Objective: To evaluate the impact of increased availability of healthier options on purchasing of different types of vending snack products sold in English leisure (sports) centres. Design: An evaluation of an intervention using pre-post methods and interrupted time series analysis. Products within the vending machines were altered over three phases to increase the availability of healthier options, using agreed nutrition criteria – Government Buying Standards for Food and Catering Services (GBSF) for England – as a guide, as well as product availability. The primary outcome was the change in mean weekly purchased energy between the first and third phase. Secondary outcomes included changes by phase and by week in weekly number of purchases, fats, sugars and salt for all products combined and by individual product categories. Setting: Fifteen sports centres in the city of Leeds, West Yorkshire, UK. Participants: Snack products sold in eighteen vending machines. Results: Energy purchased reduced from baseline to phase 2, for all product categories combined, by 47·25 MJ (95 % CI (−61·22, −33·27)) per machine and by 279 kJ, (95 % CI (−325, −266)) per product unit. There were reductions in most nutrients purchased in all individual product categories except chocolate confectionery. Nutrients per product unit decreased for all product categories except saturated fat in chocolate confectionery. Minimal underlying trends in the baseline phase were identified, indicating changes in outcomes were likely to be due to the intervention. Conclusions: Introducing standards to increase availability of healthier snack products in vending machines is feasible without substantially affecting sales. [ABSTRACT FROM AUTHOR]

Objective: The present study aimed to evaluate the association of frequency of consuming takeaway meals and meals out with diet quality of UK adolescents.Design: The Diet Quality Index for Adolescents (DQI-A) tool was used to assess diet quality, where adolescents' food intake was based on 4d diary records obtained from the UK cross-sectional National Diet and Nutrition Survey (NDNS) rolling programme Years 1-6. Models included confounders.Setting: The DQI-A relies on three components, specifically diet quality, diversity and equilibrium, which reflect the degree of adherence of an adolescent's diet with food-based dietary guidelines.ParticipantsBritish (n 2045) adolescents aged 11-18 years.Results: Mean diet quality score for all adolescents was 20·4 % (overall DQI-A score range: -33 to 100 %). After adjusting for age, gender and equivalised household income, DQI-A% score was higher for low and moderate takeaway consumers by 7·4 % (95 % CI 5·5, 9·2; P<0·01) and 3·5 % (95 % CI 1·9, 5·1; P<0·01), respectively, v. frequent consumers. Significant differences were also observed between low, moderate and frequent takeaway consumers among all DQI-A components and sub-components (P<0·05), except for the diet adequacy sub-component (DAx). Results for frequent consumption of meals out were similar but attenuated and not statistically significant for individual components before or after adjusting for confounders.Conclusions: Frequent consumption of takeaway meals may have a negative impact on adolescents' diet quality and therefore policies to reduce the intake of takeaways should be considered in this age group.

ObjectiveIn England, standards for school meals included both foods and nutrients until 2015. School policies for packed lunches are generally food based; research is needed to determine whether these are adequate or whether a small number of nutrients would potentially improve their quality.DesignFrom dietary data obtained using a weighed dietary assessment tool, a diet quality score (DQS) for packed lunches was calculated using the number of standards met out of twenty-one (eight foods and thirteen nutrients). Multilevel regression analysis determined the foods and nutrients contributing to variation in the DQS.SettingEighty-nine primary schools across the four regions of the UK (England, Wales, Scotland and Northern Ireland).SubjectsBritish schoolchildren (n 1294), aged 8–9 years, taking a packed lunch.ResultsThe optimal model included all eight foods and seven of the thirteen nutrients, explaining 72 % of the variance in DQS. Folate, Fe and vitamin C, together with the eight food groups, explained 70 % of DQS variation.ConclusionsIdeally, policies for school packed lunches should include food-based standards plus recommendations based on a small number of nutrients.

Objective: 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.Design: 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.Setting: Fifty-four primary schools across England.Subjects: Children (n 2709) aged 6-8 years.Results: 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.Conclusions: 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. [ABSTRACT FROM AUTHOR]

ObjectiveThe present study aimed to determine whether a multi-component school-based intervention can maintain children's fruit and vegetable intake post eligibility for free school fruit and vegetables.DesignA random sample of fifty-four English primary schools was randomised to receive the 10-month intervention Project Tomato, a multi-component theory-based intervention, or the control. Each group consisted of twenty-seven schools.SettingChildren's intake of fruit and vegetables is below recommendations. The English School Fruit and Vegetable Scheme has a short-term impact on intake while children are eligible for the scheme.SubjectsDietary measurements were collected from 658 Year 2 pupils aged 7–8 years at baseline and at follow-up 20 months later.ResultsFollowing an intention to treat analysis, the intervention as delivered compared with the control had no impact on the intake of fruit and vegetables (2 g/d, 95 % CI −23, 26 g/d) or on the number of portions of fruit (0·0 portions, 95 % CI −0·3, 0·3) or vegetables (0·0 portions, 95 % CI −0·2, 0·3) consumed daily by children. Intake of fruit and vegetables at school and home dropped by ∼100 g/d and 50 g/d, respectively, between baseline and follow-up in both the intervention and control groups.ConclusionsImplementation of the intervention was low, with associated lack of impact on fruit and vegetable consumption in children. Alternatives to the delivery of an intervention by teachers and parents are needed to improve the dietary intake of primary-school children. [ABSTRACT FROM PUBLISHER]

Objective: To describe the 'Smart Lunch Box' intervention and provide details on feedback from the participants on the acceptability and usability of the intervention materials., Design: A cluster randomised controlled trial, randomised by school. English schools were stratified on percentage free-school-meals eligibility and attainment at Key Stage 2. A 'Smart Lunch Box' with supporting materials and activities on healthy eating was delivered to parents and children via schools in the intervention group. Feedback forms containing information on a total of fifteen intervention items were filled out by the parents and/or children participating in the intervention and were collected after each of the three phases of the intervention., Setting: Eighty-nine primary schools in England, Scotland, Wales and Northern Ireland, randomly selected; forty-four schools in the intervention arm., Subjects: A total of 1294 children, aged 9-10 years, took part in the trial. Of the 604 children in the intervention arm, 343 provided feedback after at least one of the three phases., Results: A median of twelve items out of a total of fifteen were used by responders. The two intervention items most likely to be used were the individual food boxes and the cooler bags. Whether a participant liked an item significantly affected whether they used it for all items except the cooler bag, fruity face and individual food boxes., Conclusions: Practical intervention items aimed at parents are likely to be used in the longer term and therefore may be appropriate for use in an intervention strategy to improve packed lunches.
