Background:
Up to 20% of women experience postpartum depression (PPD). PPD is associated with anxiety and poor health-related quality of life (HRQOL). Efficacious treatments are critical; many women with PPD prefer complementary therapies. Thus, the current study examined yoga as a complementary therapy for PPD.
Methods:
Fifty-seven postpartum women with scores ≥12 on the Hamilton Depression Rating Scale were randomly assigned to a yoga (N = 28) or wait-list control (N = 29) group. The yoga intervention consisted of 16 classes over 8 weeks. Outcomes were depression, anxiety, and HRQOL.
Results:
The yoga group experienced significantly greater rate of improvement in depression, anxiety, and HRQOL, relative to the control group with moderate to large effects. Reliable Change Index analyses revealed that 78% of women in the yoga group experienced clinically significant change.
Conclusion:
These findings support yoga as a promising complementary therapy for PPD, and warrant large-scale replication studies.
