The Association Between Gut Microbiota Diversity and Postpartum Depression: A Prospective Pilot Study

Massachusetts General Hospital·observational·Posted Nov 13, 2025·Updated Jun 8, 2026

In Brief

An observational study for Depression During Pregnancy. Completed, enrolled 30 participants across 1 site.

Detailed Summary

This study aims to examine whether naturally occurring bacteria in the gastrointestinal tract are associated with mood changes following childbirth, including postpartum depression. Biological samples will be collected before and after delivery to determine whether specific patterns in gut bacterial composition are linked to emotional states. The purpose of the research is to improve understanding of whether such microbial changes can help identify individuals at higher risk for postpartum depression, enabling earlier recognition and intervention.

Arms & Interventions

High-Edinburgh Postnatal Depression Scale cohortother

Pregnant participants with antepartum Edinburgh Postnatal Depression Scale (EPDS; range 0-30; higher scores indicate more depressive symptoms) ≥13. Peripheral venous blood (serum) and rectal swab collected ≤3 days pre-delivery and ≤2 days postpartum; optional 6-week follow-up. Observational only-no interventions assigned.

Low-Edinburgh Postnatal Depression Scale cohortother
