可穿戴设备在大规模纵向测量睡眠方面具有巨大的潜力，但其准确性还需要验证。我们比较了多传感器Oura环(Oura Health Oy，Oulu，芬兰)与多导睡眠图(PSG)和健康青少年研究活动仪的性能。53名青少年(28名女性，年龄15-19岁)在佩戴Oura戒指和Actiwatch 2(飞利浦呼吸电子产品，美国)的情况下进行了夜间PSG监测。测量是在多个晚上进行的，涉及三个睡眠水平(5个晚上的睡眠时间为6.5或8小时，3个晚上的睡眠时间为9小时)。分析了两种灵敏度设置下的Actiwatch数据。使用Bland-Altman曲线图和逐个纪元(EBE)分析来评估估计的睡眠测量以及睡眠觉醒和睡眠阶段协议的差异。与PSG相比，在不同的TiB条件下，Oura始终将TST低估了32.8%至47.3min(P<；0.001)；Actiwatch 2在其默认设置下将TST低估了25.8%至33.9min。Oura严重高估了WASO，平均高估了30.7到46.3分钟。在6.5和8h的TiB条件下，它与Actiwatch 2的默认灵敏度相当。与PSG相比，Oura显著低估了REM睡眠(12.8至19.5分钟)和轻度睡眠(51.1至81.2分钟)，但高估了N3 31.5至46.8分钟(P<；0.01)。欧洲教育局的分析显示，所有TIB的睡眠唤醒准确性、特异性和敏感度都很高，在0.88到0.89之间。在Oura环的默认设置下，其睡眠测量结果与研究级活动记录仪相当。睡眠分期需要改进。然而，该设备似乎足以表征睡眠持续时间操纵对青少年睡眠宏观结构的影响。
Wearable devices have tremendous potential for large-scale longitudinal measurement of sleep, but their accuracy needs to be validated. We compared the performance of the multisensor Oura ring (Oura Health Oy, Oulu, Finland) to polysomnography (PSG) and a research actigraph in healthy adolescents. Fifty-three adolescents (28 females; aged 15–19 years) underwent overnight PSG monitoring while wearing both an Oura ring and Actiwatch 2 (Philips Respironics, USA). Measurements were made over multiple nights and across three levels of sleep opportunity (5 nights with either 6.5 or 8h, and 3 nights with 9h). Actiwatch data at two sensitivity settings were analyzed. Discrepancies in estimated sleep measures as well as sleep-wake, and sleep stage agreements were evaluated using Bland–Altman plots and epoch-by-epoch (EBE) analyses. Compared with PSG, Oura consistently underestimated TST by an average of 32.8 to 47.3 minutes (Ps < 0.001) across the different TIB conditions; Actiwatch 2 at its default setting underestimated TST by 25.8 to 33.9 minutes. Oura significantly overestimated WASO by an average of 30.7 to 46.3 minutes. It was comparable to Actiwatch 2 at default sensitivity in the 6.5, and 8h TIB conditions. Relative to PSG, Oura significantly underestimated REM sleep (12.8 to 19.5 minutes) and light sleep (51.1 to 81.2 minutes) but overestimated N3 by 31.5 to 46.8 minutes (Ps < 0.01). EBE analyses demonstrated excellent sleep-wake accuracies, specificities, and sensitivities – between 0.88 and 0.89 across all TIBs. The Oura ring yielded comparable sleep measurement to research grade actigraphy at the latter’s default settings. Sleep staging needs improvement. However, the device appears adequate for characterizing the effect of sleep duration manipulation on adolescent sleep macro-architecture.
