Many small grocery stores or "bodegas" sell prepared or ready-to-eat items, filling a niche in the food environment similar to fast-food restaurants. However, little comparative information is available about the nutrition environments of bodegas and fast-food outlets. This study compared the nutrition environments of bodegas and national chain fast-food restaurants using a common audit instrument, the Nutrition Environment Measures Study in Restaurants (NEMS-R) protocol. The analytic sample included 109 bodegas and 107 fast-food restaurants located in New York City neighborhoods in the upper third and lower third of the census tract poverty rate distribution. Inter-rater reliability was evaluated in 102 food outlets, including 31 from the analytic sample and 71 from a supplementary convenience sample. The analysis compared scores on individual NEMS-R items, a total summary score, and subscores indicating healthy food availability, nutrition information, promotions of healthy or unhealthy eating, and price incentives for healthy eating, using t tests and χ(2) statistics to evaluate differences by outlet type and neighborhood poverty. Fast-food restaurants were more likely to provide nutrition information, and bodegas scored higher on healthy food availability, promotions, and pricing. Bodegas and fast-food restaurants had similar NEMS-R total scores (bodegas 13.09, fast food 14.31; P=0.22). NEMS-R total scores were higher (indicating healthier environments) in low- than high-poverty neighborhoods among both bodegas (14.79 vs 11.54; P=0.01) and fast-food restaurants (16.27 vs 11.60; P<0.01). Results imply different policy measures to improve nutrition environments in the two types of food outlets.
许多小型杂货店或“bodegas”出售预制或即食食品,填补了快餐的食品环境的空白。然而,关于 bodegas 和快餐的营养环境的比较信息却很少。本研究使用通用审核工具——餐厅营养环境测量研究(NEMS-R)协议,比较了 bodegas 和全国连锁快餐店的营养环境。分析样本包括位于纽约市社区的 109 家 bodegas 和 107 家快餐店,这些社区位于人口普查区贫困率分布的上三分之一和下三分之一。在 102 家食品店中评估了内部评估者的可靠性,其中包括 31 家来自分析样本和 71 家补充便利样本。该分析比较了单个 NEMS-R 项目的分数、总分以及表明健康食品供应、营养信息、健康或不健康饮食的促销和健康饮食的价格激励的子分数,使用 t 检验和 χ(2)统计数据根据门店类型和社区贫困状况评估差异。快餐店更有可能提供营养信息,而 bodegas 在健康食品供应、促销和定价方面得分更高。bodegas 和快餐店的 NEMS-R 总分相似(bodegas 为 13.09,快餐店为 14.31;P=0.22)。在 bodegas(14.79 比 11.54;P=0.01)和快餐店(16.27 比 11.60;P<0.01)中,低贫困社区的 NEMS-R 总分(表明更健康的环境)均高于高贫困社区。结果表明,对于这两种类型的食品店,需要采取不同的政策措施来改善营养环境。
