'Health Connections': Study protocol for the development of a coproduced, community-based diet, physical activity, and healthy weight intervention for UK black and Asian adults

Abstract

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.
