Global prevalence of perinatal depression and anxiety during the COVID-19 pandemic: An umbrella review and meta-analytic synthesis.

During the COVID-19 pandemic, depression and anxiety were common, affecting almost one in three perinatal women globally. A high heterogeneity and a risk of publication bias were found, partially due to the variety of assessment tools and cut-offs. The results may not be generalized to minorities. Studies on the prevalence of clinical diagnoses are needed. Based on our results it is not possible to firmly affirm that the COVID-19 pandemic was the main factor that directly increased perinatal depression and anxiety during the past few years. Future studies should study other factors' impact.
