin D has been linked to several pregnancy complications and fetal skeletal health. Smoking has been associated with reduced serum level of the vitamin D metabolite, 25-hydroxyvitamin D (25(OH)D).

A nested case–control study within the Finnish Maternity Cohort, a population-based cohort which includes first-trimester sera from 98 % of pregnancies in Finland since 1987. The selection consisted of women with uncomplicated pregnancies. We studied serum concentration of 25(OH)D in 313 non-smoking and forty-six self-reported smoking pregnant women.

We hypothesize that pregnant smokers may have an increased risk of low 25(OH)D levels especially during winter months.

A control group from an unpublished pregnancy complication study consisting of 359 uncomplicated pregnancies. Individuals who reported that they do not smoke were considered ‘non-smokers’ (n 313) and those who reported continued smoking after the first trimester of pregnancy were considered ‘smokers’ (n 46).

Smokers had significantly lower levels of 25(OH)D irrespective of sampling time (P<0·0001). Furthermore, during the low sun-exposure season, only 14 % of smokers met the guideline level of 40 nmol/l for serum 25(OH)D in comparison with 31 % of non-smokers.

Expectant mothers who smoke have an increased risk of vitamin D deficiency during low sun-exposure months in northern regions. Further studies are needed to assess the associated risks for maternal and fetal health as well as possible long-term implications for the infant.

To evaluate the association between weight status and food insecurity of children living in social vulnerability who are beneficiaries of a food assistance programme (FAP).

Cross-sectional study.

From all children benefiting from the FAP in the municipality, 30 % were mapped in forty-seven distribution points. Their weight status was evaluated using BMI-for-age and food insecurity was determined with the Brazilian Food Insecurity Scale. Socio-economic data of the participants were collected using regular questionnaires. The main outcome measure was obesity.

To be a beneficiary of the FAP, a family must have a child aged 24–96 months and receive less than half a minimum wage per capita. Participating families receive 1 litre of whole milk per day.

In all, 1487 children had BMI-for-age and food insecurity data. Of these children, 376 (25·3 %) had excess weight, of whom 164 (11·0 %) presented with obesity, and only twenty-seven (1·8 %) were underweight; 76 % of the families had some degree of food insecurity. Multivariable analysis revealed no overall association between household food insecurity and weight status. In the specific comparison, children living in severe food insecurity were less likely to present obesity than those children living in food security (prevalence ratio = 0·60; 95 % CI 0·38, 0·96; P = 0·03).

In a socially vulnerable population that participates in a FAP, there was no overall association between food insecurity and weight status in children, a result which is similar to what is observed in more developed contexts.

To investigate the association of folic acid (FA) supplementation with birth weight, the risk of small for gestational age (SGA) and low birth weight (LBW) in singleton and twin pregnancy.

A population-based cross-sectional survey.

Twenty counties and ten districts in Shaanxi Province of northwestern China, 2013.

28 174 pregnant women with their infants, covering 27 818 single live births and 356 twin live births.

The prevalence of FA supplementation in singletons and twins was 63·9 and 66·3 %. The mean birth weight was 3267 (sd 459·1) g, 2525 (sd 534·0) g and 2494 (sd 539·5) g; the prevalence of SGA was 14·3, 51·4 and 53·4 %; the prevalence of LBW was 3·4, 42·4 and 46·6 % among singleton, twin A and twin B, respectively. Compared with non-users, women with FA supplementation were (β 17·3, 95 % CI 6·1, 28·4; β 166·3, 95 % CI 69·1, 263·5) associated with increased birth weight, lower risk of SGA (OR 0·85, 95 % CI 0·80, 0·92; OR 0·45, 95 % CI 0·30, 0·68) and LBW (OR 0·82, 95 % CI 0·71, 0·95; OR 0·50, 95 % CI 0·33, 0·75) in singletons and twins, and more prominent effects in twins. Moreover, there were significant interactions between FA supplementation and plurality on birth weight, SGA and LBW.

The present study suggests the association of periconceptional 0·4 mg/d FA supplementation with increased birth weight and reduced risk of SGA and LBW in both singletons and twins, and this association may be more prominent in twins.

To determine whether there were changes in the prevalence or healthiness of products carrying claims post-implementation of Standard 1.2.7: Nutrition, Health and Related Claims in the Australia New Zealand Food Standards Code.

