饮食是健康的重要决定因素，而购买食品是消费的关键前提。我们开始评估杂货店干预改变食品购买的有效性，并检查有效性是否根据干预成分、环境或社会经济地位而变化。我们对随机对照试验进行了系统综述（检索于2017年6月进行）。研究必须：旨在改变食品购买；在杂货店中实现（真实或模拟）；报告采购;并有最小的对照或比较干预符合我们的标准。检索、筛选、偏倚评估和数据提取采用Cochrane方法。我们按干预类型（经济、环境、交换和/或教育）对研究进行分组，以叙述的方式综合结果，并进行探索性质的比较分析。我们纳入了35项研究，涉及89项干预措施，20万名参与者和800家商店。偏倚风险是混合的。经济干预最有希望，9项研究中有8项在真实商店进行，6项在模拟环境中进行，都检测到了对购买的影响。互换干预在两项基于真实商店的研究中显得很有希望。商店环境干预显示出混合效果。单纯的教育干预在模拟环境中似乎有效，但在真实的商店中却没有效果。现有数据表明，经济干预的效果并不因社会经济地位而异，而其他干预的影响则是可变的。在我们的定性比较分析中，实际商店中的经济干预（无论环境如何）、环境和交换干预与干预所针对的≥1种食品的预期购买方向的统计显著变化相关，而实际商店中仅教育干预则没有。研究结果表明，在杂货店实施的干预措施——特别是那些操纵价格、建议交换、可能操纵物品可用性的干预措施——对购买产生了影响，并可能在改善健康的公共卫生战略中发挥作用。审查方案注册在https://www.crd.york.ac.uk/PROSPERO/，编号为CRD42017068809。
Diet is an important determinant of health, and food purchasing is a key antecedent to consumption. We set out to evaluate the effectiveness of grocery store interventions to change food purchasing, and to examine whether effectiveness varied based on intervention components, setting, or socioeconomic status. We conducted a systematic review of randomized controlled trials (search performed June 2017). Studies must have: aimed to change food purchasing; been implemented in grocery stores (real or simulated); reported purchasing; and had a minimal control or compared interventions fulfilling our criteria. Searching, screening, bias assessment, and data extraction followed Cochrane methods. We grouped studies by intervention type (economic, environmental, swaps, and/or education), synthesized results narratively, and conducted an exploratory qualitative comparative analysis. We included 35 studies representing 89 interventions, >20,000 participants, and >800 stores. Risk of bias was mixed. Economic interventions showed the most promise, with 8 of the 9 studies in real stores and all 6 in simulated environments detecting an effect on purchasing. Swap interventions appeared promising in the 2 studies based in real stores. Store environment interventions showed mixed effects. Education-only interventions appeared effective in simulated environments but not in real stores. Available data suggested that effects of economic interventions did not differ by socioeconomic status, whereas for other interventions impact was variable. In our qualitative comparative analysis, economic interventions (regardless of setting) and environmental and swap interventions in real stores were associated with statistically significant changes in purchasing in the desired direction for ≥1 of the foods targeted by the intervention, whereas education-only interventions in real stores were not. Findings suggest that interventions implemented in grocery stores—particularly ones that manipulate price, suggest swaps, and perhaps manipulate item availability—have an impact on purchasing and could play a role in public health strategies to improve health.
