目标：与不活跃的通勤者相比，步行或骑自行车上学的儿童进行更高水平的身体活动。然而，尽管增加身体活动的好处，积极通勤上学（ACS）和儿童体重指数之间的观察到的关联已经混合，可能是由于致肥胖的食物环境，一些儿童可能会暴露在沿着的路线从家到学校。我们的目的是检查周围的食物环境是否儿童的家园缓和ACS和儿童身体质量指数z-scores（zBMI）之间的关联方法：我们进行了多变量回归分析，利用横截面数据从家庭调查分布在2014年在新泽西的四个低收入城市（n = 627）。我们对孩子的家和食品店使用了地理编码地址（即，有限服务的[快餐]餐馆，便利店，小杂货店，超市），以表征0.25英里内的儿童的home.Results的食品环境：在积极的通勤者，大量的便利店和快餐店和至少有一个小杂货店在家附近的存在与较高的zBMI;在不经常上下班上学的儿童中没有这种联系。相应地，ACS与较低的zBMI之间的积极通勤者，但只有在不太不健康的食品environments.Conclusions：研究结果表明，不健康的食品环境有可能阻碍ACS和儿童体重之间的有益关联。支持ACS的政策和干预措施还应鼓励在儿童经常光顾的食品店提供和推广健康食品。
Objectives: Children who walk or bike to school engage in higher levels of physical activity compared to non-active commuters. However, despite the established benefits of increased physical activity, the observed association between active commuting to school (ACS) and child body mass index has been mixed, possibly due to obesogenic food environments to which some children may be exposed along the route between home and school. Our aim was to examine whether the food environment surrounding children's homes moderated the association between ACS and child body mass index z-scores (zBMI).Methods: We conducted multivariable regression analyses utilizing cross-sectional data from a household survey distributed in 2014 within four low-income cities in New Jersey (n = 627). We used geocoded addresses for the child's home and for food outlets (i.e., limited-service [fast food] restaurants, convenience stores, small grocery stores, and supermarkets) to characterize the food environment within 0.25 miles of the child's home.Results: Among active commuters, a larger number of convenience stores and fast-food restaurants and the presence of at least one small grocery store near home were associated with higher zBMI; there was no such association among children who were not active commuters to school. Correspondingly, ACS was associated with lower zBMI among active commuters, but only within less unhealthy food environments.Conclusions: Findings suggest that unhealthy food environments have the potential to impede the beneficial association between ACS and child weight. Policy and intervention efforts to support ACS should also encourage the availability and promotion of healthy foods in food outlets fre-quented by children.
