目的。纳瓦霍族保留地 (NN) 食品店中健康食品的供应量和负担能力较低可能是纳瓦霍人肥胖率高的社区一级风险因素。这项研究评估了整个 NN.Design 中超市和便利店食品和饮料的供应情况和定价。使用商店审核工具中的营养环境测量调查进行描述性研究设计。设置。 NN 上的超市 (n = 13) 和便利店 (n = 50) 以及边境城镇超市 (n = 9)。 受试者。不适用。措施。健康和不健康食品的供应和定价。分析。描述性分析和 chi(2) 分析。结果。与纳瓦霍超市相比，纳瓦霍便利店提供的健康食品选择较少。在纳瓦霍便利店，100% 全谷物产品、低脂奶酪、瘦肉、低脂薯片和脱脂或清淡热狗的数量少于相应的不太健康版本（均 p < 0.05）。在纳瓦霍超市和便利店，100% 全麦面包、瘦肉冷盘和低脂奶酪的单位价格都比相应的不太健康的版本更贵（均 p < 0.05）。结论。根据这项研究，纳瓦霍便利店不像纳瓦霍超市那样容易买到更健康的食品。改善各种规模的预订商店中更健康食品的获取和负担能力可能会支持纳瓦霍居民的健康饮食。
Purpose. Low availability and affordability of healthier foods in food stores on the Navajo Nation (NN) may be a community-level risk factor for the high prevalence of obesity among the Navajo people. This study assessed the availability and pricing of foods and beverages in supermarkets and convenience stores throughout the NN.Design. Descriptive study design using the Nutrition Environment Measurement Survey in Stores audit tool.Setting. Supermarkets (n = 13) and convenience stores (n = 50) on NN and border-town supermarkets (n = 9).Subjects. Not applicable.Measures. Availability and pricing of healthy and less-healthy foods.Analysis. Descriptive and chi(2) analyses.Results. Navajo convenience stores offered fewer healthier food options compared to Navajo supermarkets. In Navajo convenience stores, 100% whole grain products, reduced-fat cheese, lean meats, reduced-fat chips, and fat-free or light hot dogs were available in fewer stores than their corresponding less-healthy versions (all with p < .05). In both Navajo supermarkets and convenience stores, 100% whole wheat bread, lean cold cuts, and reduced-fat cheese were all more expensive per unit than their corresponding less-healthy versions (all with p < .05).Conclusions. According to this study, healthier foods are not as readily available in Navajo convenience stores as they are in Navajo supermarkets. Improving access to and affordability of healthier foods in reservation stores of all sizes may support healthy eating among Navajo residents.
