Introduction: A limited number of diet, physical activity and weight management programmes suitable for UK black and Asian populations have been evaluated. We aim to coproduce 'Health Connections ' -an ambitious new intervention to support dietary and physical activity choices, and maintaining a healthier weight, tailored to the needs of black Caribbean, black African and South Asian adults. Our existing research and public engagement work suggests that the intervention should be designed to be embedded in communities and delivered by peer educators supported by health professionals., Methods and Analysis: The project is underpinned by a systems perspective that posits collective efficacy within communities, behaviour change theory and coproduction. Project activities will be conducted in three stages. Stage 1: semistructured interviews will be conducted with adults from diverse South Asian ethnic groups to understand their experiences, perspectives and intervention needs, adding to our existing data from black ethnic groups. We will synthesise the data, literature, available intervention resources and local practice, and develop the theoretical framework to codevelop intervention goals, programme theory and a draft logic model of change. Stage 2: a theorised list of potential intervention components, session content and mode/s of delivery will be explored in a modified Delphi exercise and workshop to achieve consensus on the intervention format. We will also develop prototype materials and a formal implementation plan. Stage 3: a description of the intervention will be documented., Ethics and Dissemination: The study has received ethical approval from the School of Health Research Ethics Committee, Leeds Beckett University. Information on the project aims and voluntary participation is provided in the study participation information sheet. Consent will be certified by the completion and signing of a consent form prior to data collection. Dissemination for a range of stakeholders and audiences will include publications, presentations, short films and an infographic., Competing Interests: Competing interests: MJM is a trustee of Yorkshire Dance.

Clinical Question: How effective are diet, physical activity, and behavioral interventions in treating children aged 6 to 11 years with overweight or obesity?, Bottom Line: Multicomponent behavior-changing interventions may be beneficial in achieving small, short-term reductions in body mass index (calculated as weight in kilograms divided by height in meters squared), body mass index z score, and weight in children aged 6 to 11 years. Adverse events, health-related quality of life, behavior change outcomes, and sociodemographics were poorly or inconsistently reported. Overall, the quality of the evidence was low or very low, with no evidence from lower-income countries.

Children and adolescents with overweight and obesity are a global health concern. This is an integrative overview of six Cochrane systematic reviews, providing an up-to-date synthesis of the evidence examining interventions for the treatment of children and adolescents with overweight or obesity. The data extraction and quality assessments for each review were conducted by one author and checked by a second. The six high quality reviews provide evidence on the effectiveness of behaviour changing interventions conducted in children <6 years (7 trials), 6-11 years (70 trials), adolescents 12-17 years (44 trials) and interventions that target only parents of children aged 5-11 years (20 trials); in addition to interventions examining surgery (1 trial) and drugs (21 trials). Most of the evidence was derived from high-income countries and published in the last two decades. Collectively, the evidence suggests that multi-component behaviour changing interventions may be beneficial in achieving small reductions in body weight status in children of all ages, with low adverse event occurrence were reported. More research is required to understand which specific intervention components are most effective and in whom, and how best to maintain intervention effects. Evidence from surgical and drug interventions was too limited to make inferences about use and safety, and adverse events were a serious consideration.

Background: Accurate, reliable and feasible methods of dietary intake and physical activity assessment are required to improve our understanding of the associations between energy balance-related behaviours and health., Methods: The Synchronised Nutrition and Activity Program (SNAP) was developed to enhance recall in children by integrating new and established methods of dietary intake and physical activity recall. A list of commonly consumed foods (n = 40), drinks (n = 9) and physical activities (n = 29) was used in SNAP. All foods and drinks were analysed by count (i.e., the number of times a particular food was selected), as a proxy indicator of dietary behaviours. All reported physical activities were assigned an intensity code [in metabolic equivalents (METs)] to determine minutes of moderate-vigorous activity (MVPA; ≥3 METs)., Results: Most participants completed a whole day's recall (both dietary intake and physical activities) in less than 25 min. SNAP was compared against 24-h multiple pass questionnaire and accelerometry in 121 children (aged 7-15 years old). For dietary variables, the accuracy of SNAP(™) (mean difference) was within ±1 count for the majority of food groups. The proportion of the sample with a between-method agreement within ±1 count ranged from 0.40 to 0.99. For MVPA, there was no substantial fixed or proportional bias, with a mean difference between methods (SNAP) - accelerometry) of -9 min of MVPA. Qualitatively, participants have indicated that they find SNAP easy and fun to use., Conclusions: SNAP was developed to be a simple, quick and engaging method of assessing energy balance-related behaviours at a group or population level and succeeded because it can collect a whole day's recall (dietary intake and physical activities) in less than 25 min to a reasonable and acceptable degree of accuracy., (© 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.)

The aim of the present review was to perform a systematic in-depth review of the best evidence from controlled trial studies that have investigated the effects of nutrition, diet and dietary change on learning, education and performance in school-aged children (4-18 years) from the UK and other developed countries. The twenty-nine studies identified for the review examined the effects of breakfast consumption, sugar intake, fish oil and vitamin supplementation and 'good diets'. In summary, the studies included in the present review suggest there is insufficient evidence to identify any effect of nutrition, diet and dietary change on learning, education or performance of school-aged children from the developed world. However, there is emerging evidence for the effects of certain fatty acids which appear to be a function of dose and time. Further research is required in settings of relevance to the UK and must be of high quality, representative of all populations, undertaken for longer durations and use universal validated measures of educational attainment. However, challenges in terms of interpreting the results of such studies within the context of factors such as family and community context, poverty, disease and the rate of individual maturation and neurodevelopment will remain. Whilst the importance of diet in educational attainment remains under investigation, the evidence for promotion of lower-fat, -salt and -sugar diets, high in fruits, vegetables and complex carbohydrates, as well as promotion of physical activity remains unequivocal in terms of health outcomes for all schoolchildren.
