This study aimed to determine the feasibility of using a wrist-based fitness tracking device to assess sleep among Obstetrics and Gynecology (OBGYN) trainees who engaged in a yoga-based wellness program. We also sought to evaluate the effects of yoga on sleep.
A quality improvement initiative consisting of an 8-week wellness program of weekly yoga classes, nutrition, and physical challenges was implemented for OBGYN residents and Maternal-Fetal Medicine fellows. The Polar A370 fitness tracker device was provided and synced to the Polar Flow for Coach program for inclusion. Data obtained included total and restful sleep from each night the device were worn. Pre- and post-assessment of the Pittsburg Sleep Quality Index (PSQI) were compared. Linear mixed models were used to estimate and test the effect of yoga on sleep while controlling for on-call shifts.
Of the 15 participants who synced their device, 13 (87%) were included for analysis. Sleep data from 572 nights were analyzed. The mean (SD) total sleep was 434.28 (110.03) minutes over the 8 weeks. A minimum of 7 hours (420 minutes) of total sleep occurred 59.3% of the time. After controlling for Friday or Saturday night on-call, those who attended yoga class had a significantly greater total sleep (yoga: 425.14 minutes [41.89], no yoga: 357.33 [43.04] minutes; = 0.04). There was no significant change in the mean global PSQI score after the program (pre: 5.0 [1.6], post: 5.1 [2.5], = 0.35).
Wearable fitness monitors provide insight into sleep patterns displayed during training and can serve as a tool to identify those who are sleep deprived and assist in the evaluation of trainee wellness. Training programs are encouraged to provide access to yoga and mindfulness interventions to improve sleep and possibly clinical performance.
· Yoga improves trainee sleep by approximately 60 minutes.. · Total and restful sleep are reduced during night float rotation.. · Trainees obtained 7 hours of sleep approximately 60% of the time..
本研究旨在确定使用腕部健身追踪设备评估参与基于瑜伽的健康计划的妇产科（OBGYN）实习生睡眠情况的可行性。我们还试图评估瑜伽对睡眠的影响。
为妇产科住院医师和母胎医学研究员实施了一项质量改进计划，该计划包括为期8周的健康计划，每周进行瑜伽课程、营养指导和身体挑战。提供了 Polar A370 健身追踪器设备，并将其与 Polar Flow for Coach 计划同步以纳入研究。获得的数据包括佩戴设备的每个夜晚的总睡眠时间和安稳睡眠时间。比较了匹兹堡睡眠质量指数（PSQI）的前后评估结果。使用线性混合模型来估计和测试瑜伽对睡眠的影响，同时控制值班轮班情况。
在15名同步设备的参与者中，13名（87%）被纳入分析。分析了来自572个夜晚的睡眠数据。在8周内，平均（标准差）总睡眠时间为434.28（110.03）分钟。至少7小时（4
