School travel mode and parenting practices have been associated with children's physical activity (PA). The current study sought to examine whether PA parenting practices differ by school travel mode and whether school travel mode and PA parenting practices are associated with PA.
469 children (aged 9-11) wore accelerometers from which mean weekday and after-school (3.30 to 8.30 pm) minutes of moderate-to-vigorous intensity PA (MVPA) and counts per minute (CPM) were derived. Mode of travel to and from school (passive vs. active) and PA parenting practices (maternal and paternal logistic support and modelling behaviour) were child-reported.
Children engaged in an average of 59.7 minutes of MVPA per weekday. Active travel to school by girls was associated with 5.9 more minutes of MVPA per day compared with those who travelled to school passively (p = 0.004). After-school CPM and MVPA did not differ by school travel mode. There was no evidence that physical activity parenting practices were associated with school travel mode.
For girls, encouraging active travel to school is likely to be important for overall PA. Further formative research may be warranted to understand how both parental logistic support and active travel decisions are operationalized in families as a means of understanding how to promote increased PA among pre-adolescent children.
上学出行方式和育儿方式与儿童的身体活动（PA）有关。本研究旨在探讨身体活动育儿方式是否因上学出行方式而异，以及上学出行方式和身体活动育儿方式是否与身体活动相关。
469名9至11岁的儿童佩戴了加速度计，从中得出工作日和放学后（下午3:30至8:30）中度至剧烈强度身体活动（MVPA）的平均分钟数以及每分钟计数（CPM）。往返学校的出行方式（被动出行与主动出行）和身体活动育儿方式（母亲和父亲的后勤支持及示范行为）由儿童报告。
儿童平均每个工作日进行59.7分钟的中度至剧烈强度身体活动。与被动上学的女孩相比，主动上学的女孩每天进行中度至剧烈强度身体活动的时间多5.9分钟（p = 0.004）。放学后的每分钟计数和中度至剧烈强度身体活动在上学出行方式上没有差异。没有证据表明身体活动育儿方式与上学出行方式有关。
对于女孩来说，鼓励主动上学对总体身体活动可能很重要。可能需要进一步开展形成性研究，以了解父母的后勤支持和主动出行决策在家庭中是如何实施的，以此作为理解如何促进青春期前儿童增加身体活动的一种方式。
