The American Diabetes Association (ADA) recommends healthful food choices; however, some geographic areas are limited in the types of foods they offer. Little is known about the role of convenience stores as viable channels to provide healthier foods in our "grab and go" society. The purposes of this study were to (1) identify foods offered within convenience stores located in two Bexar County, Texas, ZIP Codes and (2) compare the availability and cost of ADA-recommended foods including beverages, produce, grains, and oils/fats. Data were analyzed from 28 convenience store audits performed in two sociodemographically diverse ZIP Codes in Bexar County, Texas. Chi-squared tests were used to compare food availability, and t-tests were used to compare food cost in convenience stores between ZIP Codes. A significantly larger proportion of convenience stores in more affluent areas offered bananas (χ (2) = 4.17, P = 0.003), whole grain bread (χ (2) = 8.33, P = 0.004), and baked potato chips (χ (2) = 13.68, P < 0.001). On average, the price of diet cola (t = -2.12, P = 0.044) and certain produce items (e.g., bananas, oranges, tomatoes, broccoli, and cucumber) was significantly higher within convenience stores in more affluent areas. Convenience stores can play an important role to positively shape a community's food environment by stocking healthier foods at affordable prices.
美国糖尿病协会（ADA）建议选择健康的食物；然而，一些地区在食物种类方面受到限制。关于便利店作为在我们的“即拿即走”社会中提供更健康食品的可行渠道的作用，知之甚少。本研究的目的是：（1）确定位于德克萨斯州贝克萨尔县两个邮政编码内的便利店提供的食品；（2）比较便利店中 ADA 推荐食品的供应情况和价格，包括饮料、农产品、谷物和油/脂肪。从德克萨斯州贝克萨尔县两个社会人口统计学差异较大的邮政编码内进行的 28 次便利店审计中收集了数据。使用卡方检验比较食品供应情况，使用 t 检验比较两个邮政编码内便利店的食品成本。在较富裕地区的便利店中，香蕉（χ (2) = 4.17，P = 0.003）、全麦面包（χ (2) = 8.33，P = 0.004）和烤薯片（χ (2) = 13.68，P < 0.001）的供应比例明显更高。平均而言，在较富裕地区的便利店中，低糖可乐（t = -2.12，P = 0.044）和某些农产品（如香蕉、橙子、西红柿、西兰花和黄瓜）的价格明显更高。便利店可以通过以负担得起的价格储存更健康的食品，在塑造社区食品环境方面发挥重要作用。
