Few studies have yet examined sleep quality among puerperal women during the coronavirus disease 2019 (COVID-19) pandemic. This cross-sectional study aimed to compare the sleep quality of puerperal women before and during the COVID-19 pandemic in Lanzhou, China. The study exploreed the factors that affect sleep quality among puerperal women.
The study population comprised puerperal women who went to the obstetric department of the Gansu Provincial Maternity and Childcare Hospital on the 42nd day after childbirth. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Data were collected by doctors in the obstetric department before the COVID-19 pandemic (Oct.–Dec. 2019) and during the COVID-19 pandemic (Feb.–Apr. 2020) in China. Multiple linear regressions were used to examine the association between the sleep quality of puerperal women and COVID-19 and to identify factors that affect the total PSQI scores.
In 2019, 546 puerperal women were assessed compared with 655 who were assessed in 2020. Compared with before COVID-19, the total PSQI scores of puerperal women improved during the COVID-19 pandemic. In addition, the influencing factors of sleep quality among puerperal women were the pandemic itself, age, conception method, and postpartum depression (PPD).
In contrast with other studies, there was no evidence for worsening sleep quality of puerperal women during the COVID-19 pandemic in Lanzhou, China. Puerperal women who underwent assisted pregnancy or developed PPD were more likely to experience poor sleep quality.
