背景资料：环境因素，如当地食品商店的可用性可能是美国青少年肥胖率上升的重要因素。方法：重复的横截面-从“监测未来”调查中获得的青少年水平数据通过地理编码标识符与食品店可用性数据相联系，用于研究青少年体重与四种食品杂货店可用性之间的关系包括连锁超市，非连锁超市，便利店，和其他杂货店，持有恒定的各种其他个人和邻里水平的influences.Results：增加可用性的连锁超市与较低的青少年身体质量指数（BMI）和超重，更大的便利店的可用性与较高的BMI和超重统计学显着相关。超市的可用性和重量之间的关联是更大的非洲裔美国学生相比，白色或西班牙裔学生和更大的学生在家庭中，母亲工作的全职.Conclusions：经济和城市规划的土地使用政策，增加了连锁超市的可用性可能对青少年的体重结果产生有益的影响。
Background: Environmental factors such as the availability of local-area food stores may be important contributors to the increasing rate of obesity among U.S. adolescents.Methods: Repeated cross-sections of individual-level data on adolescents drawn from the Monitoring the Future surveys linked by geocode identifiers to data on food store availability were used to examine associations between adolescent weight and the availability of four types of grocery food stores that include chain supermarkets, nonchain supermarkets, convenience stores, and other grocery stores, holding constant a variety of other individual- and neighborhood-level influences.Results: Increased availability of chain supermarkets was statistically significantly associated with lower adolescent Body Mass Index (BMI) and overweight and that greater availability of convenience stores was statistically significantly associated with higher BMI and overweight. The association between supermarket availability and weight was larger for African-American students compared to white or Hispanic students and larger for students in households in which the mother worked full time.Conclusions: Economic and urban planning land use policies which increase the availability of chain supermarkets may have beneficial effects on youths' weight outcomes.
