The aim of this study was to determine the relationship between the built environment and moderate-to-vigorous physical activity (MVPA) among adolescents aged 14−16 years. This study used a cross-lagged panel analysis to investigate the relationship between the urban built environment and adolescents’ MVPA in Shanghai, China. A total of 517 adolescents (275 boys and 242 girls) aged 14−17 years were recruited in Shanghai, China. Geographic information system technology was used to collect data on the built environment variables of the residential areas assessed. ActiGraphGT3X+ was used to monitor the physical activity of the adolescents at two time points (T1 and T2) spanning 2 years. The correlations between the T1 and T2 built environment variables were significant (r = 0.54−0.65, p < 0.05), and the T2 built environment was significantly better than the T1 built environment. The correlation between the T1 and T2 MVPA was significant (r = 0.28−0.56, p < 0.05), and the T2 weekend MVPA was higher than the T1 weekend MVPA. The T1 built environment could not predict the T2 weekday MVPA (β = 0.17, p > 0.05), but it positively predicted the T2 weekend MVPA (β = 0.24, p < 0.05). In conclusion, the urban built environment significantly affected weekend MVPA among adolescents.
本研究旨在确定 14-16 岁青少年的建成环境与中高强度身体活动（MVPA）之间的关系。本研究采用交叉滞后面板分析，调查了中国上海城市建成环境与青少年 MVPA 之间的关系。在中国上海，共招募了 517 名 14-17 岁的青少年（275 名男孩和 242 名女孩）。使用地理信息系统技术收集评估的居住区域建成环境变量数据。使用 ActiGraphGT3X+ 在 2 年的 2 个时间点（T1 和 T2）监测青少年的身体活动。T1 和 T2 建成环境变量之间的相关性显著（r = 0.54-0.65，p < 0.05），T2 建成环境明显优于 T1 建成环境。T1 和 T2 MVPA 之间的相关性显著（r = 0.28-0.56，p < 0.05），T2 周末 MVPA 高于 T1 周末 MVPA。T1 建成环境不能预测 T2 工作日 MVPA（β = 0.17，p > 0.05），但它能正向预测 T2 周末 MVPA（β = 0.24，p < 0.05）。综上所述，城市建成环境显著影响青少年周末的 MVPA。
