Nutrient and food standards exist for school lunches in English primary schools although packed lunches brought from home are not regulated. The aim of the present study was to determine nutritional and dietary differences by lunch type.

A cross-sectional survey was carried out in 2007 assessing diet using the Child and Diet Evaluation Tool (CADET), a validated 24 h estimated food diary. The data were analysed to determine nutritional and dietary intakes over the whole day by school meal type: school meals and packed lunches.

Fifty-four primary schools across England.

Children (n 2709) aged 6–8 years.

Children having a packed lunch consumed on average 11·0 g more total sugars (95 % CI 6·6, 15·3 g) and 101 mg more Na (95 % CI 29, 173 mg) over the whole day. Conversely, children having a school meal consumed, on average, 4·0 g more protein (95 % CI 2·3, 5·7 g), 0·9 g more fibre (NSP; 95 % CI 0·5, 1·3 g) and 0·4 mg more Zn (95 % CI 0·1, 0·6 mg). There was no difference in daily energy intake by lunch type. Children having a packed lunch were more likely to consume snacks and sweetened drinks; while children having a school meal were more likely to consume different types of vegetables and drink water over the whole day.

Compared with children having a school meal, children taking a packed lunch to school consumed a lower-quality diet over the whole day, including higher levels of sugar and Na and fewer vegetables. These findings support the introduction of policies that increase school meal uptake.

To assess whether exposure to fast-food outlets around schools differed depending on socio-economic status (SES).

Binary logistic regression was used to investigate the presence and zero-inflated Poisson regression was used for the count (due to the excess of zeroes) of fast food within 1000 m and 15000 m road network buffers around schools. The low and middle SES tertiles were combined due to a lack of significant variation as the ‘disadvantaged’ group and compared with the high SES tertile as the ‘advantaged’ group. School SES was expressed using the 2011 Australian Bureau of Statistics, socio-economic indices for areas, index of relative socio-economic disadvantage. Fast-food data included independent takeaway food outlets and major fast-food chains.

Metropolitan Adelaide, South Australia.

A total of 459 schools were geocoded to the street address and 1000 m and 1500 m road network distance buffers calculated.

There was a 1·6 times greater risk of exposure to fast food within 1000 m (OR=1·634; 95 % 1·017, 2·625) and a 9·5 times greater risk of exposure to a fast food within 1500 m (OR=9·524; 95 % CI 3·497, 25·641) around disadvantaged schools compared with advantaged schools.

Disadvantaged schools were exposed to more fast food, with more than twice the number of disadvantaged schools exposed to fast food. The higher exposure to fast food near more disadvantaged schools may reflect lower commercial land cost in low-SES areas, potentially creating more financially desirable investments for fast-food developers.

The relationship between workplace absenteeism and adverse lifestyle factors (smoking, physical inactivity and poor dietary patterns) remains ambiguous. Reliance on self-reported absenteeism and obesity measures may contribute to this uncertainty. Using objective absenteeism and health status measures, the present study aimed to investigate what health status outcomes and lifestyle factors influence workplace absenteeism.

Cross-sectional data were obtained from a complex workplace dietary intervention trial, the Food Choice at Work Study.

Four multinational manufacturing workplaces in Cork, Republic of Ireland.

Participants included 540 randomly selected employees from the four workplaces. Annual count absenteeism data were collected. Physical assessments included objective health status measures (BMI, midway waist circumference and blood pressure). FFQ measured diet quality from which DASH (Dietary Approaches to Stop Hypertension) scores were constructed. A zero-inflated negative binomial (zinb) regression model examined associations between health status outcomes, lifestyle characteristics and absenteeism.

The mean number of absences was 2·5 (sd 4·5) d. After controlling for sociodemographic and lifestyle characteristics, the zinb model indicated that absenteeism was positively associated with central obesity, increasing expected absence rate by 72 %. Consuming a high-quality diet and engaging in moderate levels of physical activity were negatively associated with absenteeism and reduced expected frequency by 50 % and 36 %, respectively. Being in a managerial/supervisory position also reduced expected frequency by 50 %.

