Research has shown that maternal mental state is closely correlated with PPD, those undergo the emergency or significant life changes during the postpartum period are more likely to suffer from PPD. In this study, we conducted the meta-analysis to estimate the association between PPD and COVID-19 pandemic. METHODS: PubMed, Web of Science, PsycINFO, ScienceDirect, CNKI, China Science and Technology Journal Database, and WANFANG Database were searched for potentially relevant articles published before April 2022.

The overall pooled prevalence of PPD in the review was 24 % (95 % CI: 0.19–0.29), with China's at 22 % (95 % CI 0.16–0.28) and other countries at 25 % (95 % CI 0.18–0.32) during the COVID-19 pandemic. Moreover, compared to those who did not experience COVID-19, those who experienced it had an increased risk of PPD[OR:1.83(95 % CI 1.70–1.97)]. CONCLUSIONS: According to this analysis, there was a significantly higher prevalence and odds of PPD in those who suffered from the COVID-19 pandemic. Additionally, we also found that China had a lower prevalence of postpartum depression than other countries during the COVID-19 pandemic.
