This study evaluated a neighborhood environment survey and compared the physical activity and weight status of the residents in 2 neighborhoods.
On 2 occasions, 107 adults from neighborhoods with differing "walkability" were selected to complete a survey on their neighborhood environment. Physical activity was assessed by self-report and by accelerometer; height and weight were assessed by self-report.
Neighborhood environment characteristics had moderate to high test-retest reliabilities. Residents of high-walkability neighborhoods reported higher residential density, land use mix, street connectivity, aesthetics, and safety. They had more than 70 more minutes of physical activity and had lower obesity prevalence (adjusted for individual demographics) than did residents of low-walkability neighborhoods.
The reliability and validity of self-reported neighborhood environment subscales were supported. Neighborhood environment was associated with physical activity and overweight prevalence.
本研究评估了一项邻里环境调查,并比较了两个社区居民的身体活动和体重状况。
分两次从具有不同“可步行性”的社区中选取107名成年人,完成关于其邻里环境的调查。通过自我报告和加速度计评估身体活动;通过自我报告评估身高和体重。
邻里环境特征具有中等到较高的重测信度。高可步行性社区的居民报告居住密度更高、土地利用混合度更高、街道连通性更好、美观度更高且安全性更高。与低可步行性社区的居民相比,他们的身体活动时间多70多分钟,肥胖患病率更低(根据个体人口统计学因素进行了调整)。
自我报告的邻里环境分量表的信度和效度得到了支持。邻里环境与身体活动及超重患病率相关。
