This study used latent class analysis to classify adolescent home neighborhoods (n=344) according to built environment characteristics, and tested how adolescent physical activity, sedentary behavior, and screen time differ by neighborhood type/class. Four distinct neighborhood classes emerged: (1) low-density retail/transit, low walkability index (WI), further from recreation; (2) high-density retail/transit, high WI, closer to recreation; (3) moderate-high-density retail/transit, moderate WI, further from recreation; and (4) moderate-low-density retail/transit, low WI, closer to recreation. We found no difference in adolescent activity by neighborhood class. These results highlight the difficulty of disentangling the potential effects of the built environment on adolescent physical activity.
本研究采用潜在类别分析,根据建成环境特征对青少年的居住社区(n=344)进行分类,并检验不同邻里类型/类别下青少年的身体活动、久坐行为和屏幕时间的差异。研究结果显示,四个不同的邻里类型分别为:(1)低密度零售/交通,低步行指数(WI),离娱乐设施更远;(2)高密度零售/交通,高 WI,离娱乐设施更近;(3)中高密度零售/交通,中等 WI,离娱乐设施更远;和(4)中低密度零售/交通,低 WI,离娱乐设施更近。我们发现邻里类型与青少年的活动水平没有差异。这些结果突出了环境对青少年身体活动的潜在影响的复杂性。
