Sedentary time (too much sitting) increasingly is being recognized as a distinct health risk behavior. This paper reviews the reliability and validity of self-reported and device-based sedentary time measures and provides recommendations for their use in population-based studies. The focus is on instruments that have been used in free-living, population-based research in adults. Data from the 2003-2006 National Health and Nutrition Examination Survey are utilized to compare the descriptive epidemiology of sedentary time that arises from the use of different sedentary time measures. A key recommendation from this review is that, wherever possible, population-based monitoring of sedentary time should incorporate both self-reported measures (to capture important domain- and behavior-specific sedentary time information) and device-based measures (to measure both total sedentary time and patterns of sedentary time accumulation).
久坐时间（即坐得太久）越来越被认为是一种明显的健康风险行为。本文综述了自评式和仪器式久坐时间测量方法的信度和效度，并就其在基于人群的研究中的应用提出了相关建议。本研究重点关注那些已被应用于成年人自由生活、基于人群的研究中的仪器。文中使用了 2003-2006 年全国健康与营养调查的数据，对不同久坐时间测量方法得出的久坐时间描述性流行病学数据进行了比较。本综述的一个重要建议是，只要有可能，基于人群的久坐时间监测应同时采用自评式测量方法（以获取特定领域和行为的重要久坐时间信息）和仪器式测量方法（以测量总久坐时间和久坐时间积累模式）。
