目的.当地的食物环境可以通过食物供应、零售店的邻近程度、定价和促销来影响个人的饮食和健康。这项研究的重点是如何小型便利店，在纽约市称为酒窖，影响居民的购物行为和食品环境。使用横截面设计，171酒窖和2118购物者进行了抽样。纽约市的小型便利店。任何18岁以上的博德加购物者从参与商店购买食品或饮料。数据收集包括商店评估，对现有客户的健康和行为调查，以及记录所有客户购买的产品信息的袋子检查。对博德加商店特征、购物者人口统计学和购买行为进行了描述性统计。多层次模型被用来评估产品的可用性，位置和广告对消费者购买含糖饮料（SSB），水，水果和蔬菜的影响。71%的参与者报告每周在酒窖购物五次或更多次，35%的人报告在酒窖购买全部或大部分每月食物配额。模型结果表明，可用新鲜农产品的数量较少与SSB购买的可能性较高显着且独立相关。第二，分层多层次模型表明，购买SSB的可能性增加，减少品种的农产品时，生产位于前面的商店。水的放置和饮料的放置没有发现显著的影响。纽约市的小型便利店是食品和饮料的方便来源。酒窖可能适用于旨在改善食物选择和饮食的干预措施。
Purpose. Local food environments can influence the diet and health of individuals through food availability, proximity to retail stores, pricing, and promotion. This study focused on how small convenience stores, known in New York City as bodegas, influence resident shopping behavior and the food environment.Design. Using a cross-sectional design, 171 bodegas and 2118 shoppers were sampled.Setting. Small convenience stores in New York City.Subjects. Any bodega shopper aged 18+ who purchased food or beverage from a participating store.Measures. Data collection consisted of a store assessment, a health and behavior survey given to exiting customers, and a bag check that recorded product information for all customer purchases.Analysis. Descriptive statistics were generated for bodega store characteristics, shopper demographics, and purchase behavior. Multilevel models were used to assess the influence of product availability, placement, and advertising on consumer purchases of sugar-sweetened beverages (SSBs), water, and fruits and vegetables.Results. Seventy-one percent of participants reported shopping at bodegas five or more times per week, and 35% reported purchasing all or most of their monthly food allotment at bodegas. Model results indicated that lower amounts of available fresh produce were significantly and independently associated with a higher likelihood of SSB purchases. A second, stratified multilevel model showed that the likelihood of purchasing an SSB increased with decreasing varieties of produce when produce was located at the front of the store. No significant effects were found for water placement and beverage advertising.Conclusions. Small convenience stores in New York City are an easily accessible source of foods and beverages. Bodegas may be suitable for interventions designed to improve food choice and diet.
