COVID-19疫情爆发后中国四川地区普通居民睡眠变化的研究

Research on Sleep Changes of Ordinary Residents in Western China after Outbreak of COVID-19

目的COVID-19疫情的全球大流行对人类健康造成巨大影响。本研究调查COVID-19疫情流行后中国四川地区普通居民睡眠的变化情况。方法对来自四川大学华西医院自然人群队列的6196例成年人的睡眠数据进行分析。基线数据收集于2019年5月14日至11月21日,随访数据收集于2020年12月8日至2021年2月23日,即中国COVID-19疫情爆发和封锁期前后约9个月。结果COVID-19疫情流行后,人们就寝时间更早(中位数22∶30对比22∶00,P<0.001),清晨醒转时间更晚(中位数6∶30对比7∶00,P<0.001),睡眠潜伏期更短(27.1min对比23.9min,P<0.01)。COVID-19疫情流行前后,普通居民主观睡眠质量相当(P=0.991),流行后白天思睡和疲劳均有所改善(P<0.001)。≥60岁人群较<60岁人群睡得早(P=0.001),醒得晚(P<0.001)。女性较男性醒的更晚(P=0.035),睡眠质量改善更为显著(P=0.022)。结论COVID-19疫情流行后,中国四川地区居民睡眠行为更加健康,整体睡眠质量有所改善。女性和老年人的睡眠质量有了较大提高。

Aim To investigate the impact of COVID-19 on sleep among ordinary residents in western China.Methods The sleep data of 6196 adults from the General Population cohort of West China Hospital,Sichuan University were analyzed.The baseline data were collected from May 14,2019 to November 21,2019,and the follow-up data were collected from December 8,2020 to February 23,2021,nearly 9 months before and after the outbreak and lockdown period of COVID-19 in China.Results During the COVID-19 pandemic,people went to bed earlier(median 22:30 vs.22:00,P<0.001),woke up later(median 6:30 vs.7:00,P<0.001),and took less time to fall asleep(27.1 vs.23.9 minutes,P<0.01).The subjective sleep quality of ordinary residents was similar before and after the COVID-19epidemic(P=0.991),but sleepiness and fatigue were improved after the COVID-19 epidemic(P<0.001).The elderly(≥60 years)went to bed earlier(P=0.001)and woke up later(P<0.001)than the young(<60 years).Women woke up later than men(P=0.035),and the improvement of sleep quality was more obvious(P=0.022).Conclusion After the COVID-19 pandemic,residents in western China have become healthier in sleep behavior and the overall sleep quality has improved.The sleep quality of women and the elderly has been greatly improved.
