Using a relational approach, this study investigates whether shopping close to home moderates the relationship between the proximate food environment and diet. To address this question, we develop the proximate food retail quality (PFRQ) score, an inverse-distance weighted measure of all food retailers within a resident's neighborhood that incorporates audit data of each food retailer. This study relies on data collected through 24-h dietary recalls and psychosocial surveys administered to 449 adults in two socioeconomically matched neighborhoods. Food retailer audits collected data on the availability, price, and quality of healthful foods. Seventy-one percent of study participants report conducting at least 50% of their food shopping within approximately one mile of their home. Household income and education are associated with likelihood to shop close to home, while access to a personal vehicle is not. Finally, results suggest that, for residents who shop primarily close to home, a one unit increase in proximate food retail environment score is associated with a 17.2-point increase in HEI-2010 score, a measure of overall diet quality that ranges from zero to 100. This study suggests that the food environment matters for those who use it and that a low-quality proximate food environment can amplify individual disadvantage.
本研究采用关系方法，调查了离家购物是否会缓和近食环境与饮食之间的关系。为了解决这个问题，我们开发了近食零售质量（PFRQ）评分，这是一种对居民所在社区内所有食杂店的反向距离加权衡量指标，纳入了每个食杂店的审计数据。本研究依赖于通过 24 小时膳食回忆和心理社会调查收集的数据，这些数据是在两个社会经济匹配的社区中对 449 名成年人进行的。食杂店审计收集了有关健康食品的可得性、价格和质量的数据。71%的研究参与者报告称，他们至少有 50%的食物是在离家约一英里的范围内购买的。家庭收入和教育与在家附近购物的可能性有关，而个人车辆的使用情况则没有。最后，结果表明，对于主要在家附近购物的居民，近食零售环境得分每增加一个单位，与 HEI-2010 得分的增加相关，后者是衡量整体饮食质量的指标，范围从 0 到 100。本研究表明，食环境对那些使用它的人很重要，低质量的近食环境会加剧个人劣势。