To reduce absenteeism, workplace health promotion policies should incorporate recommendations designed to prevent and manage excess weight, improve diet quality and increase physical activity levels of employees.

To demonstrate the feasibility of applying the Healthy Eating Index-2010 (HEI-2010) to the hunger relief setting, specifically by assessing the nutritional quality of foods ordered by food shelves (front-line food provider) from food banks (warehouse of foods).

This Healthy FOOD (Feedback On Ordering Decisions) observational study used electronic invoices detailing orders made by 269 food shelves in 2013 and analysed in 2015 from two large Minnesota, USA food banks to generate HEI-2010 scores. Initial development and processing procedures are described.

The average total HEI-2010 score for the 269 food shelves was 62·7 out of 100 with a range from 28 to 82. Mean component scores for total protein foods, total vegetables, fatty acids, and seafood and plant proteins were the highest. Mean component score for whole grains was the lowest followed by dairy, total fruits, refined grains and sodium. Food shelves located in micropolitan areas and the largest food shelves had the highest HEI-2010 scores. Town/rural and smaller food shelves had the lowest scores. Monthly and seasonal differences in scores were detected. Limitations to this approach are identified.

Calculating HEI-2010 for food shelves using electronic invoice data is novel and feasible, albeit with limitations. HEI-2010 scores for 2013 identify room for improvement in nearly all food shelves, especially the smallest agencies. The utility of providing HEI-2010 scores to decision makers in the hunger relief setting is an issue requiring urgent study.

Food packaging often pictures supplementary extras, such as toppings or frosting, that are not listed on the nutritional labelling. The present study aimed to assess if these extras might exaggerate how many calories† are pictured and if they lead consumers to overserve.

Four studies were conducted in the context of fifty-one different cake mixes. For these cake mixes, Study 1 compared the calories stated on the nutrition label with the calories of the cake (and frosting) pictured on the box. In Studies 2, 3 and 4, undergraduates (Studies 2 and 3) or food-service professionals (Study 4) were given one of these typical cake mix boxes, with some being told that cake frosting was not included on the nutritional labelling whereas others were provided with no additional information. They were then asked to indicate what they believed to be a reasonable serving size of cake.

Laboratory setting.

Undergraduate students and food-service professionals.

Study 1 showed that the average calories of cake and frosting pictured on the package of fifty-one different cake mixes exceed the calories on the nutritional label by 134 %. Studies 2 and 3 showed that informing consumers that the nutritional information does not include frosting reduces how much people serve. Study 4 showed that even food-service professionals overserve if not told that frosting is not included on the nutritional labelling.

To be less misleading, packaging should either not depict extras in its pictures or it should more boldly and clearly state that extras are not included in calorie counts.

The purpose of the present study was to investigate the impact of a school-based nutrition and media education intervention on the promotion of fruit and vegetable consumption to help prevent childhood obesity.

The 10-week-long intervention included sessions on nutrition education and media literacy. It also included a health communication media-based campaign workshop during which the children created posters, newsletters and video commercials related to fruits and vegetables targeted to their parents. For evaluation purposes, the study utilized a mixed-methods approach, including a quasi-experimental study (with one intervention group and one control group) and a focus group study.

Four different elementary schools in Treviso (Veneto Region of Italy) agreed to participate in the research.

The target population for the study included 10-year-old Italian children and their parents.

Data indicate that this intervention was effective for children but not for parents. Evaluation results show that the intervention was effective in significantly increasing children’s fruit and vegetable intake (P<0·05) and all psychosocial determinants (P<0·05).

The study results confirm the efficacy of a school-based health and media education intervention to address the children’s obesity issue and, in particular, to increase children’s fruit and vegetable intake. The study also opens a new perspective on the theoretical constructs investigated, because the development of ‘ability of expression’ could be considered one of the most important factors to determine the efficacy of the intervention.

To assess the relative validity and reproducibility of the semi-quantitative FFQ (SFFQ) applied in the evaluation of a community intervention study, SoL-Bornholm, for estimating food intakes.

The reference measure was a 4 d estimated food record. The SFFQ was completed two times separated by a 1-month period in order to test reproducibility.

