充足的睡眠、锻炼和限制久坐活动可以大大有助于疾病预防和整体健康和长寿。测量完整的24小时活动周期-睡眠，久坐行为（SED），轻度体力活动（LPA）和中度到剧烈体力活动（MVPA）-现在可以使用小型可穿戴设备。这项研究比较了9种设备在24小时活动测量中的准确性。成年人（N=40，47%男性）佩戴9种设备24小时：Actigraph GT 3X+、activPAL、Fitbit One、GENEactiv、Jawbone Up、LUMOback、Nike Fuelband、Omron计步器和Z-Machine。对总睡眠时间（Z-机）、SED（activPAL）、LPA（GT 3x+）、MVPA（GT 3x+）和步数（Omron）花费的时间进行比较（与标准）。分析包括平均绝对误差百分比、等效性检验和Bland-Altman图。睡眠的错误率范围为8.1-16.9%; SED为9.5-65.8%; LPA为19.7-28.0%; MVPA为51.8-92%;步数为14.1-29.9%。等效性测试表明，只有两项比较与标准显著等效：LUMOback用于久坐行为，GT 3X+用于睡眠。Bland-Altman图表明，GT 3X+对睡眠的测量结果最接近，LUMOback对久坐行为的测量结果最接近，GENEactiv对LPA的测量结果最接近，Fitbit对MVPA的测量结果最接近，GT 3X+对步数的测量结果最接近。目前，没有设备可以准确地捕获整个24小时的活动数据，但未来的活动测量应该以准确的24小时测量为目标。研究人员应继续根据他们感兴趣的主要结果选择测量设备。
Getting enough sleep, exercising and limiting sedentary activities can greatly contribute to disease prevention and overall health and longevity. Measuring the full 24-hour activity cycle - sleep, sedentary behavior (SED), light intensity physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) - may now be feasible using small wearable devices. This study compares nine devices for accuracy in 24-hour activity measurement. Adults (N=40, 47% male) wore nine devices for 24-hours: Actigraph GT3X+, activPAL, Fitbit One, GENEactiv, Jawbone Up, LUMOback, Nike Fuelband, Omron pedometer, and Z-Machine. Comparisons (to standards) were made for total sleep time (Z-machine), time spent in SED (activPAL), LPA (GT3x+), MVPA (GT3x+), and steps (Omron). Analysis included mean absolute percent error, equivalence testing, and Bland-Altman plots. Error rates ranged from 8.1–16.9% for sleep; 9.5–65.8% for SED; 19.7–28.0% for LPA; 51.8–92% for MVPA; and 14.1–29.9% for steps. Equivalence testing indicated only two comparisons were significantly equivalent to standards: the LUMOback for sedentary behavior and the GT3X+ for sleep. Bland-Altman plots indicated GT3X+ had the closest measurement for sleep, LUMOback for sedentary behavior, GENEactiv for LPA, Fitbit for MVPA and GT3X+ for steps. Currently, no device accurately captures activity data across the entire 24-hour day, but the future of activity measurement should aim for accurate 24-hour measurement as a goal. Researchers should continue to select measurement devices based on their primary outcomes of interest.
