The objective of the Pathways physical activity feasibility study was to develop methods for comparing type and amount of activity between intervention and control schools participating in a school-based obesity prevention program. Two methods proved feasible: 1) a specially designed 24-h physical activity recall questionnaire for assessing the frequency and type of activities and 2) use of a triaxial accelerometer for assessing amount of activity. Results from pilot studies supporting the use of these methods are described. Analyses of activity during different segments of the day showed that children were most active after school. The activities reported most frequently (e.g., basketball and mixed walking and running) were also the ones found to be most popular in the study population on the basis of formative assessment surveys. Both the physical activity recall questionnaire and the triaxial accelerometer methods will be used to assess the effects of the full-scale intervention on physical activity.
“路径”体育活动可行性研究的目的是开发方法，以比较参与一项基于学校的肥胖预防计划的干预学校和对照学校之间的活动类型和活动量。两种方法被证明是可行的：1）一份专门设计的24小时体育活动回忆问卷，用于评估活动的频率和类型；2）使用三轴加速度计评估活动量。文中描述了支持使用这些方法的初步研究结果。对一天中不同时段活动的分析表明，孩子们放学后最活跃。根据形成性评估调查，报告频率最高的活动（如篮球以及混合的步行和跑步）也是在研究人群中最受欢迎的活动。体育活动回忆问卷和三轴加速度计这两种方法都将用于评估全面干预对体育活动的影响。
