What were the study results?

During the first five years following childbirth, one out of every five mothers who gave birth to a preterm baby had symptoms of depression, while one out of every ten mothers who gave birth to a full-term baby had symptoms of depression. For mothers of preterm infants, it was also more common to have symptoms that got worse over time compared to women who gave birth to full-term babies. The most severe symptoms of depression were seen in women who gave birth early.

What was the study's impact?

This study supports previous reports that many mothers struggle with their mental health after giving birth, and women who have preterm babies may be particularly at risk for symptoms of depression—such as sadness, stress, anxiety, and feelings of being overwhelmed. Maternal mental health can influence their child’s health and development. Right now, doctors only screen women for depression symptoms when they are pregnant and for six months after they have their babies. This study shows that some women continue to struggle with depression for years after they give birth or start experiencing depression when their children are older. This trend was especially true for women whose babies were born prematurely. This study shows the importance of asking women about their mental health for much longer than six months after they give birth and helping them find supportive interventions.

Why was this study needed?

The postpartum period can be especially hard for mothers when babies are born prematurely, but researchers don’t know much about the effect that preterm births can have on a mother’s mental health. This study assessed postpartum depressive symptom trajectories for mothers of preterm and full-term babies, and followed participating mothers for five years after birth to better understand the long-term risks for depression and potential opportunities for treatment.

Who was involved?

The study involved 11,320 pregnant women aged 18 to 52 years old from 35 ECHO cohorts across the United States. About 11% of these women had babies that were born before they were due (preterm infants) and 89% had babies that were born on or near their due date (full-term infants).

What happened during the study?

Researchers analyzed self-reported depression measurements for women when they were pregnant and after they had their babies. These women also completed at least one follow-up assessment before their children were 5 years old.

What happens next?

It is important for future research to study what factors put some women at higher risk of experiencing depression after giving birth, particularly mothers of premature babies. Future research should also investigate what types of programs can help support mothers and their mental health during pregnancy and after birth.
