Increasingly, behavioral and epidemiological research uses activity-based measurements (accelerometry) to provide objective estimates of physical activity, sedentary behavior, and sleep in a variety of study designs. As interest in concurrently assessing these domains grows, there are key methodological considerations that influence the choice of monitoring instrument, analysis algorithm, and protocol for measuring these behaviors. The purpose of this review is to summarize evidence-guided information for 7 areas that are of importance in the design and interpretation of studies using actigraphy: (1) choice of cut-points; (2) impact of epoch length; (3) accelerometer placement; (4) duration of monitoring; (5) approaches for distinguishing sleep, nonwear times, and sedentary behavior; (6) role for a sleep and activity diary; and (7) epidemiological applications. Recommendations for future research are outlined and are intended to enhance the appropriate use of accelerometry for assessing physical activity, sedentary behavior, and sleep behaviors in research studies.
越来越多的行为和流行病学研究采用基于活动的测量方法（加速度计），以便在各种研究设计中对身体活动、久坐行为和睡眠进行客观评估。随着同时评估这些领域的兴趣不断增加，在监测仪器、分析算法以及测量这些行为的方案选择方面，存在一些关键的方法学考量。本综述的目的是总结在使用活动记录仪的研究设计和解读中，对7个重要领域具有指导作用的证据：（1）切点的选择；（2）时段长度的影响；（3）加速度计的放置；（4）监测持续时间；（5）区分睡眠、非佩戴时间和久坐行为的方法；（6）睡眠和活动日记的作用；（7）流行病学应用。文中概述了对未来研究的建议，旨在促进在研究中更恰当地使用加速度计来评估身体活动、久坐行为和睡眠行为。
