简介：当地的食品环境与成人的饮食摄入和肥胖有关。然而，总体证据仍然好坏参半，需要在理论和概念上更加明确地说明社区食品店的供应情况和店内食品选择如何影响食品购买和消费。这项工作的目的是开发一个计划理论的粮食供应，从一系列的地方食品环境interventions.Methods和分析的实证证据的支持：一个系统的文献检索将遵循重复筛选和质量评估（使用有效的公共卫生实践项目工具）。然后将根据现实主义和元叙事证据综合：不断发展的标准（RAMESES）出版标准进行现实主义综合，包括透明的评估、综合和通过共识得出结论。传播：最后的综合将提出一个基于证据的食物供应计划理论，包括证据映射以展示背景因素、影响途径和潜在机制。由于缺乏经验支持的方案理论，用于目前当地的食品环境干预措施，以提高粮食供应，这种综合可以用来了解如何以及为什么干预工作，从而告知理论驱动的，以证据为基础的干预措施，以改善健康的食品选择和未来的实证工作的发展。
Introduction: Local food environments have been linked with dietary intake and obesity in adults. However, overall evidence remains mixed with calls for increased theoretical and conceptual clarity related to how availability of neighbourhood food outlets, and within-outlet food options, influence food purchasing and consumption. The purpose of this work is to develop a programme theory of food availability, supported by empirical evidence from a range of local food environment interventions.Methods and analysis: A systematic search of the literature will be followed by duplicate screening and quality assessment (using the Effective Public Health Practice Project tool). Realist synthesis will then be conducted according to the Realist And Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) publication standards, including transparent appraisal, synthesis and drawing conclusions via consensus.Dissemination: The final synthesis will propose an evidence-based programme theory of food availability, including evidence mapping to demonstrate contextual factors, pathways of influence and potential mechanisms. With the paucity of empirically supported programme theories used in current local food environment interventions to improve food availability, this synthesis may be used to understand how and why interventions work, and thus inform the development of theory-driven, evidence-based interventions to improve healthy food choice and future empirical work.
