The objective of the present study was to investigate the relationship between chronotype, lifestyle habits during the pandemic, and changes in sleep timing during the first wave of the COVID-19 pandemic in youth.
An online survey of adolescents and young adults (N = 449) was conducted in June 2020. Multivariate hierarchical regressions assessed the contribution of chronotype and changes in lifestyle habits to sleep timing during the COVID-19 pandemic in two age groups (12 to 17 years old and 18 to 25 years old).
Chronotype was a significant predictor of changes in sleep habits during the pandemic in both age groups. In adolescents, electronic device usage during the pandemic was a significant predictor of bedtimes and wake times on weekdays, and caffeine during the pandemic was a predictor of weekday wake times. The number of hours worked during the pandemic was a significant predictor of weekday wake times in both age groups. In young adults, cannabis consumption during the pandemic was a predictor of weekend bedtimes. A later chronotype, along with higher usage of electronic devices, fewer hours worked, as well as higher caffeine and cannabis consumption during the pandemic were associated with delayed sleep timing during the pandemic in youth.
These results highlight the importance of assessing lifestyle habits when exploring changes in sleep habits in youth.
本研究旨在探讨青少年在新冠疫情第一波期间的睡眠时相关的昼夜型、疫情期间的生活习惯变化的关系。
2020 年 6 月,对青少年和年轻人(N=449)进行了在线调查。采用多元分层回归分析,在两个年龄组(12-17 岁和 18-25 岁)中评估昼夜型和生活习惯变化对新冠疫情期间睡眠时相关的影响。
昼夜型是两个年龄组在疫情期间睡眠习惯变化的重要预测因子。在青少年中,疫情期间电子设备的使用是工作日睡眠时间和起床时间的重要预测因子,而疫情期间摄入的咖啡因是工作日起床时间的预测因子。疫情期间工作的小时数是两个年龄组工作日起床时间的重要预测因子。在年轻人中,疫情期间摄入大麻是周末睡眠时间的预测因子。昼夜型较晚、疫情期间电子设备使用较多、工作时间较少,以及咖啡因和大麻摄入较多与青少年在疫情期间睡眠时相关的延迟有关。
这些结果强调了在探索青少年睡眠习惯变化时评估生活习惯的重要性。
