Comparing the Effectiveness of Antidepressants and Cognitive Behavioural Therapy in Preventing Postnatal Depression:...

Postnatal depression (PND) is a prevalent depressive disorder frequently accompanied by anxiety, with significant implications for maternal health and infant development. This systematic review compared the effectiveness of antidepressant medications and cognitive behavioural therapy (CBT) in the treatment of PND. A systematic search of PubMed and Medline was conducted on November 20, 2019, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and randomized controlled trials (RCTs) published between 1997 and 2019 were included. Four RCTs (N = 421) conducted in the UK, USA and Australia met the eligibility criteria. At four weeks, women treated with selective serotonin reuptake inhibitors (SSRIs) demonstrated significantly greater reductions in anxiety symptoms compared to those receiving CBT (95% confidence interval (CI): 1.8-6.5; p < 0.001), with sustained improvement at 18 weeks (95% CI: -3.3 to -0.9; p < 0.001). Conversely, CBT was associated with a faster decline in anxiety symptoms after 12 weeks (p = 0.009). Both interventions achieved significant overall clinical improvements (p < 0.01), while combined therapy did not confer additional benefits beyond monotherapy. These findings suggest that SSRIs may provide superior short-term and sustained relief of anxiety symptoms, whereas CBT may support longer-term symptom control. Therefore, treatment selection should consider symptom severity, potential side effects, breastfeeding and patient preferences.
