美洲印第安儿童的高肥胖率导致了 Pathways 的开展，这是一项随机学校和社区儿童预防研究。七个部落、五所大学、NIH/NHLBI 和四所小学进行了合作。增加体力活动（PA）是一个重要的干预目标。 PA 评估基于研究目标、可行性和部落接受度。还需要进行时间分段分析。在试点测试期间开发了两种方法：新的 PA 问卷和加速度测量法。这些方法共同提供了定性和定量信息，并显示 4 个站点中的 3 个能够提高平均每日 PA，尽管总体而言，控制与干预的差异并不显着。主要限制是无法区分个体之间的 PA。加速度计的尺寸和一些社区关注导致了基于单日佩戴时间的协议。建议在未来的研究中使用更新型号的三轴加速度计，其尺寸要小得多，并且可以对多天的活动进行采样。
High obesity rates in American Indian children led to Pathways, a randomized school and community-based childhood prevention study. Seven tribes, five universities, the NIH/NHLBI, and four elementary schools partnered. Increasing physical activity (PA) was an important intervention target. PA assessment was based on study objectives, feasibility, and tribal acceptance. A time-segmented analysis was also desired. Two methods were developed during pilot testing, a new PA questionnaire and accelerometry. Together, the methods provided qualitative and quantitative information and showed 3 of 4 sites were able to increase average daily PA, although overall the control versus intervention difference was not significant. The main limitation was inability to distinguish PA among individuals. Accelerometer size and some community concerns led to a protocol based on a single day of wearing time. Newer model triaxial accelerometers which are much smaller and allow sampling of multiple days of activity are recommended for future studies.
