The local retail food environment influences dietary patterns and food choices, as suggested in the literature. The lack of access to healthy food within this environment may result in unhealthy food choices which may lead to obesity and the development of non-communicable diseases. Evidence suggests that resource-poor communities may have unhealthy food environments, therefore, preventing residents from making healthy food choices. A systematic scoping review will be conducted to provide an overview of the evidence on adult food choices in association with the local retail food environment and food access in resource-poor communities.
This protocol for the scoping review was developed following the Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines and the framework process by Arksey and O'Malley. Observational studies, published from July 2005 to January 2021, will be searched and screened. Keywords and medical subject headings (MeSH) terms will be used to search several multidisciplinary databases. Two independent reviewers will screen identified articles using the selection criteria and extract data using the PRISMA-ScR checklist. Descriptive numerical and thematic analysis will be performed to evaluate and categorise quantitative and qualitative data.
Ethical approval will not be required for the review, as data from published studies will be used. The results of this scoping review will form part of a PhD thesis that will be submitted to the University of the Western Cape, South Africa. The review findings will also be presented at conferences and published in a peer-reviewed journal. OPEN SCIENCE FRAMEWORK REGISTRATION NUMBER: https://osf.io/shf93.
文献表明，当地的零售食品环境会影响饮食模式和食物选择。在这种环境中，人们可能无法获得健康食品，从而导致选择不健康的食物，这可能导致肥胖和非传染性疾病的发生。有证据表明，资源匮乏的社区可能存在不健康的食品环境，从而阻止居民做出健康的食品选择。因此，将进行系统的范围界定审查，以提供有关资源匮乏社区中成年人的食物选择与当地零售食品环境和食物获取之间关系的证据概述。
本范围界定审查的方案是按照系统评价和荟萃分析扩展的首选报告项目（PRISMA-ScR）指南以及 Arksey 和 O'Malley 的框架过程制定的。将搜索和筛选 2005 年 7 月至 2021 年 1 月发表的观察性研究。将使用关键字和医学主题词（MeSH）术语搜索多个多学科数据库。两名独立的审查员将使用选择标准筛选确定的文章，并使用 PRISMA-ScR 清单提取数据。将进行描述性数值和主题分析，以评估和分类定量和定性数据。
由于将使用已发表研究的数据，因此本次审查不需要伦理批准。本次范围界定审查的结果将作为提交给南非西开普大学的博士论文的一部分。审查结果还将在会议上展示，并发表在同行评议的期刊上。开放科学框架注册号：https://osf.io/shf93。
