Summary
Peer support effectively prevents and treats perinatal depression. This meta-analysis found interventions delivered during pregnancy or postpartum, via various methods and frequencies, significantly improved maternal mental health.
Area of Science:
- Perinatal Mental Health
- Psychiatry
- Public Health
Background:
- Perinatal depression is a significant global health concern.
- Effective interventions are crucial for maternal well-being.
- Peer support has emerged as a promising intervention strategy.
Purpose of the Study:
- To systematically evaluate the efficacy of peer support in preventing and treating perinatal depression.
- To synthesize findings from randomized controlled trials (RCTs) through meta-analysis.
Main Methods:
- Systematic search of eight major databases for RCTs up to July 2021.
- Independent critical appraisal of bias and data extraction by two reviewers.
- Meta-analysis of 16 studies involving 3154 participants.
Main Results:
- Peer support significantly reduced perinatal depression compared to control groups (SMD = -0.39).
- Interventions were effective whether delivered during the perinatal or solely postpartum periods.
- Both face-to-face and remote (telephone/internet) interventions showed significant benefits.
- Combined individual and group sessions, and weekly interventions, demonstrated the strongest positive effects.
- Peer support proved effective across low-, middle-, and high-income countries.
Conclusions:
- Peer support is a viable and effective strategy for managing perinatal depression.
- Flexible delivery models, including remote and combined approaches, are recommended.
- Regular and consistent peer support, particularly weekly, enhances effectiveness.

01:52Regression Toward the Mean
6.5K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
