The built environment may influence weight status.
Using cross-sectional data for children aged 2 to 18 years, the authors linked clinical and spatial data using geographic information systems and analyzed for associations between body mass index (BMI) and density of and distance to nearest built environment variable (schools, sidewalks, subway stations, bicycle trails, open space, and fast-food restaurants) using bivariate and multilevel analyses.
The study sampled 21 008 children; 54% were white, 26% Hispanic, 37% overweight, and 20% obese. In bivariate analysis, distance to nearest fast-food restaurant was inversely associated with BMI, whereas density of fast-food restaurants was positively associated with BMI. Distance to school and subway station, amount of open space, and density of subway stations were inversely associated with BMI. Controlling for sociodemographic factors, only living near a greater density of subway stations was inversely associated with overweight (odds ratio, 0.87; 95% confidence interval, 0.81-0.94) and obesity (odds ratio, 0.90; 95% confidence interval, 0.82-0.99).

建筑环境可能会影响体重状况。
作者利用2至18岁儿童的横断面数据，通过地理信息系统将临床数据与空间数据相联系，并使用双变量分析和多水平分析，分析体重指数（BMI）与最近建筑环境变量（学校、人行道、地铁站、自行车道、开放空间和快餐店）的密度及距离之间的关联。
该研究对21008名儿童进行了抽样；54%为白人，26%为西班牙裔，37%超重，20%肥胖。在双变量分析中，与最近快餐店的距离与BMI呈负相关，而快餐店的密度与BMI呈正相关。与学校和地铁站的距离、开放空间的数量以及地铁站的密度与BMI呈负相关。在控制了社会人口统计学因素后，仅居住在地铁站密度较高的附近地区与超重（比值比，0.87；95%置信区间，0.81 - 0.94）和肥胖（比值比，0.90；95%置信区间，0.82 - 0.99）呈负相关。
