改善健康食品零售的政策已被认为是减少与饮食有关的健康差距的潜在手段。修订后的2014年明尼阿波利斯主食条例规定了健康主食的最低库存标准。本研究的目的是研究零售商遵守的政策，以及是否遵守不同的邻里和商店的特点。方法在这项自然实验中，每年在明尼阿波利斯，明尼苏达州和一个比较城市（圣保罗，明尼苏达州）的155家小型/非传统商店进行条例前和条例后（2014-2017）的审计。10个产品类别的合规措施包括：（1）满足≥ 8个类别的要求;（2）10分制（满足每个要求一分）;（3）携带每个类别中的任何项目。店铺特征包括店铺规模和所有权状况。社区特征包括人口普查区的社会经济地位和低收入/低访问状态。分析是在2018年进行的。结果明尼阿波利斯和圣保罗的所有依从性指标从政策实施前到实施后都有所增加;明尼阿波利斯的增加仅在携带每个类别中的任何项目时更大（p < 0.01）。在明尼阿波利斯，公司（与独立）商店通常更符合要求。邻里特征无差异。结论总体趋势表明，明尼阿波利斯商店之间的广泛运动，以提供最低水平的主食。公司商店的增幅更大。这些趋势并不表明在遵守方面存在着社区一级的差异。研究登记NCT 02774330，回顾性登记于2016年5月17日。
Background Policies to improve healthy food retail have been recognized as a potential means of reducing diet-related health disparities. The revised 2014 Minneapolis Staple Foods Ordinance instituted minimum stocking standards for healthy, staple foods. The objective of this study was to examine retailer compliance with the policy, and whether compliance varied by neighborhood and store characteristics. Methods In this natural experiment, audits were conducted annually pre- and post-ordinance (2014-2017) in 155 small/nontraditional stores in Minneapolis, MN and a comparison city (St. Paul, MN). Compliance measures for 10 product categories included: (1) met requirements for >= 8 categories; (2) 10-point scale (one point for each requirement met); and (3) carried any item in each category. Store characteristics included store size and ownership status. Neighborhood characteristics included census-tract socioeconomic status and low-income/low-access status. Analyses were conducted in 2018. Results All compliance measures increased in both Minneapolis and St. Paul from pre- to post-policy; Minneapolis increases were greater only for carrying any item in each category (p < 0.01). In Minneapolis, corporate (vs. independent) stores were generally more compliant. No differences were found by neighborhood characteristics. Conclusions Overall trends suggest broad movement among Minneapolis stores towards providing a minimum level of staple foods. Increases were greater in corporate stores. Trends do not suggest neighborhood-level disparities in compliance. Study registration NCT02774330, retrospectively registered May 17, 2016.