Observational survey of claims on food packages in three categories: non-alcoholic beverages, breakfast cereals and cereal bars. Nutrient profiling was applied to products to determine their eligibility to carry health claims under Standard 1.2.7. The Standard came into effect in 2013. The proportion of products carrying claims and the proportion of those not meeting the nutrient profiling criteria were calculated. A comparative analysis was conducted to determine changes between 2011 and 2016.

Three large metropolitan stores from the three major supermarket chains in Sydney, Australia were surveyed in 2011 and 2016.

All claims on all available products in 2016 (n 1737). Nutrition composition and ingredients were collected from the packaging.

Overall in 2016, 76 % of products carried claims and there were 7367 claims identified in the three food categories. Of products in 2016 with health claims, 34 % did not meet nutrient profiling criteria. These may breach Standard 1.2.7. Comparison of 2011–2016 showed a significant increase in the number of products carrying claims (66 v. 76 %, P < 0·001).

The proportion of products carrying claims that do not meet nutrient profiling and consumers’ tendency to infer health benefits from nutrition content claims warrants the regulation of all claims using the nutrient profiling. This will ensure consumers are not misled by claims on unhealthy food products.

In the present study, we aimed to compare anthropometric indicators as predictors of mortality in a community-based setting.

We conducted a population-based longitudinal study nested in a cluster-randomized trial. We assessed weight, height and mid-upper arm circumference (MUAC) on children 12 months after the trial began and used the trial’s annual census and monitoring visits to assess mortality over 2 years.

Niger.

Children aged 6–60 months during the study.

Of 1023 children included in the study at baseline, height-for-age Z-score, weight-for-age Z-score, weight-for-height Z-score and MUAC classified 777 (76·0 %), 630 (61·6 %), 131 (12·9 %) and eighty (7·8 %) children as moderately to severely malnourished, respectively. Over the 2-year study period, fifty-eight children (5·7 %) died. MUAC had the greatest AUC (0·68, 95 % CI 0·61, 0·75) and had the strongest association with mortality in this sample (hazard ratio = 2·21, 95 % CI 1·26, 3·89, P = 0·006).

MUAC appears to be a better predictor of mortality than other anthropometric indicators in this community-based, high-malnutrition setting in Niger.

Electronic Benefit Transfer (EBT) placement at farmers’ markets can reduce access disparities for low-income consumers. However, resources needed to operate EBT programs may challenge markets’ business models. A conceptual model of factors impacting EBT program success was developed from literature, and an exploratory study conducted to assess the impact of model variables on market EBT sales.

Annual EBT sales data were obtained for all Hawai‘i farmers’ markets with EBT programs (n 22). Key informant interviews (n 19), along with records review, were performed to gather data on model variables. Exploratory analysis was conducted to estimate the impact of individual model variables on EBT sales.

Farmers’ markets accepting EBT in the state of Hawai‘i.

Market managers and EBT program partners (n 19).

Markets engaging in community partnerships $\left( {{\mkern 1mu} {\mkern 1mu} \Delta \overline x = \$ 852} \right)$, consumer education $\left( {{\mkern 1mu} {\mkern 1mu} \Delta \overline x = \$ {\rm{598}}} \right)$, social media promotion $\left( {{\mkern 1mu} {\mkern 1mu} \Delta \overline x = \$ {\rm{732}}} \right)$ or EBT incentives $\left( {{\mkern 1mu} {\mkern 1mu} \Delta \overline x = \$ {\rm{5}}0{\rm{9}}} \right)$ averaged higher sales than markets not reporting these practices. Sales increased by $3 for every ten additional SNAP-participating households and decreased by $35 for each competing EBT-accepting supermarket, grocery or farmers’ market within the market’s access area. Sales increased by $137/vendor for each additional hour/week the market was open.

Factors suggested by the model, particularly community engagement and partnership, marketing methods, consumer base and competition for EBT sales in the market area substantively affected EBT sales. Assessing these factors may identify markets with the greatest chance of EBT success and suggest ways to strengthen struggling EBT programs.

To estimate food insecurity (FI) prevalence among UK adults and investigate associations with socio-demographic characteristics, diet and health.

Weighted cross-sectional survey data. FI was measured using the USDA Adult Food Security Survey Module. Data were analysed using adjusted logistic regression models.

United Kingdom.

2551 participants (aged 18–64 years); sub-sample (n 1949) used to investigate association between FI and overweight.

