本研究探讨了时间类型依赖的耐受性的要求，工作的早晨，傍晚，夜班的社会时差，睡眠时间，睡眠障碍。采用慕尼黑倒班工人时间类型问卷（MCTQ（倒班））对238名倒班工人进行了时间类型分析，该问卷收集了倒班相关睡眠持续时间和睡眠时间的信息。此外，94名轮班工人还完成了标准轮班工作指数（SSI）的睡眠问卷中评估睡眠障碍的项目。虽然所有的参与者都上早班、晚班和夜班，但子样本的旋转方向和速度不同。睡眠持续时间，社会时差，睡眠障碍都显着调制的相互作用的时间型和转变（混合模型方差分析）。较早的生理时钟类型显示，夜班期间睡眠时间缩短，社交时差增加，睡眠障碍程度也更高。在早班期间，也观察到了类似的模式。年龄本身只影响睡眠时间和质量本身，而没有显示与变化的相互作用。我们发现，在快速轮班制下，工人们睡得更久。由于时间型随年龄变化，睡眠行为和昼夜失调的轮班工人的调查必须考虑时间型，以充分了解个体间和个体内的变异，特别是在目前的人口变化。考虑到睡眠对健康的影响，我们的研究结果强调了时间类型在理解轮班工作对睡眠的影响和设计解决方案以减少轮班工作相关健康问题方面的重要性。
This study explores chronotype-dependent tolerance to the demands of working morning, evening, and night shifts in terms of social jet lag, sleep duration, and sleep disturbance. A total of 238 shift-workers were chronotyped with the Munich ChronoType Questionnaire for shift-workers (MCTQ(Shift)), which collects information about shift-dependent sleep duration and sleep timing. Additionally, 94 shift-workers also completed those items of the Sleep Questionnaire from the Standard Shift-Work Index (SSI) that assess sleep disturbances. Although all participants worked morning, evening, and night shifts, subsamples differed in rotation direction and speed. Sleep duration, social jet lag, and sleep disturbance were all significantly modulated by the interaction of chronotype and shift (mixed-model ANOVAs). Earlier chronotypes showed shortened sleep duration during night shifts, high social jet lag, as well as higher levels of sleep disturbance. A similar pattern was observed for later chronotypes during early shifts. Age itself only influenced sleep duration and quality per se, without showing interactions with shifts. We found that workers slept longer in fast, rotating shift schedules. Since chronotype changes with age, investigations on sleep behavior and circadian misalignment in shift-workers have to consider chronotype to fully understand interindividual and intraindividual variability, especially in view of the current demographic changes. Given the impact of sleep on health, our results stress the importance of chronotype both in understanding the effects of shift-work on sleep and in devising solutions to reduce shift-work-related health problems.
