Personal air pollution monitoring in research studies should not interfere with usual patterns of behavior and bias results. In an urban pediatric cohort study we tested whether wearing an air monitor impacted activity time based on continuous watch-based accelerometry. The majority (71%) reported that activity while wearing the monitor mimicked normal activity. Correspondingly, variation in activity while wearing versus not wearing the monitor did not differ greatly from baseline variation in activity (P = 0.84).

评估儿童暴露于空气污染的程度：确定佩戴个人监护仪是否会影响体育锻炼。

研究中的个人空气污染监测不应干扰正常的行为方式和偏见。在一项城市儿童队列研究中，我们基于连续的基于手表的加速度计，测试了佩戴空气监测仪是否会影响活动时间。绝大多数（71％）报告说，在佩戴监护仪时的活动模仿了正常活动。相应地，佩戴和不佩戴监护仪时的活动变化与基线活动变化无显着差异（P = 0.84）。
