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).
在研究中进行个人空气污染监测不应干扰通常的行为模式并产生偏差结果。在一项城市儿科队列研究中,我们测试了佩戴空气监测器是否会根据连续基于观察的加速度计影响活动时间。大多数人(71%)报告说,佩戴监测器时的活动与正常活动相似。相应地,佩戴与不佩戴监测器时的活动变化与活动基线变化差异不大(P=0.84)。
