Investigation on sleep quality in Chinese medical staff during the COVID-19 pandemic.

ABSTRACT

The aims of this study were to evaluate the situation of sleep quality among Chinese medical staff during the coronavirus disease 2019 (COVID-19) pandemic. We used the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality among medical staff from 8 May 2020 to 22 May 2020 in People's Republic of China. A total of 101 (25%) participants were poor sleepers, while 303 (75%) were good sleepers, as defined by PSQI. The PSQI scores were higher in high age, married, master/doctor, nurse, and frequent night shifts groups when compared with those in middle and low age, unmarried and divorced/widowed, bachelor or below, clinician and other job, low frequency night shifts, respectively (all p < 0.01). Multiple linear regression analysis showed that higher PSQI score was positively associated with higher educational background, age, and more frequent night shifts (all p < 0.001). Sleep quality of medical staff should be improved, especially for high age, married, master/doctor, nurse, and frequent night shifts groups.
