| 【Abstract】 Background The sudden onset of major public health emergencies may lead to significant alterations in individuals' sleep hygiene habits, consequently impacting their overall sleep quality. Objective Exploring the relationship between the sleep quality and sleep hygiene among Chinese adult residents during the major public health emergencies. In order to provide reference for improving the sleep quality of residents during such events. Methods From 20 February to 29 February 2020, a convenient sampling method was employed to select 1,364 Chinese adult residents as the research subjects. The self-designed questionnaire included basic-demographic information and the impact of the pandemic on sleep hygiene of Chinese adult residents. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. PSQI score ≥8 indicates poor sleeper. Binary logistic regression analysis was conducted to identify related factors of sleep quality. Radar charts were used to display the sleep hygiene between poor sleepers and good sleepers. Results During the major public health emergencies, 473 of 1 364 residents (34.68%) showed poor sleep quality. Comparsion of two groups of residents with good or poor sleep quality revealed statistically difference in age (χ2=3.887), medical history (χ2=27.938), importance attached to sleep before major public health emergencies (χ2=4.337), impact of sleep quality on life during the major public health emergencies (χ2=178.138), frequency of staying up late during the major public health emergencies (χ2=139.390), sleep compensation (χ2=39.257), impact of sleep problems on daytime energy (χ2=285.879), changes of bedtime (χ2=63.031), sleep latency (χ2=168.672), wake-up time (χ2=59.221), sleep duration (χ2=172.332) and time spent in the bedroom (χ2=23.071), and amount spent on changing sleep environment (χ2=58.584), with significance levels at P<0.05 or 0.01. Logistic regression analysis revealed that medical history (OR=1.680, 95% CI: 1.185~2.382), impact of sleep quality on life during the major public health emergencies (OR=4.181, 95% CI: 2.722~6.422), frequency of staying up late during the major public health emergencies, 3~4 times per week (OR=3.145, 95% CI: 1.497~6.605); almost every day (OR=4.271, 95% CI: 1.970~9.260), impact of sleep problems on daytime energy (OR=7.169, 95% CI: 5.188~9.907), prolonged sleep latency (OR=2.836, 95% CI=2.019~3.982), shortened sleep duration (OR=3.518, 95% CI: 2.144~5.772), and amount spent on changing sleep environment ≤499 RMB (OR=0.334, 95% CI: 0.134~0.830) were related factors of poor sleep quality. Poor sleepers exhibited more worries and excessive cleaning behaviors during the major public health emergencies. Compared to good sleepers, poor sleepers had more unhealthy sleep hygiene and were more likely to stay up late due to stress and emotional issues. Conclusion Chinese residents are facing poor sleep quality during the major public health emergencies. Poor sleep hygiene habits during the pandemic had a significant impact on sleep quality. |
