Abstract

STUDY OBJECTIVES

Social jetlag, the difference between imposed and endogenous sleep schedules, may be detrimental to resident physicians' health. The current profiles of sleep habits, particularly the differences between workdays and free days, are unknown in that population. This cross-sectional study of Quebec resident physicians aimed at assessing sleep habits on workdays and free days and predictors of social jetlag.

METHODS

Residents were recruited via their residency programs and social media to complete an online questionnaire. Measures included means of sleep duration and timing, chronotype, sleep debt, sleep disturbances, and social jetlag. A range of sociodemographic variables, lifestyle characteristics, and mental health indicators were examined as predictors of severe social jet lag using logistic regressions.

RESULTS

A total of 492 residents were included in the study (mean [standard deviation] age, 27.6 [3.6] years; 330 females [67.1%]). The mean sleep duration was 7.15 hours (95% confidence interval [CI], 7.02-7.28 hours) on workdays and 8.36 hours (95% CI, 8.18-8.54 hours) on free days. The mean sleep debt was 1.59 hours (95% CI, 1.37-1.81 hours), and mean social jetlag was 1.37 hours (95% CI, 1.28-1.47 hours), with 31.9% (95% CI, 25.0-39.6%) of residents experiencing ≥2 hours of sleep debt and 21.8% (95% CI, 16.5-28.3%) experiencing severe social jetlag. The prevalence of sleep disturbances was 51.7% (95% CI, 44.4-58.8%). Severe social jetlag was associated with earlier stage of training, later chronotype, decreased physical activity, increased sleep debt, and depressive symptoms.

CONCLUSIONS

Many residents experience severe social jetlag, chronic sleep deprivation, and sleep disturbances. Importantly, severe social jetlag was associated with depressive symptoms, suggesting a potential intervention target for promoting residents' mental health.

摘要

研究目的

社交时差，即强制睡眠时间表与内源性睡眠时间表之间的差异，可能对住院医师的健康有害。该人群目前的睡眠习惯概况，尤其是工作日和休息日之间的差异尚不清楚。这项针对魁北克住院医师的横断面研究旨在评估工作日和休息日的睡眠习惯以及社交时差的预测因素。

方法

通过住院医师培训项目和社交媒体招募住院医师，以完成一份在线问卷。测量指标包括睡眠时间和时间安排的均值、昼夜节律类型、睡眠债、睡眠障碍和社交时差。使用逻辑回归分析一系列社会人口统计学变量、生活方式特征和心理健康指标，作为严重社交时差的预测因素。

结果

共有492名住院医师纳入研究（平均[标准差]年龄，27.6[3.6]岁；330名女性[67.1%]）。工作日的平均睡眠时间为7.15小时（95%置信区间[CI]，7.02 - 7.28小时），休息日为8.36小时（95%CI，8.18 - 8.54小时）。平均睡眠债为1.59小时（95%CI，1.37 - 1.81小时），平均社交时差为1.37小时（95%CI，1.28 - 1.47小时），31.9%（95%CI，25.0 - 39.6%）的住院医师睡眠债≥2小时，21.8%（95%CI，16.5 - 28.3%）经历严重社交时差。睡眠障碍的患病率为51.7%（95%CI，44.4 - 58.8%）。严重社交时差与培训阶段较早、昼夜节律类型较晚、身体活动减少、睡眠债增加和抑郁症状有关。
