ActiGraph(GT3X/±系列)加速度计睡眠筛查方法研究进展

Research Progress on Sleep Screening Methods Using Actigraph(GT3X/±Series) Accelerometer

基于加速度计的24 h活动行为研究中,计算不同活动行为时间之前,必须先将加速度计数据分为清醒时期(研究身体活动和久坐行为)和睡眠时期(研究睡眠时间和睡眠质量)。但目前关于加速度计数据对清醒-睡眠期的分离尚无公认的标准方法,也缺乏对这些方法的系统梳理。研究从425篇相关文献中归纳出9种在自由生活条件下可用的清醒-睡眠期分离方法,通过解释这些方法的原理、优势与不足,为使用GT3X/±加速度计的研究人员提供选择睡眠筛查方法的建议:1)选择自动睡眠筛查算法时,腕部设备推荐使用GGIR内置的睡眠日记/HDCZA算法+van Hees 2015算法,腰部设备则可以选择Tracy ProChildren、Tudor-Locke、McVeigh或Bellettiere-McVeigh算法;2)选择Actilife进行睡眠筛查时,研究对象年龄<30岁时推荐使用Sadeh算法,≥30岁时推荐使用Cole-Kripke算法,且均需要睡眠日记的辅助。研究为24 h活动行为研究提供了数据处理方面的建议,也为未来开发新的清醒-睡眠期分离方法提供了方向,但仍需更多的研究来比较与验证这些睡眠筛查方法,以促进研究方法的标准化。

In the study of 24 h activity behaviors based on accelerometry,it is essential to distinguish accelerometer data into wake periods(for analyzing physical activity and sedentary behavior) and sleep periods(for examining sleep duration and quality) before calculating different activity behavior times.However,there is no widely accepted standard method for separating wake-sleep periods in accelerometer data,and a systematic review of these methods is lacking.This study identifies nine wake-sleep separation methods applicable under free-living conditions from 425 relevant papers.By elucidating the principles,advantages,and limitations of these methods,the study provides recommendations for researchers using GT3X/± accelerometers:1) For selecting automatic sleep screening algorithms,wrist-worn devices should use the sleep diary/HDCZA algorithm built into GGIR combined with the van Hees 2015 algorithm,while waist-worn devices can use the Tracy ProChildren,Tudor-Locke,McVeigh,or Bellettiere-McVeigh algorithms;2) when using Actilife for sleep screening,the Sadeh algorithm is recommended for individuals under 30 years old,and the Cole-Kripke algorithm for those aged 30 and above,both requiring the support of a sleep diary.This study provides data processing recommendations for 24 h activity behavior research and offers direction for developing new wake-sleep separation methods in the future.Nonetheless,more research is needed to compare and validate these sleep screening methods to promote the standardization of research methods.
