OBJECTIVE
To characterize the overall availability, price, and promotional placement of food and beverage products at dollar stores and explore differences in the food environment by neighborhood racial composition in Atlanta, Georgia.
METHODS
A cross-sectional assessment of the food environment was conducted at 25 dollar stores. Measures included availability, affordability, and promotion of fresh produce, salty snacks, sweet snacks, sugar-sweetened beverages (SSBs), and water. Store neighborhoods were categorized as majority-Black (MB) or non-majority-Black (NMB) neighborhoods using American Community Survey data. Kruskal Wallis and chi-square tests (test of independence) were used to test for differences across neighborhood racial composition.
RESULTS
Only 2 stores sold fresh produce, whereas all offered and most promoted sweet snacks, salty snacks, and SSBs. Compared with NMB neighborhoods, prices for SSBs and salty snacks were significantly lower in MB neighborhoods (P < 0.05).
CONCLUSIONS AND IMPLICATIONS
The dollar store food environment lacks fresh produce and comprises largely unhealthy food options. Findings suggest dollar stores in MB neighborhoods may provide lower prices for unhealthy food and beverages.
目的
描述一元店食品和饮料产品的总体可获得性、价格及促销情况，并探讨佐治亚州亚特兰大市不同种族构成社区的食品环境差异。
方法
对25家一元店的食品环境进行横断面评估。评估指标包括新鲜农产品、咸味零食、甜味零食、含糖饮料（SSB）和水的可获得性、可负担性及促销情况。利用美国社区调查数据将商店所在社区分为黑人占多数（MB）或非黑人占多数（NMB）社区。采用Kruskal Wallis检验和卡方检验（独立性检验）来检验不同种族构成社区之间的差异。
结果
只有2家商店销售新鲜农产品，而所有商店都提供且大多数商店促销甜味零食、咸味零食和含糖饮料。与非黑人占多数社区相比，黑人占多数社区的含糖饮料和咸味零食价格显著更低（P < 0.05）。
结论与启示
一元店的食品环境缺乏新鲜农产品，主要由不健康的食品选择构成。研究结果表明，黑人占多数社区的一元店可能提供价格更低的不健康食品和饮料。