The Capital Region and the Regional Municipality of Bornholm, Denmark.

A total of fifty-four children aged 3–9 years were enrolled in the study.

In terms of validity, the SFFQ generally overestimated intakes compared with the food records, especially for vegetables. For most intakes, the mean difference increased with increasing intake. Gross misclassification was on average higher for energy and nutrients (17 %) than for foods (8 %). Spearman correlation coefficients were significant for twelve out of fourteen intakes, ranging from 0·29 to 0·63 for foods and from 0·12 to 0·48 for energy and nutrients. Comparing the repeated SFFQ administrations, the intakes of the first SFFQ were slightly higher than those of the second SFFQ. Gross misclassification was low for most intakes; on average 6 % for foods and 8 % for energy and nutrients. Intra-class correlations were significant for all intakes, ranging from 0·30 to 0·82 for foods and from 0·46 to 0·81 for energy and nutrients.

The results indicate that the SFFQ gives reproducible estimates. The relative validity of the SFFQ was low to moderate for most intakes but comparable to other studies among children.

The present analysis aimed to observe nutritional impacts among children <5 years of age by mother’s engagement in paid employment.

Between 1996 and 2012, 21 443 children <5 years of age with diarrhoea attended the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), Dhaka Hospital. They were enrolled in the hospital-based Diarrhoeal Disease Surveillance System and their relevant information was extracted from the electronic database.

The icddr,b, Bangladesh.

The analytic sample was 19 597 children aged <5 years who had a mother aged ≤35 years with or without engagement in paid employment.

Eleven per cent of the mothers (n 2051) were currently engaged in paid employment on behalf of the family. Univariate analysis showed that children with mothers engaged in paid employment had a 1·14 times higher risk of being undernourished, a 1·20 times of higher risk of being stunted, a 1·21 times higher risk of being wasted and a 1·31 times higher risk of being underweight (risk ratios) than were children with mothers not likewise engaged. Multivariate analysis showed that such associations remained significant for stunting (1·08; 95 % CI 1·00, 1·16), wasting (1·15; 95 % CI 1·06, 1·25) and underweight (1·09; 95 % CI 1·02, 1·17) after controlling for covariates.

Mothers’ engagement in income-generating employment was associated with undernutrition in children <5 years of age in urban Bangladesh.

The link between childhood obesity and both television viewing and television advertising have previously been examined. We sought to investigate the frequency and type of food and beverage placements in children-specific television broadcasts and, in particular, differences between programme genres.

Content of five weekdays of children-specific television broadcasting on both UK (BBC) and Irish (RTE) television channels was summarized. Food and beverage placements were coded based on type of product, product placement, product use and characters involved. A comparison was made between different programme genres: animated, cartoon, child-specific, film, quiz, tween and young persons’ programming.

A total of 1155 (BBC=450; RTE=705) cues were recorded giving a cue every 4·2 min, an average of 12·3 s/cue. The genre with most cues recorded was cartoon programming (30·8 %). For the majority of genres, cues related to sweet snacks (range 1·8–23·3 %) and sweets/candy (range 3·6–25·8 %) featured highly. Fast-food (18·0 %) and sugar-sweetened beverage (42·3 %) cues were observed in a high proportion of tween programming. Celebratory/social motivation factors (range 10–40 %) were most common across all genres while there were low proportions of cues based on reward, punishment or health-related motivating factors.

The study provides evidence for the prominence of energy-dense/nutrient-poor foods and beverages in children’s programming. Of particular interest is the high prevalence of fast-food and sugar-sweetened beverage cues associated with tween programming. These results further emphasize the need for programme makers to provide a healthier image of foods and beverages in children’s television.

Little is known about the contribution of childhood socio-economic position (SEP) and social mobility to weight change. The present study evaluated the effect of family SEP during the pre-school years and social mobility on BMI between birth and adolescence.

Longitudinal. The SEP of each child’s family was classified according to an asset-based wealth index as low, medium or high. Four different categories of childhood–adolescence SEP groups were created in order to examine social mobility: low–medium/high, medium–medium, medium–high and high–high/medium. For each of these categories, BMI was tracked from birth to adolescence. Linear mixed-effects models were used to analyse the data.

