目标：已进行投资来改变不健康食品场所数量过多的社区的食品环境。街角商店改造是增加水果和蔬菜 (F&V) 获取渠道的一项策略。尽管文献显示取得了一定的成功，但这些干预措施的有效性仍然模棱两可。本文报告了对 Proyecto MercadoFRESCO 的评估，这是两个拉丁裔社区的街角商店改造干预措施。设计：采用了重复的横截面设计。数据按干预组分层，并通过双变量测试评估随时间的变化。建立了干预臂、时间以及干预与时间交互作用的逻辑回归模型和多元回归模型。补充分析考虑了商店内顾客的聚集和商店转换的交错。背景：美国加利福尼亚州东洛杉矶和博伊尔高地的 3 家商店被转换，5 家商店作为比较。受试者：在干预之前（n 550）和之后（n 407）对商店顾客进行了采访。结果：相对于比较商店的顾客，干预商店的顾客表现出对街角商店更有利的看法，并且在商店访问期间增加了食品和饮料的购买。商店光顾量、每周花在 F&V 食品上的百分比或每日 F&V 消费量没有发现变化。结论：与一些现有的食品环境文献一致，研究结果表明影响有限。投资应针对各种零售食品店进行多层次、全面的干预措施，而不是仅仅关注街角商店。还应采取补充政策，限制高能量、低营养食品的供应、可负担性和营销。
Objective: Investments have been made to alter the food environment of neighbourhoods that have a disproportionate number of unhealthy food venues. Corner store conversions are one strategy to increase access to fruits and vegetables (F&V). Although the literature shows modest success, the effectiveness of these interventions remains equivocal. The present paper reports on the evaluation of Proyecto MercadoFRESCO, a corner store conversion intervention in two Latino communities.Design: A repeated cross-sectional design was employed. Data were stratified by intervention arm and bivariate tests assessed changes over time. Logistic and multiple regression models with intervention arm, time and the interaction of intervention and time were conducted. Supplementary analyses account for clustering of patrons within stores and staggering of store conversions.Setting: Three stores were converted and five stores served as comparisons in East Los Angeles and Boyle Heights, California, USA.Subjects: Store patrons were interviewed before (n 550) and after (n 407) the intervention.Results: Relative to patrons of comparison stores, patrons of intervention stores demonstrated more favourable perceptions of corner stores and increased purchasing of F&V during that store visit. Changes were not detected in store patronage, percentage of weekly dollars spent on food for F&V or daily consumption of F&V.Conclusions: Consistent with some extant food environment literature, findings demonstrate limited effects. Investments should be made in multilevel, comprehensive interventions that target a variety retail food outlets rather than focusing on corner stores exclusively. Complementary policies limiting the availability, affordability and marketing of energy-dense, nutrient-poor foods should also be pursued.
