Active school transport (AST) may be an important source of children's physical activity (PA). Innovative solutions that increase PA time for children, without putting added pressure on the school curriculum, merit consideration. Before implementing such solutions, it is important to demonstrate that active school transport is associated with health-related outcomes.
Following a standardized protocol, we conducted a systematic review of published research to address this question and explore whether children who actively commute to school also have a healthier body weight. Online searches of 5 electronic databases were conducted. Potential studies were screened on the basis of objective measures of physical activity.
Thirteen studies were included in this review. Nine studies demonstrated that children who actively commute to school accumulate significantly more PA and two studies reported that they expended significantly more kilocalories per day. Where studies examined body weight (n=10), only one reported active commuters having a lower body weight.
These studies demonstrate that active school commuters tend to be more physically active overall than passive commuters. However, evidence for the impact of AST in promoting healthy body weights for children and youth is not compelling.
积极的学校交通出行（AST）可能是儿童身体活动（PA）的一个重要来源。在不给学校课程增加额外压力的情况下，增加儿童身体活动时间的创新解决方案值得考虑。在实施此类解决方案之前，证明积极的学校交通出行与健康相关结果相关很重要。
按照标准化方案，我们对已发表的研究进行了系统综述，以解决这个问题，并探讨积极步行或骑车上学的儿童体重是否也更健康。对5个电子数据库进行了在线搜索。根据身体活动的客观测量指标筛选潜在研究。
本综述纳入了13项研究。9项研究表明，积极步行或骑车上学的儿童积累的身体活动显著更多，两项研究报告称他们每天消耗的卡路里显著更多。在研究体重的研究中（n = 本综述纳入了13项研究。9项研究表明，积极步行或骑车上学的儿童积累的身体活动显著更多，两项研究报告称他们每天消耗的卡路里显著更多。在研究体重的研究中（n = 10），只有一项报告称积极步行或骑车上学的儿童体重较低。
这些研究表明，与被动出行的儿童相比，积极步行或骑车上学的儿童总体上往往身体活动更多。然而，积极的学校交通出行对促进儿童和青少年健康体重的影响证据并不充分。
