Complex food retail settings, where multiple food retail outlets operate in close proximity are common. Despite their ubiquity, there remains a significant knowledge gap regarding healthy food retail interventions implemented within these settings. Furthermore, understanding the factors affecting the implementation of interventions in these settings remains limited. This systematic review aimed to (1) identify and describe complex food retail settings where interventions were implemented to promote the healthiness of foods purchased, (2) synthesise the evidence on the effectiveness of the interventions implemented, and (3) identify enablers and barriers to the implementation of the interventions in these settings. Four databases, namely, MEDLINE Complete, Global Health, Embase, and Business Source Complete, were searched until December 2022. The Effective Public Health Practice Project quality assessment tool was used. Six studies reported on the implementation of interventions promoting healthy food purchases across multiple food retail outlets. Three studies each described two complex food retail settings: university and hospital. Interventions including promotion and promotion plus price improved the healthiness of foods purchased. There was limited description of institutional food policies, conceptual frameworks, formative research, or evaluation outcomes to inform the implementation of interventions in these settings. No study analysed enablers and barriers to the implementation of interventions. No study identified their settings as complex food retail settings. There is limited evidence describing complex food retail settings, their impact on intervention effectiveness, and associated enablers or barriers. Investigating factors influencing the effectiveness of interventions implemented within complex food retail settings is critical to support their implementation at scale.
复杂的食品零售环境中，多个食品零售点通常毗邻经营。尽管这些环境很常见，但对于在这些环境中实施的健康食品零售干预措施，仍存在着显著的知识空白。此外，对于影响这些环境中干预措施实施的因素的理解仍然有限。本系统评价旨在：(1) 确定和描述实施干预措施以促进购买食品健康性的复杂食品零售环境；(2) 综合实施干预措施的效果证据；(3) 确定在这些环境中实施干预措施的促进因素和障碍。四个数据库，即 MEDLINE Complete、全球健康、Embase 和商业来源完整，被搜索到 2022 年 12 月。使用有效公共卫生实践项目质量评估工具。六项研究报告了在多个食品零售点实施促进健康食品购买的干预措施的情况。每三研究分别描述了两个复杂的食品零售环境：大学和医院。包括促销和促销加价格在内的干预措施改善了购买食品的健康性。这些研究很少描述机构食品政策、概念框架、形成性研究或评估结果，以告知在这些环境中实施干预措施。没有研究分析实施干预措施的促进因素和障碍。没有研究将其环境确定为复杂的食品零售环境。有有限的证据描述了复杂的食品零售环境、它们对干预效果的影响以及相关的促进因素或障碍。调查影响复杂食品零售环境中实施的干预措施效果的因素对于支持这些干预措施在大规模实施至关重要。