Cuiabá–MT, Brazil.

A population-based cohort of children born between 1994 and 1999 was assessed between 1999 and 2000, and again between 2009 and 2011.

A total of 1716 adolescents were followed from childhood to adolescence (71·4 % of baseline). The prevalence of overweight/obesity was 20·4 % in childhood and 27·7 % in adolescence. A higher SEP in childhood was associated with a greater prevalence of overweight in adolescence. Expressive upward social mobility occurred, mainly in the lowest SEP group. There was a greater rate of change in BMI between birth and adolescence among children with a higher SEP in childhood and children who remained in the higher SEP from childhood to adolescence.

Individuals from a higher SEP in childhood and those who remained in the higher social classes showed greater rate of change in BMI. Thus, initial SEP was the major determinant of changes in BMI.

Poor adherence to recommended intake protocols is common and a top challenge for micronutrient powder (MNP) programmes globally. Identifying modifiable predictors of intake adherence could inform the design and implementation of MNP projects.

We assessed high MNP intake adherence among children who had received MNP ≥2 months ago and consumed ≥1 sachet (n 771). High MNP intake adherence was defined as maternal report of child intake ≥45 sachets. We used logistic regression to assess demographic, intervention components and perception-of-use factors associated with high MNP intake.

Four districts of Nepal piloting an integrated infant and young child feeding and MNP project.

Children aged 6–23 months were eligible to receive sixty MNP sachets every 6 months with suggested intake of one sachet daily for 60 d. Cross-sectional surveys representative of children aged 6–23 months were conducted.

Receiving a reminder card was associated with increased odds for high intake (OR=2·18, 95 % CI 1·14, 4·18); exposure to other programme components was not associated with high intake. Mothers perceiving ≥1 positive effects in their child after MNP use was also associated with high intake (OR=6·55, 95 % CI 4·29, 10·01). Perceiving negative affects was not associated; however, the child not liking the food with MNP was associated with lower odds of high intake (OR=0·12, 95 % CI 0·08, 0·20).

Behaviour change intervention strategies tailored to address these modifiable predictors could potentially increase MNP intake adherence.

To estimate factors associated with double burden of nutritional outcomes in the mother–child dyad at the household level (child stunting and/or maternal overweight).

Cross-sectional study using the Brazilian Demographic and Health Survey. Nutritional outcomes were: mother with normal weight and child with normal height; overweight mother and child with normal height; mother with normal weight and short-stature child; and overweight mother and child with short stature (double burden). The child was classified as short when height-for-age Z-score was <−2 and the mother as overweight when BMI was ≥25·00 kg/m2. Socio-economic status, environment, social vulnerability, maternal characteristics and the child’s food intake were the exposure factors. The hierarchical approach for multinomial logistic regression modelling was used to assess the associations.

National Demographic and Health Survey of Children and Women conducted in Brazil, 2006–2007.

Mother–child dyads (n 3676).

After adjustments, lower maternal educational level (OR=3·53; 95 % CI 1·33, 9·33) and inadequate household (non-masonry house; OR=2·54; 95 % CI 1·39, 4·66) were associated with the double burden of malnutrition. Mother’s short stature (OR=3·41; 95 % CI 1·76, 6·61), child’s vegetable intake on less than or equal to 4 d/week (OR=2·21; 95 % CI 1·03, 4·75) and inadequate household (non-masonry house; OR=2·29; 95 % CI 1·36, 3·87) were associated with child’s short stature. The lack of breast-feeding (OR=2·00; 95 % CI 1·07, 3·72) was associated with maternal overweight.

The present findings contribute to establishing strategies promoting health and healthy diets, by considering the growth deficit and overweight/obesity concomitantly.

To compare the BMI, body fat and waist-to-height ratio (WHtR) of stunted and non-stunted children following different growth trajectories from low socio-economic strata in Mumbai, India.

