Interventions to reduce postpartum depression have mainly been focused on enhancing screening to increase treatment rates among women.
1 However, their effectiveness in low- and middle-income countries with limited access to mental health services and treatment resources is currently unknown.
1,2 Preventive strategies are timely from a population health perspective.
2-4 Current evidence supports the use of exercise interventions in the management of maternal depressive symptoms during the perinatal period.
5-7 Encouraging findings on the effectiveness of exercise in reducing antenatal depression have been found in a systematic review and meta-analysis of randomized clinical trials (RCTs).
7,8 Because antenatal depression is an important predictor of postpartum depression,
9 it has been suggested that antenatal physical activity may be a promising approach to preventing postpartum depression.
10 However, most studies on this topic to date are observational, and further RCTs are needed to confirm the findings. The aim of this study was to assess the efficacy of a 16-week exercise intervention during pregnancy on the prevention of postpartum depression using data from a large RCT.
