背景：上学途中是增加儿童日常身体活动的一个契机。然而，积极通勤上学对总体身体活动的贡献尚不明确。本研究采用客观测量方法，按上学交通方式调查儿童的身体活动模式。
方法：小学生佩戴一个加速度计，该加速度计被设定为连续7天每分钟记录一次身体活动情况，并完成一份简要问卷，描述他们通常的上学交通方式。根据加速度计记录，估算出工作日和周末的身体活动总量以及至少中等强度活动所花费的时间，并按上学交通方式对儿童群体进行比较。数据收集于2002年5月/6月。
结果：在参与研究的114名儿童（59名男孩，55名女孩；年龄10.4±0.8岁）中，步行上学的儿童（65%）比乘车上学的儿童明显更活跃（每分钟加速度计计数分别为712.0±206.7和629.9±207.2，p = 0.05）。按性别分析表明，不同交通方式群体之间身体活动的主要差异仅在男孩中可见。每小时活动模式显示，步行上学的男孩在放学后和整个晚上都比乘车上学的男孩更活跃。
结论：在男孩中，步行上学与放学后和晚上更高的身体活动相关。积极的交通方式可能有助于形成更积极的身体活动状况，至少对男孩来说是这样，这支持了步行上学倡议以增加儿童的身体活动。
Background: The journey to school is an opportunity for increasing children's daily physical activity. However, the contribution that active commuting to school makes to overall physical activity is unknown. This study used objective measurement to investigate the physical activity patterns of children by mode of travel to school.Methods: Primary-school children wore an accelerometer programmed to record minute-by-minute physical activity for 7 days and completed a brief questionnaire describing their usual travel to school. The total volume of physical activity and the time spent in activity of at least moderate intensity, as recorded by the accelerometer, was estimated for weekdays and the weekend, and groups of children were compared by mode of transport to school. Data were collected in May/June 2002.Results: Of the 114 children (59 boys, 55 girls; aged 10.4 +/- 0.8 years) who took part in the study, those who walked to school (65%) were significantly more active than those who traveled by car (712.0 +/- 206.7 vs 629.9 +/- 207.2 accelerometer counts per minute, p = 0.05). Analysis by gender indicated that the major differences in physical activity between travel groups were seen only in boys. Hourly activity patterns demonstrated that boys who walked to school were more active after school and throughout the evening than were car users.Conclusions: In boys, walking to school was associated with higher physical activity after school and during the evening. Active transport may contribute to a more physically active profile, at least for boys, supporting walk-to-school initiatives to increase children's physical activity.
