Objectives: To investigate the mental status of pregnant women and to describe their obstetrical choices during the outbreak of COVID-19. Design: A cross-sectional study. Setting: Wuhan and Chongqing, two different epidemic areas. Population: A total of 1947 valid questionnaires were received. Methods: We collected information on demographic, pregnancy, and epidemic, along with their attitudes towards the epidemic, anxiety status and obstetrical choices. We described and compared the city-based distribution of all above factors, aiming to explain how anxiety and obstetrical choices existed and differed. Main Outcome Measures: To explore why differences existed, we estimated the impact of the epidemic on women’s anxiety by multivariable analysis. Results: Distribution differences could be seen between cities in employment status, household income, gestational age, fetal number, and exposure history. Women’s attitudes towards COVID-19 in Wuhan were more extreme than that in Chongqing. The anxiety rate was more than double in Wuhan (24.47%) compared to that in Chongqing (10.44%). Generally speaking, obstetrical choices were similar among the 1947 participants, but more obvious in Wuhan. Conclusions: Our study found that the outbreak aggravated prenatal anxiety, and the influence factors could be targets of mental care. Synchronously, vital obstetrical choices changed, followed by pertinent professional advice to prevent irreversible adverse pregnancy outcomes. Online platforms may play crucial roles to address patients’ needs in future PHEs.
