TOPLINE:
Postpartum exercise reduces the severity of depressive and anxiety symptoms. Initiating exercise within 12 weeks postpartum is linked to greater reductions in depressive symptoms.
METHODOLOGY:
Researchers conducted a systematic review and meta-analysis including 35 studies with a total of 4072 participants.
The review included randomized controlled trials and nonrandomized interventions examining the impact of postpartum exercise on depression and anxiety.
Participants were postpartum individuals within the first year after childbirth, with interventions including various types of exercise.
Data sources included online databases with data up to January 2024, reference lists, and hand searches.
The Grading of Recommendations, Assessment, Development, and Evaluation framework was used to assess the certainty of evidence.
TAKEAWAY:
Postpartum exercise-only interventions resulted in a moderate reduction in the severity of depressive symptoms (standardized mean difference [SMD], −0.52; 95% CI, −0.80 to −0.24).
Exercise-only interventions were associated with a small reduction in the severity of anxiety symptoms (SMD, −0.25; 95% CI, −0.43 to −0.08).
Initiating exercise within 12 weeks postpartum was associated with a greater reduction in depressive symptoms compared with starting later.
Postpartum exercise was associated with a 45% reduction in the odds of developing depression (odds ratio, 0.55; 95% CI, 0.32-0.95).
IN PRACTICE:
“Further investigation should aim to investigate the effects of postpartum exercise in individuals who experienced perinatal complications and in those who had limitations to exercise during pregnancy. Additionally, more investigation is required to address the possible lasting effects of postpartum exercise on maternal mental health as there were very limited studies reporting on this outcome,” the authors of the study wrote.

LIMITATIONS:
This study’s limitations included high heterogeneity among included studies, small sample sizes in some studies, and the combination of exercise with other interventions in some cases. These factors may have affected the generalizability and precision of the findings.
