目的.研究社区步行能力和娱乐环境变量与体力活动的关系。这项横断面研究对98名白色或墨西哥裔美国青少年（平均年龄= 16.2岁）进行。通过7天的加速度计监测来测量身体活动。测量身高和体重，计算体重指数（BMI）。利用地理信息系统制定了环境措施。邻里步行指数是基于土地使用组合，零售密度，街道连通性和住宅密度。接近公共和私人娱乐设施进行了评估。在线性回归中，距离住宅0.5英里内的步行指数与中等至剧烈体力活动的分钟数有关，解释了约4%的方差。娱乐变量与体力活动无关，BMI不能用环境变量来解释。结论。社区步行能力与青少年的身体活动有关，与成人的研究结果相似。
Purpose. To examine associations of neighborhood walkability and recreation environment variables with physical activity in adolescents.Methods. The cross-sectional study was conducted with 98 white or Mexican-American adolescents (mean age = 16.2 years). Physical activity was measured with 7 days of accelerometer monitoring. Height and weight were measured to compute body mass index (BMI). Environmental measures were created using geographic information systems. A neighborhood walkability index was based on land use mix, retail density, street connectivity, and residential density. Proximity to public and private recreation facilities was assessed.Results. In a linear regression, the walkability index within 0.5 mile of homes was related to minutes of moderate to vigorous physical activity, explaining approximately 4% of variance. Recreation variables were not related to physical activity, and BMI was not explained by environmental variables.Conclusion. Neighborhood walkability was related to adolescents' physical activity, similar to findings for adults.
