在美国，人们对食品商店环境变化与儿童肥胖风险之间的关系知之甚少。本研究探讨了儿童的体重状况与其社区食品商店数量的变化。一个具有全国代表性的美国学龄儿童队列从2004年的5年级到2007年的8年级（n=7090）。2004年和2007年，在学校直接测量儿童的身体质量指数。2004年和2007年人口普查局的邮政编码商业模式数据按商店类型对每个邮政编码地区的食品商店数量进行了描述：超市、有限服务餐馆、小型杂货店和便利店。基准及店铺数目变动为主要关注风险。三年后，生活在有≥ 3家超市的社区的女孩的BMI较低（-0.62 kg/m2; 95% C.I.：-1.05，-0.18），而那些生活在没有超市的社区的人。三年后，生活在有许多有限服务餐馆的社区的女孩的BMI更高（1.02 kg/m2; 95% CI：0.36，1.68）比那些生活在≤1个有限服务餐厅的社区。接触社区中数量减少的小型杂货店与八年级女孩的较低BMI相关。邻里食物环境和儿童BMI之间的纵向关联因性别而异。对于女孩来说，社区的超市似乎可以防止肥胖，而社区的小型杂货店和服务有限的餐馆增加了肥胖的风险。男孩没有显著的纵向发现。
Little is known about the relationship between changes in food store environment and children’s obesity risk in the US. This study examines children’s weight status associated with the changes in the quantity of food stores in their neighborhoods. A nationally representative cohort of schoolchildren in the US was followed from 5th grade in 2004 to 8th grade in 2007 (n=7090). In 2004 and 2007, children’s body mass index (BMI) was directly measured in schools. ZIP-Code Business Patterns data from the Census Bureau in 2004 and 2007 characterized the numbers of food stores in every ZIP-code area by type of store: supermarkets, limited-service restaurants, small-size grocery and convenience stores. Baseline and change in the numbers of stores were the major exposures of interest. Girls living in neighborhoods with ≥ 3 supermarkets had a lower BMI three years later (by −0.62 kg/m2; 95% C.I.: −1.05, −0.18) than did those living in neighborhoods without any supermarkets. Girls living in neighborhoods with many limited-service restaurants had a greater BMI three years later (by 1.02 kg/m2; 95% C.I.: 0.36, 1.68) than did those living in neighborhoods with ≤1 limited-service restaurant. Exposure to a decreased quantity of small-size grocery stores in neighborhoods was associated with girls’ lower BMI by eighth grade. The longitudinal association between neighborhood food environment and children’s BMI differed by gender. For girls, supermarkets in neighborhoods seemed protective against obesity, while small-size grocery stores and limited-service restaurants in neighborhoods increased obesity risk. There was no significant longitudinal finding for boys.
