Our study aimed to assess the change in the sleep patterns during the Coronavirus lockdown in five regions (Austria/Germany, Ukraine, Greece, Cuba and Brazil), using online surveys, translated in each language. Part of the cohort (age 25-65, well-educated) was collected directly during lockdown, to which retrospective cross-sectional data from and after lockdown (retrospective) questionnaires were added. We investigated sleep times and sleep quality changes from before to during lockdown and found that, during lockdown, participants had (i) worse perceived sleep quality if worried by COVID-19, (ii) a shift of bedtimes to later hours during workdays, and (iii) a sleep loss on free days (resulting from more overall sleep during workdays in non-system relevant jobs), leading to (iv) a marked reduction of social jetlag across all cultures. For further analyses we directly compared system relevant and system irrelevant jobs, because it was assumed that the nature of the lockdown's consequences is dependent upon system relevance. System relevant jobs were found to have earlier wake-up times as well as shorter total sleep times on workdays, leading to higher social jetlag for people in system relevant jobs. Cultural differences revealed a general effect that participants from Greece and Ukraine had later bedtimes (on both work and free days) and wake-up times (on workdays) than Cuba, Brazil and Austria, irrespective of COVID-19 lockdown restrictions.
我们的研究旨在使用在线调查评估五个地区（奥地利/德国、乌克兰、希腊、古巴和巴西）在冠状病毒封锁期间睡眠模式的变化，这些调查已被翻译成每种语言。部分队列（年龄在 25-65 岁之间，受过良好教育）是在封锁期间直接收集的，之后又添加了封锁期间和之后的回溯性横断面数据（回溯性）问卷。我们调查了睡眠时间和睡眠质量在封锁前到封锁期间的变化，发现，在封锁期间，参与者（i）如果担心 COVID-19，睡眠质量更差；（ii）工作日的睡眠时间推迟；（iii）休息日的睡眠时间减少（这是由于非系统相关工作的工作日睡眠时间增加）；（iv）所有文化的社交时差明显减少。为了进一步分析，我们直接比较了系统相关和系统不相关的工作，因为我们假设封锁的后果性质取决于系统相关性。结果显示，系统相关工作的工作日起床时间更早，总睡眠时间更短，导致系统相关工作的人社交时差更高。文化差异揭示了一个普遍的影响，即来自希腊和乌克兰的参与者的就寝时间（工作日和休息日）以及起床时间（工作日）比古巴、巴西和奥地利晚，无论 COVID-19 封锁限制如何。
