BACKGROUND
Purchases at small/non-traditional food stores tend to have poor nutritional quality, and have been associated with poor health outcomes, including increased obesity risk The purpose of this study was to examine whether customers who shop at small/non-traditional food stores with more health promoting features make healthier purchases.
METHODS
In a cross-sectional design, data collectors assessed store features in a sample of 99 small and non-traditional food stores not participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Minneapolis/St. Paul, MN in 2014. Customer intercept interviews (n = 594) collected purchase data from a bag check and demographics from a survey. Store measures included fruit/vegetable and whole grain availability, an overall Healthy Food Supply Score (HFSS), healthy food advertisements and in-store placement, and shelf space of key items. Customer nutritional measures were analyzed using Nutrient Databases System for Research (NDSR), and included the purchase of ≥1 serving of fruits/vegetables; ≥1 serving of whole grains; and overall Healthy Eating Index-2010 (HEI-2010) score for foods/beverages purchased. Associations between store and customer measures were estimated in multilevel linear and logistic regression models, controlling for customer characteristics and store type.
RESULTS
Few customers purchased fruits and vegetables (8%) or whole grains (8%). In fully adjusted models, purchase HEI-2010 scores were associated with fruit/vegetable shelf space (p = 0.002) and the ratio of shelf space devoted to healthy vs. less healthy items (p = 0.0002). Offering ≥14 varieties of fruit/vegetables was associated with produce purchases (OR 3.9, 95% CI 1.2-12.3), as was having produce visible from the store entrance (OR 2.3 95% CI 1.0 to 5.8), but whole grain availability measures were not associated with whole grain purchases.
CONCLUSIONS
Strategies addressing both customer demand and the availability of healthy food may be necessary to improve customer purchases.
TRIAL REGISTRATION
ClinialTrials.gov: NCT02774330 . Registered May 4, 2016 (retrospectively registered).
背景
在小型/非传统食品店购买的食品往往营养质量较差，且与健康状况不佳有关，包括肥胖风险增加。本研究的目的是调查在具有更多促进健康功能的小型/非传统食品店购物的顾客是否会购买更健康的食品。
方法
采用横断面设计，数据收集者对明尼阿波利斯/圣保罗市99家未参与妇女、婴儿和儿童特别补充营养计划（WIC）的小型和非传统食品店进行了店铺特征评估。顾客拦截访谈（n = 594）通过检查购物袋收集购买数据，并通过调查收集人口统计学数据。店铺测量指标包括水果/蔬菜和全谷物的供应情况、整体健康食品供应得分（HFSS）、健康食品广告及店内摆放位置，以及关键商品的货架空间。顾客营养指标采用研究用营养数据库系统（NDSR）进行分析，包括购买≥1份水果/蔬菜；≥1份全谷物；以及所购食品/饮料的整体健康饮食指数-2010（HEI-2010）得分。在控制顾客特征和店铺类型的多水平线性和逻辑回归模型中估计店铺指标与顾客指标之间的关联。
结果
很少有顾客购买水果和蔬菜（8%）或全谷物（8%）。在完全调整模型中，购买的HEI-2010得分与水果/蔬菜货架空间（p = 0.002）以及健康商品与不太健康商品的货架空间比例（p = 0.0002）相关。提供≥14种水果/蔬菜品种与农产品购买相关（OR 3.9，95% CI 1.2 - 12.3），从店铺入口能看到农产品也与之相关（OR 2.3，95% CI 1.0至5.8），但全谷物供应指标与全谷物购买无关。
结论
可能需要同时针对顾客需求和健康食品供应的策略来改善顾客的购买行为。
