More information about children's physical activity during different periods of the day is needed. The purpose of this study was to describe children's physical activity during the segmented school day and examine potential differences during different periods of the day across gender, travel mode to school and weight status.
School children (N=247) wore pedometers for four consecutive school days and recorded their steps during the before school period, the 20-min school break, the whole school period, the after school period and for the whole day. Children also reported how they traveled to school. Data were collected in Cyprus, in January/February of 2007.
T-tests indicated that boys took significantly higher steps than girls throughout all the segments of the day (p<0.001) and children who walked to school exhibited higher step counts during the before school period (p<0.001), the after school period (p<0.01), and the whole day (p<0.01) in comparison to children who used motorized transport. A three-way ANOVA revealed significant two-way interactions between weight status and travel mode to school.
Results suggest that there is a need to promote physical activity among children, especially among girls. Promoting active transport to school may further enhance the effectiveness of intervention programs.
需要更多关于儿童在一天中不同时段身体活动情况的信息。本研究的目的是描述儿童在分段上学日期间的身体活动情况,并研究在一天中的不同时段,不同性别、上学出行方式和体重状况之间的潜在差异。
学童(N = 247)连续四个上学日佩戴计步器,并记录他们在上学前时段、20分钟课间休息、整个上学时段、放学后时段以及一整天的步数。孩子们还报告了他们上学的出行方式。数据于2007年1月/2月在塞浦路斯收集。
t检验表明,在一天中的所有时段,男孩的步数都显著高于女孩(p < 0.001),与使用机动交通工具上学的孩子相比,步行上学的孩子在上学前时段(p < 0.001)、放学后时段(p < 0.01)和一整天(p < 0.01)的步数更多。三因素方差分析显示体重状况和上学出行方式之间存在显著的双向交互作用。
结果表明有必要促进儿童的身体活动,尤其是女孩。推广积极的上学交通方式可能会进一步提高干预项目的效果。
