This study investigated whether being driven to school was associated with lower weekday and weekend step counts, less active out-of-school leisure pursuits, and more sedentary behavior. Boys aged 10-13 years (n = 384) and girls aged 9-13 years (n = 500) attending 25 Australian primary schools wore a pedometer and completed a travel diary for one week. Parents and children completed surveys capturing leisure activity, screen time, and sociodemographics. Commute distance was objectively measured. Car travel was the most frequent mode of school transportation (boys: 51%, girls: 58%). After adjustment (sociodemographics, commute distance, and school clustering) children who were driven recorded fewer weekday steps than those who walked (girls: -1,393 steps p < .001, boys: -1,569 steps, p = .009) and participated in fewer active leisure activities (girls only: p = .043). There were no differences in weekend steps or screen time. Being driven to and from school is associated with less weekday pedometer-determined physical activity in 9- to 13-year-old elementary-school children. Encouraging children, especially girls, to walk to and from school (even for part of the way for those living further distances) could protect the health and well-being of those children who are insufficiently active.
本研究调查了乘车上学是否与工作日和周末步数减少、校外休闲活动活跃度降低以及久坐行为增多有关。来自澳大利亚25所小学的10至13岁男孩（n = 384）和9至13岁女孩（n = 500）佩戴了计步器，并记录了一周的出行日记。家长和孩子完成了关于休闲活动、屏幕使用时间和社会人口统计学的调查。通勤距离通过客观测量得出。乘车是最常见的上学交通方式（男孩：51%，女孩：58%）。在进行调整（社会人口统计学、通勤距离和学校聚类）后，乘车上学的孩子在工作日的步数比步行上学的孩子少（女孩：少1393步，p < .001；男孩：少1569步，p = .009），并且参与的积极休闲活动也较少（仅女孩：p = .043）。周末步数或屏幕使用时间没有差异。对于9至13岁的小学生来说，乘车上下学与工作日计步器测定的身体活动较少有关。鼓励孩子，尤其是女孩，步行上下学（即使住得较远的孩子只走一部分路程）可以保护那些活动不足的孩子的健康和幸福。