Cross-sectional, case–control study. Weight, height, skinfold thicknesses and waist circumference were measured. Information regarding the duration of breast-feeding, age at initiation of complementary feeding and income was obtained. Birth weight was obtained from records. BMI, body fat, WHtR and change in weight sd were calculated.

Children who were beneficiaries of anganwadis, Mumbai city, India.

Three hundred and thirty children aged 2–4 years were selected in each of the stunted and non-stunted groups after matching for age and sex.

After adjusting for birth weight, change in weight sd, duration of breast-feeding, age at complementary feeding initiation and income, stunted children had significantly higher body fat, WHtR and BMI than the non-stunted (P<0·01). The stunted and non-stunted children were classified based on their change in weight sd. Stunted children with no change in weight sd had higher mean body fat, BMI (P<0·01) and WHtR (P<0·05) than their non-stunted counterparts. In the catch-up growth group, stunted children had higher BMI and WHtR than the non-stunted (both P<0·001). In the catch-down growth group, stunted children had higher BMI than the non-stunted (P<0·001).

Stunting was seen to increase the tendency of conserving body fat in young children. Such a tendency, if continued during later childhood and adolescence, can increase the risk of obesity and non-communicable diseases.

The mechanism by which the home food environment (HFE) influences childhood obesity is unclear. The present study aimed to investigate the relationship between HFE and childhood obesity as mediated by diet in primary-school children.

Cross-sectional data collected from parents and primary-school children participating in the Obesity Prevention and Lifestyle Evaluation Project. Only children aged 9–11 years participated in the study. Matched parent/child data (n 3323) were analysed. Exploratory factor analysis underlined components of twenty-one HFE items; these were linked to child diet (meeting guidelines for fruit, vegetable and non-core food intakes) and measured child BMI, in structural equation modelling, adjusting for confounders.

Twenty geographically bounded metropolitan and regional South Australian communities.

School children and their parents from primary schools in selected communities.

In the initial exploratory factor analysis, nineteen items remaining extracted eight factors with eigenvalues >1·0 (72·4 % of total variance). A five-factor structure incorporating ten items described HFE. After adjusting for age, gender, socio-economic status and physical activity all associations in the model were significant (P<0·05), explaining 9·3 % and 4·5 % of the variance in child diet and BMI, respectively. A more positive HFE was directly and indirectly associated with a lower BMI in children through child diet.

The robust statistical methodology used in the present study provides support for a model of direct and indirect dynamics between the HFE and childhood obesity. The model can be tested in future longitudinal and intervention studies to identify the most effective components of the HFE to target in childhood obesity prevention efforts.

Pattern analysis has emerged as a tool to depict the role of multiple nutrients/foods in relation to health outcomes. The present study aimed at extracting nutrient patterns with respect to breast cancer (BC) aetiology.

Nutrient patterns were derived with treelet transform (TT) and related to BC risk. TT was applied to twenty-three log-transformed nutrient densities from dietary questionnaires. Hazard ratios (HR) and 95 % confidence intervals computed using Cox proportional hazards models quantified the association between quintiles of nutrient pattern scores and risk of overall BC, and by hormonal receptor and menopausal status. Principal component analysis was applied for comparison.

The European Prospective Investigation into Cancer and Nutrition (EPIC).

Women (n 334 850) from the EPIC study.

The first TT component (TC1) highlighted a pattern rich in nutrients found in animal foods loading on cholesterol, protein, retinol, vitamins B12 and D, while the second TT component (TC2) reflected a diet rich in β-carotene, riboflavin, thiamin, vitamins C and B6, fibre, Fe, Ca, K, Mg, P and folate. While TC1 was not associated with BC risk, TC2 was inversely associated with BC risk overall (HRQ5 v. Q1=0·89, 95 % CI 0·83, 0·95, Ptrend<0·01) and showed a significantly lower risk in oestrogen receptor-positive (HRQ5 v. Q1=0·89, 95 % CI 0·81, 0·98, Ptrend=0·02) and progesterone receptor-positive tumours (HRQ5 v. Q1=0·87, 95 % CI 0·77, 0·98, Ptrend<0·01).

