Emerging Research Highlights Advances in Predicting Postpartum Mental Health Risks

Two recent studies published in the American Journal of Psychiatry during Maternal Mental Health Awareness Month and the 2025 APA Annual Meeting shed new light on predicting postpartum mental health conditions. These investigations focus on identifying women at risk for postpartum depression and psychosis, enhancing early intervention strategies.

The first study evaluated the risk of postpartum depression in women with no prior history of depression. Researchers analyzed data from over 29,000 women across multiple hospitals from 2017 to 2022. They found that approximately 9% of these women experienced postpartum depression within six months postpartum. Using machine learning, the researchers developed a predictive model that accurately identified nearly 30% of women who would develop postpartum depression and correctly recognized 90% of women who would not. This tool has the potential to assist healthcare providers in preemptively identifying high-risk patients before hospital discharge, enabling tailored postpartum care.

The second study examined familial and genetic factors contributing to postpartum psychosis, a rare but severe mental health disorder. By analyzing records of over 1.6 million women from Swedish nationwide registries, the study revealed that women with a sister who had experienced postpartum psychosis are over ten times more likely to develop the condition themselves. The presence of bipolar disorder in a sister doubles this risk, and women with both a sister with bipolar disorder and postpartum psychosis face a 14-fold increased risk. Despite the elevated relative risk, the overall absolute risk remains low at about 1.6%. These findings underscore the importance of family history in postpartum mental health screening and offer insights for clinicians in counseling and risk assessment.

The research presented emphasizes the significance of early identification and personalized care strategies for postpartum mental health conditions. Experts highlighted the importance of these findings through professional commentary, stressing that improved risk prediction is crucial for safeguarding both maternal and infant well-being.

These studies mark a step forward in understanding the biological, familial, and predictive aspects of postpartum mental illnesses, offering hope for earlier interventions and better clinical outcomes.
