青少年肥胖是一个全国性的公共卫生问题，特别是在城市人口中。最近的证据表明，附近的食物环境与健康和营养状况有关，更容易进入便利店与肥胖风险增加有关。人们对城市小型食品店是否有健康的购买选择以及这些因素与年轻人的相关程度知之甚少。本研究的目的是描述城市初中和高中附近小型便利店内食品环境的各种特征。对位于明尼苏达州 36 所城市公立中学 800 m 范围内的 63 家商店进行了店内审计。结果表明，大多数商店都提供数量有限的健康饮料（即水和 100% 果汁）和零食（即坚果和椒盐卷饼）（千分之一日元85%）。然而，通常没有多种健康零食可供选择，不到一半的商店备有许多特定商品（例如，27% 的商店有低脂酸奶，43% 的商店有低脂格兰诺拉麦片棒）。总体而言，51% 的商店有新鲜水果，49% 的商店有新鲜蔬菜。很少有商店提供一系列更健康的单份包装零食替代品。所有商店的健康冲动购买商品（例如糖果）均较少，而只有 46% 的商店出售更健康的冲动购买商品（例如水果）。大多数商店（97%）都有食品/饮料广告。总体而言，靠近中学的便利店是青年食品环境中一个重要且未被充分研究的组成部分。
Adolescent obesity is a national public health problem, particularly among urban populations. Recent evidence has linked neighborhood food environments to health and nutrition status, with easier access to convenience stores being associated with increased risk for obesity. Little is known about the availability of healthy purchasing options within small, urban food stores, or the extent to which these factors are relevant to youth. The objective of this research was to characterize various features of the food environment within small convenience stores located nearby urban junior high and high schools. In-store audits were conducted in 63 stores located within 800 m of 36 urban Minnesota public secondary schools. Results indicated that a limited number of healthier beverages (i.e., water and 100% fruit juice) and snack options (i.e., nuts and pretzels) were available at most stores (a parts per thousand yen85%). However, a wide range of healthy snack options were typically not available, with many specific items stocked in less than half of stores (e.g., low-fat yogurt in 27% of stores and low-fat granola bars in 43%). Overall, 51% of stores had fresh fruit and 49% had fresh vegetables. Few stores carried a range of healthier snack alternatives in single-serving packages. All stores had less healthful impulse purchase items available (e.g., candy) while only 46% carried healthier impulse items (e.g., fruit). Most stores (97%) had food/beverage advertising. Overall, convenience stores located in close proximity to secondary schools represent an important and understudied component of the youth food environment.
