Antenatal psychological interventions may ameliorate postpartum depression: a systematic review and meta-analysis

Psychological interventions during pregnancy can significantly reduce postpartum depression-related scale scores and incidence rates, and improve depressive symptoms, anxiety, and perceived stress. However, due to the heterogeneity of intervention types, this study cannot determine the optimal intervention method and thus provides preliminary evidence for clinical prevention. Clinicians should select interventions based on resource availability and individual characteristics of pregnant women, while future studies should focus on direct comparisons of different intervention types to provide more targeted guidance.
