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.

There is limited evidence on diet and physical activity (PA) interventions to prevent childhood over- and under-nutrition in Nigeria, particularly those with parental involvement. The aim of this qualitative cross-sectional study was to explore parents', children's, and other stakeholders' views on what might enable or hinder participation in diet and PA interventions with parental involvement, and potential intervention components likely to be feasible and acceptable. The study took place in Lagos State, Nigeria. Sixteen boys and girls aged 8–11 years in four participating schools were involved in the study. In addition, women (n = 19) and men (n = 13) aged 18–60 years took part. These included parents, teachers, school heads, community leaders, health professionals, and health or education civil servants, recruited via the participating schools, community and professional links. Data were collected in schools, homes, and places of work via one-to-one interviews and focus groups, audio-recorded with participants' consent. Topics included knowledge about a balanced diet and active living; frequency of exercise and barriers and facilitators of participation; and ideas for fostering good diet and physical activity habits. Socio-demographic data were collected orally at the start of each discussion. Thematic analysis of verbatim transcripts of the recordings was conducted. Three overarching themes were identified: (1) Active community collaboration; (2) strategies for involving families; and (3) schools as key settings for interventions. The main barriers to participation in potential interventions included poor access to clean water, safe outdoor play space, and menstrual hygiene products. Suggested solutions included increased security, infrastructure improvements using recycled materials, school gardening, and health campaigns funded by local dignitaries. Health literacy education for parents, tailored to local dialects, was considered an important potential intervention component that would engage families. The feasibility and acceptability of grassroots suggestions for intervention components and parental involvement could usefully be explored in future pilot studies. [ABSTRACT FROM AUTHOR]

Reliable data on the diet and nutritional status of African and Caribbean adults in the UK is essential for the implementation of targeted interventions to prevent diseases, and to ensure health equity. This review provides an overview of diet and nutritional status, and research and intervention priorities for West African and Caribbean adults in the UK. Cross-sectional studies that compared the two groups with their counterparts in their country of origin and/or in Europe were identified from PubMed, SCOPUS, Cochrane and CINAHL electronic databases and manual searches of bibliographies. Six eligible studies were reviewed. Reported nutrient composition focused predominantly on energy, and macronutrients, with limited information on micronutrients. Carbohydrates and fats were the main sources of energy. Low quantities of non-starch polysaccharides fibre and protein were reported. Participants from rural areas in Ghana had lower average BMI and smaller waist circumference compared to their counterparts in urban Ghana and Europe. Ghanaians in Europe consumed more alcohol and were less physically active than those in the home country. The studies measured limited nutrient composition and health-related outcomes. Studies that measure a wide range of anthropometric and clinical outcomes and key micronutrients, and use objective measures of health-related risk behaviours are needed. [ABSTRACT FROM AUTHOR]
