Abstract

Objective: To compare the prevalence of postpartum depression (PPD) symptoms between high-income countries (HIC) and low-and middle-income countries (LMIC) during the COVID-19 pandemic. Methods: The PubMed, Embase, Virtual Health Library, Scopus, Web of Science, PsycINFO, and CINAHL databases were searched until October 2022 for studies that collected data during the pandemic. The metaprop command was used in the Stata statistical software version 12.0 to run a random-effects meta-analysis. Results: A total of 15 studies with 4,788 postpartum women were included. The overall prevalence of PPD symptoms was 31% (95%CI 21.85-40.99). The pooled prevalence of PPD symptoms among women from HIC (30.5% [95%CI 16.95-46.02]) did not differ significantly from that of women from LMIC (31.5% [95%CI 19.26-45.15]). However, studies that analyzed women up to 1 month after childbirth reported a lower prevalence of PPD symptoms (17.5% [95%CI 9.85-26.62]) compared to those that observed them up to 1 year after childbirth (38.3% [95%CI 33.96-42.83]). Conclusions: The prevalence of PPD symptoms was high across countries, regardless of human development index. This condition must be regularly tracked worldwide to assess, discuss, and recommend more assertive steps that may be implemented to address it based on the particular characteristics of each country.