TT produces readily interpretable sparse components explaining similar amounts of variation as principal component analysis. Our results suggest that participants with a nutrient pattern high in micronutrients found in vegetables, fruits and cereals had a lower risk of BC.

To devise a measure of diet quality from a short-form FFQ (SFFFQ) for population surveys. To validate the SFFFQ against an extensive FFQ and a 24 h diet recall.

Population-based cross-sectional survey.

East Leeds and Bolton in Northern England.

Adults (n 1999) were randomly selected from lists of those registered with a general practitioner in the study areas, contacted by mail and asked to complete the SFFFQ. Responders were sent a longer FFQ to complete and asked if they would take part in a telephone-based 24 h diet recall.

Results from 826 people completing the SFFFQ, 705 completing the FFQ and forty-seven completing the diet recall were included in the analyses. The dietary quality score (DQS), based on fruit, vegetable, oily fish, non-milk extrinsic sugar and fat intakes, showed significant agreement between the SFFFQ and the FFQ (κ=0·38, P<0·001). The DQS for the SFFFQ and the diet recall did not show significant agreement (κ=0·04, P=0·312). A number of single items on the SFFFQ predicted a ‘healthy’ DQS when calculated from the FFQ. The odds of having a healthy diet were increased by 27 % (95 % CI 9, 49 %, P<0·001) for an increase in fruit of 1 portion/d and decreased by 67 % (95 % CI 47, 79 %, P<0·001) for an increase in crisps of 1 portion/d.

The SFFFQ has been shown to be an effective method of assessing diet quality. It provides an important method for determining variations in diet quality within and across different populations.

Height is required for the assessment of growth and nutritional status, as well as for predictions and standardization of physiological parameters. To determine whether arm span, mid-upper arm and waist circumferences and sum of four skinfolds can be used to predict height, the relationships between these anthropometric variables were assessed among Ellisras rural children aged 8–18 years.

The following parameters were measured according to the International Society for the Advancement of Kinathropometry: height, arm span, mid-upper arm circumference, waist circumference and four skinfolds (suprailiac, subscapular, triceps and biceps). Associations between the variables were assessed using Pearson correlation coefficients and linear regression models.

Ellisras Longitudinal Study (ELS), Limpopo Province, South Africa.

Boys (n 911) and girls (n 858) aged 8–18 years.

Mean height was higher than arm span, with differences ranging from 4 cm to 11·5 cm between boys and girls. The correlation between height and arm span was high (ranging from 0·74 to 0·91) with P<0·001. The correlation between height and mid-upper arm circumference, waist circumference and sum of four skinfolds was low (ranging from 0·15 to 0·47) with P<0·00 among girls in the 15–18 years age group.

Arm span was found to be a good predictor of height. The sum of four skinfolds was significantly associated with height in the older age groups for girls, while waist circumference showed a negative significant association in the same groups.

To assess potential misperceptions among parents regarding the healthfulness of sugary drinks for their children.

Online survey of parents. Participants identified the categories and specific brands of sugary drinks they provided for their children. They also indicated their perceptions of sugary drink categories and brands as healthy options for children, perceived importance of on-package claims in purchase decisions and their concerns about common sugary drink ingredients.

Online market research panel.

Parents (n 982) of 2- to 17-year-olds, 46 % non-white or Hispanic.

Ninety-six per cent of parents provided on average 2·9 different categories of sugary drinks for their children in the past month. Flavoured waters, fruit drinks and sports drinks were rated as the healthiest sugary drink categories. Across all categories and brands, parents who purchased specific products rated them as significantly healthier than those who did not (P<0·05). Over half of parents reported concern about caffeine, sugar and artificial sweeteners in sugary drinks that their children consume and approximately one-third reported that on-package ingredient claims were important in their purchase decisions.

Nearly all parents provide sugary drinks for their children and many believe that some sugary drinks are healthy options for children, particularly flavoured waters, fruit drinks and sports drinks. Furthermore, many parents rely upon on-package claims in their purchase decisions. Given excessive consumption of added sugar by children in the home, there is a continuing need to address parents’ misperceptions about the healthfulness of many sugary drink products.
