The COVID-19 pandemic and the experience of postpartum depression

Background: Early studies assessing peripartum mood disorders during the COVID-19 pandemic have conflicting results.Objective: The primary aim was to examine if postpartum depression (PPD) was more common or more severe during the COVID-19 pandemic compared to earlier periods, and to assess what individual factors may worsen the impact of the pandemic.Methods: Electronic health records at an academic pediatric practice in Michigan identified 242 biological mother-child dyads with delivery between 1/1/2017 and 12/31/2021. PPD was evaluated using the Edinburgh Postnatal Depression Scale (EPDS) during well-child visits. Participants were divided into three groups for analysis: Pre-Pandemic (n = 100), Early Pandemic (n = 93), and Later Pandemic (n = 49). Logistic regression analysis was used to predict PPD development, controlling for background factors.Results: After controlling for confounders, the three groups did not differ significantly. Preexisting mental health conditions was a significant (p<.001) moderator; PPD rates peaked early in the pandemic (60%), compared to late pandemic (42%) and pre-pandemic (36%). Women without a mental health diagnosis pre-pregnancy experienced the lowest levels of PPD during the pandemic.Conclusions: Rates of PPD were not significantly affected by the COVID-19 pandemic for most women. However, biological mothers with preexisting mental health conditions had significantly higher rates of PPD.
