The coronavirus disease 2019 (COVID-19) pandemic has greatly changed our daily life. Owing to the imposed restrictions, many educational facilities have introduced remote teaching. This study aims to clarify the association between remote teaching and Japanese university students' sleeping habits.
The participants were medical students at Aichi Medical University. We used data from an ongoing longitudinal sleeping habits survey. For the participants who enrolled in the university during 2018-2020, multilevel analyses of sleep duration during weekdays and weekends across 3 years were conducted, adjusting for sex, grade, place of stay, sleep problems and lifestyle habits.
Among the students enrolled in the university, the data of 677 in 2018, 657 in 2019, and 398 in 2020 was available for analysis. The mean sleep duration during weekdays (in minutes) was 407.6 ± 60.3 in 2018, 406.9 ± 63.0 in 2019, and 417.3 ± 80.9 in 2020. The mean sleep duration during weekends (in minutes) was 494.5 ± 82.5 in 2018, 488.3 ± 87.9 in 2019, and 462.3 ± 96.4 in 2020. Multilevel analysis conducted for the 684 participants who enrolled during 2018-2020 showed that sleep duration during weekdays was associated with the place of stay and survey year. Moreover, students reported significantly longer sleep duration during weekdays in 2020 than in 2019, but no significant difference in sleep duration was found between 2018 and 2019. The other multilevel analysis found sleep duration during weekends to be associated with the survey year, sex and always doing something before going to bed. Sleep duration during weekends was shorter in 2020 than in 2019 and longer for male students and students who always do something before going to bed. Ten students were reported to have a delayed sleep phase in 2020.
Students' sleep duration increased during weekdays and decreased during weekends in 2020. This difference could be explained by the COVID-19 pandemic and the introduction of remote teaching.
2019年冠状病毒病（COVID-19）大流行极大地改变了我们的日常生活。由于实施了限制措施，许多教育机构采用了远程教学。本研究旨在阐明远程教学与日本大学生睡眠习惯之间的关联。
参与者为爱知医科大学的医学生。我们使用了一项正在进行的关于睡眠习惯的纵向调查数据。对于在2018 - 2020年期间入学的参与者，对3年中工作日和周末的睡眠时间进行了多水平分析，并对性别、年级、居住地点、睡眠问题和生活方式习惯进行了调整。
在该大学入学的学生中，2018年有677人、2019年有657人、2020年有398人的数据可供分析。工作日的平均睡眠时间（分钟）在2018年为407.6±60.3，2019年为406.9±63.0，2020年为417.3±80.9。周末的平均睡眠时间（分钟）在2018年为494.5±82.5，2019年为488.3±87.9，2020年为462.3±96.4。对2018 - 2020年期间入学的684名参与者进行的多水平分析表明，工作日的睡眠时间与居住地点和调查年份有关。此外，学生报告称2020年工作日的睡眠时间比2019年显著延长，但2018年和2019年之间的睡眠时间没有显著差异。另一项多水平分析发现，周末的睡眠时间与调查年份、性别以及睡前总是做某事有关。2020年周末的睡眠时间比2019年短，男性学生以及睡前总是做某事的学生睡眠时间更长。据报告，2020年有10名学生出现睡眠时相延迟。
2020年学生的睡眠时间在工作日增加，在周末减少。这种差异可能由COVID-19大流行和远程教学的引入来解释。
