目的：本研究的目的是突出的相似性和差异之间的感知和客观措施的食品店环境低收入妇女和饮食和weight.Design的关联：食品店环境的横截面分析。商店水平的特点是：（一）参与者购物的商店中的健康食品的可用性，使用食品商店审计（目标）;和（二）自我报告的商店中健康食品的可用性（感知）的总结分数。邻里一级的特点是：（一）数量和类型的食品店内的普查范围（目标）;（2）自我报告的健康食品可获得性感知的汇总评分背景：北卡罗来纳州的六个县。受试者：186名低收入妇女。结果：居住在人口普查区的便利店和超级购物中心的人更有可能认为他们的社区健康食品供应量很高（OR = 6.87（95%CI 2.61，18.01））。总体而言，随着商店中健康食品数量的减少，感知商店中健康食品供应量高的可能性增加。在人口普查区域有超级中心的个体比没有超级中心的个体体重更重（2.40（95% CI 0.66，4.15）kg/m2）。与此同时，那些生活在人口普查区的超级购物中心和便利店消费较少的水果和蔬菜（-1.22（95%CI-2.40，-0.04））。结论：这项研究有助于越来越多的研究，旨在了解食品商店环境与体重和饮食的关系。
Objective: The present study aimed to highlight the similarities and differences between perceived and objective measures of the food store environment among low-income women and the association with diet and weight.Design: Cross-sectional analysis of food store environment. Store level was characterized by: (i) the availability of healthy foods in stores where participants shop, using food store audits (objective); and (ii) summary scores of self-reported perception of availability of healthy foods in stores (perceived). Neighbourhood level was characterized by: (i) the number and type of food stores within the census tract (objective); and (2) summary scores of self-reported perception of availability of healthy foods (perceived).Setting: Six counties in North Carolina.Subjects: One hundred and eighty-six low-income women.Results: Individuals who lived in census tracts with a convenience store and a supercentre had higher odds of perceiving their neighbourhood high in availability of healthy foods (OR = 6.87 (95% CI 2.61, 18.01)) than individuals with no store. Overall, as the number of healthy foods available in the store decreased, the probability of perceiving that store high in availability of healthy foods increased. Individuals with a supercentre in their census tract weighed more (2.40 (95% CI 0.66, 4.15) kg/m(2)) than individuals without one. At the same time, those who lived in a census tract with a supercentre and a convenience store consumed fewer servings of fruits and vegetables (-1.22 (95% CI -2.40, -0.04)).Conclusions: The study contributes to a growing body of research aiming to understand how the food store environment is associated with weight and diet.
