We investigated the association between physical and social neighborhood environments and fifth-grade students' physical activity and obesity.
We collected data on 650 children and their primary caregivers during phase 1 of Healthy Passages, a multisite, community-based, cross-sectional study of health risk behaviors and health outcomes in children. We conducted independent systematic neighborhood observations to measure neighborhood physical characteristics, and we analyzed survey data on social processes. We modeled children's physical activity and obesity status with structural equation models that included latent variables for the physical and social environments.
After we controlled for children's sociodemographic factors, we found that a favorable social environment was positively associated with several measures of physical activity and that physical activity was negatively associated with obesity in these children. Physical environment was not significantly associated with physical activity.
Our findings suggest that neighborhood social factors as well as the physical environment should be considered in the development of health policy and interventions to reduce childhood obesity.
我们研究了邻里的物理环境和社会环境与五年级学生身体活动及肥胖之间的关联。
在“健康通道”研究的第一阶段，我们收集了650名儿童及其主要照顾者的数据，该研究是一项多地点、基于社区的关于儿童健康风险行为和健康结果的横断面研究。我们进行了独立的系统性邻里观察以测量邻里的物理特征，并分析了关于社会过程的调查数据。我们使用结构方程模型对儿童的身体活动和肥胖状况进行建模，该模型包含物理和社会环境的潜在变量。
在控制了儿童的社会人口学因素后，我们发现良好的社会环境与多种身体活动指标呈正相关，并且身体活动与这些儿童的肥胖呈负相关。物理环境与身体活动没有显著关联。
我们的研究结果表明，在制定减少儿童肥胖的健康政策和干预措施时，应考虑邻里社会因素以及物理环境。