FI prevalence was 24·3 %. Higher odds of FI were observed among participants who reported that making ends meet was difficult v. easy (OR 19·76, 95 % CI 13·78, 28·34), were full-time students v. non-students (OR 3·23, 95 % CI 2·01, 5·18), had low v. high education (OR 2·30, 95 % CI 1·66, 3·17), were male v. female (OR 1·36, 95 % CI 1·01, 1·83) and reported their ethnicity as mixed (OR 2·32, 95 % CI 1·02, 5·27) and white other (OR 2·04, 95 % CI 1·04, 3·99) v. white British. Odds of FI were higher in participants living with children v. alone, especially in single-parent households (OR 2·10, 95 % CI 1·19, 3·70). Odds of FI decreased per year of increase in age (OR 0·95, 95 % CI 0·94, 0·96) and were lower in participants not looking for work v. full-time employed (OR 0·60, 95 % CI 0·42, 0·87). Food insecure v. food secure adults had lower odds of consuming fruits (OR 0·59, 95 % CI 0·47, 0·74) and vegetables (OR 0·68, 95 % CI 0·54, 0·86) above the median frequency, and higher odds for fruit juice (OR 1·39, 95 % CI 1·10, 1·75). Food insecure v. food secure adults had higher odds of reporting unhealthy diets (OR 1·65, 95 % CI 1·31, 2·10), poor general health, (OR 1·90, 95 % CI 1·50, 2·41), poor mental health (OR 2·10, 95 % CI 1·64, 2·69), high stress (OR 3·15, 95 % CI 2·42, 4·11) and overweight (OR 1·32, 95 % CI 1·00, 1·75).

FI prevalence was high and varied by socio-demographic characteristics. FI was associated with poorer diet and health.

To assess the Na content and price of bread available in bakeries in the city of Maputo in 2018 and describe trends since 2012.

Cross-sectional evaluation of bread sold in twenty bakeries in the city of Maputo. Three loaves of white and three loaves of brown bread were collected from each bakery when available, and Na contents were quantified by flame photometry. To assess trends, samples of white bread collected in 2012 and analysed using the same methodology were compared with samples of white bread collected in 2018 from the same bakeries.

City of Maputo, capital of Mozambique.

In 2018, the mean (range) Na content in mg/100 g of white and brown breads were 419·1 (325·4–538·8) and 389·8 (248·0–609·0), respectively. Non-compliance with Na targets in bread according to the South African regulation (<380 mg/100 g) was observed in 70 % of white and 43 % of brown bread samples. A total of twelve bakeries had samples evaluated in both 2012 and 2018; among these, the mean Na content in white bread decreased by just over 10 % – the mean difference (95 % CI) was 46·6 mg/100 g (1·7, 91·5); and there was a significant increase of 3·7–5·4 meticais in the mean price per 100 g of white bread.

The Na content of bread available in bakeries in the city of Maputo decreased in recent years despite the absence of a specific regulation in Mozambique.

The objective was to examine the association between symptoms of maternal mental health problems and child diet and nutritional status in South Kivu, Democratic Republic of Congo.

Maternal depression and anxiety symptoms were measured by the Hopkins Symptom Checklist-25 (HSCL-25), and post-traumatic stress was measured by the Harvard Trauma Questionnaire (HTQ). Participants were classified as having high psychological distress if their mean item score was in the upper quartile of both measures. Dependent variables included child dietary diversity, meal frequency, height-for-age z score (HAZ), weight-for-age z score (WAZ), weight-for-height z score (WHZ), stunting and underweight. Bivariate and multivariate regression analyses were conducted.

The study was nested in a larger quasi-experimental study evaluating Jenga Jamaa II, a food and nutrition assistance project in Uvira and Fizi territories.

In total, 812 mother–child pairs participated. Children ranged from 2·6 to 5·6 years of age.

HSCL-25 (ß: 0·18, P < 0·05) and HTQ (ß: 0·19, P < 0·05) were statistically significantly associated with higher dietary diversity scores, and all maternal mental health measures were associated with higher meal frequency (HSCL-25: ß: 0·13, P = 0·001; HTQ: ß: 0·12, P = 0·001; high distress: ß: 0·15, P < 0·05) and consumption of at least three meals/snacks per day (HSCL-25: OR: 2·06, HTQ: OR: 1·93, high distress: OR: 2·68, P < 0·001 for all). No significant associations were found with HAZ, WAZ, WHZ, stunting or underweight indicators.

More severe symptoms of maternal mental health problems were positively associated with child diet, but not anthropometry indicators. More research is needed to understand the role of maternal mental health in child feeding practices in food insecure and resource-poor settings.
