Abstract Background: The COVID-19 pandemic has spread worldwide and has attracted considerable attention. This study aims to investigate the sleep quality of the public during the normalization of COVID-19 pandemic prevention and control in China, as well as related factors that affect sleep quality. Methods: A web-based cross-sectional survey was implemented from Feb 2nd to Feb 9th, 2021 in China. A total of 613 subjects from 27 provinces and 4 municipalities participated in this study. Questionnaire including Pittsburgh Sleep Quality Index (PSQI), COVID Stress Scale (CSS), COVID-19 Worry Scale and 14-item Resilience Scale (the RS-14) as well as demographic characteristics and pandemic-related information was used to measure sleep quality, stress, worries and resilience of Chinese population. Hierarchical multiple regression analysis was conducted to explore the associated factors of sleep quality.Results: The prevalence of poor sleep quality among 613 participants was 41.1% (95%CI=37.2%-45%). Regression analysis indicated that chronic diseases, medical visits, occupation, and negative life events were factors affecting sleep quality. Stress and worries were positively associated with score of sleep quality, while resilience was negatively associated with score of sleep quality. Conclusions: During the normalization of COVID-19 pandemic prevention and control, Chinese public has poor sleep quality. Effective interventions should be taken to decrease people’s COVID-19 stress and worries. Resilience enhancement is also an important factor to be considered to improve people’s sleep quality.
