Non-Pharmacological Strategies for Postpartum Depression: A Network Meta-Analysis of Randomized Controlled Trials

Objective: Postpartum depression (PPD) has a significant impact on the mother, child and family. Pharmacologic therapy in breastfeeding mothers often causes side effects, so non-pharmacologic alternatives are needed. This study aims to systematically review and synthesize evidence from randomized controlled trials (RCTs) on the effectiveness of non-pharmacological interventions for PPD through a network meta-analysis. Method: This network meta-analysis synthesizes evidence from RCTs evaluating non-pharmacological interventions for PPD. We reviewed 13 articles from PubMed, Science Direct, Scopus, and Cochrane Library. Network Meta-Analysis was performed using RStudio with a random effects model, while Rob 2.0, RoB-ME, and CINeMA were used to assess the risk of bias. Results: The analysis showed that Therapy-Assisted Internet Cognitive Behavioral Therapy (TA-iCBT) had the highest benefit with a Mean Difference (MD) of 6.90 [95% CI 5.35 to 8.45], p = 0.005, as well as the highest effectiveness (P-score 0.891) and very low heterogeneity (I² = 0%). Qualitatively, other alternative therapies are also safe for the mother, but need to be tailored to the patient's needs. Conclusion: In conclusion, TA-iCBT is the most effective non-pharmacological therapy for PPD and can be the main choice in the psychiatric treatment of PPD patients.
