Abstract

PURPOSE

To evaluate the validity and the reliability of the Oura Ring Generation 3 (Gen3) with Oura Sleep Staging Algorithm 2.0 (OSSA 2.0) through multi-night polysomnography (PSG).

PARTICIPANTS AND METHODS

Participants were 96 generally healthy Japanese men and women aged between 20 and 70 years contributing with 421,045 30-s epochs. Sleep scoring was performed according to American Academy of Sleep Medicine criteria. Each participant could contribute with a maximum of three polysomnography (PSG) nights. Within-participant means were created for each sleep measure and paired t-tests were used to compare equivalent measures obtained from the PSG and Oura Rings (non-dominant and dominant hand). Agreement between sleep measures were assessed using Bland-Altman plots. Interrater reliability for epoch accuracy was determined by prevalence-adjusted and bias-adjusted kappa (PABAK).

RESULTS

The Oura Ring did not significantly differ from PSG for the measures time in bed, total sleep time, sleep onset latency, sleep period time, wake after sleep onset, time spent in light sleep, and time spent in deep sleep. Oura Rings worn on the non-dominant- and dominant-hand underestimated sleep efficiency by 1.1 %-1.5 % and time spent in REM sleep by 4.1-5.6 min. The Oura Ring had a sensitivity of 94.4 %-94.5 %, specificity of 73.0 %-74.6 %, a predictive value for sleep of 95.9 %-96.1 %, a predictive value for wake of 66.6 %-67.0 %, and accuracy of 91.7 %-91.8 %. PABAK was 0.83-0.84 and reliability was 94.8 %. Sleep staging accuracy ranged between 75.5 % (light sleep) and 90.6 % (REM sleep).

CONCLUSIONS

The Oura Ring Gen3 with OSSA 2.0 shows good agreement with PSG for global sleep measures and time spent in light and deep sleep.

摘要

目的

通过多晚多导睡眠图（PSG）评估 Oura Ring Gen3 和 Oura 睡眠分期算法 2.0（OSSA 2.0）的有效性和可靠性。

参与者和方法

共有 96 名年龄在 20 至 70 岁之间的一般健康的日本男性和女性参与，共贡献了 421,045 个 30 秒的睡眠片段。睡眠评分按照美国睡眠医学学会的标准进行。每位参与者最多可以贡献三个多导睡眠图（PSG）夜的数据。为每个睡眠指标创建了参与者内均值，并使用配对 t 检验比较了从 PSG 和 Oura 戒指（非优势手和优势手）获得的等效指标。使用 Bland-Altman 图评估睡眠指标的一致性。通过调整流行率和偏倚的 kapp 值（PABAK）来确定 epoch 准确性的组内可靠性。

结果

Oura Ring 在以下指标上与 PSG 无显著差异：床上时间、总睡眠时间、睡眠潜伏期、睡眠周期时间、睡眠后觉醒时间、浅睡眠时间和深睡眠时间。佩戴在非优势手和优势手上的 Oura Ring 分别低估了睡眠效率 1.1%-1.5%和 REM 睡眠时间 4.1-5.6 分钟。Oura Ring 的灵敏度为 94.4%-94.5%，特异性为 73.0%-74.6%，睡眠预测值为 95.9%-96.1%，觉醒预测值为 66.6%-67.0%，准确率为 91.7%-91.8%。PABAK 为 0.83-0.84，可靠性为 94.8%。睡眠分期准确性在 75.5%（浅睡眠）至 90.6%（REM 睡眠）之间。
