According to the Centers for Disease Control and Prevention, nationwide about one expectant mother out of every nine will experience symptoms of postpartum depression.

But the terminology—baby blues, postpartum depression, and perinatal depression—can be confusing. The difference is in timing and symptoms. The baby blues last a maximum of two weeks after birth, but postpartum depression can last until a child’s first birthday. Perinatal depression encompasses it all—depression during pregnancy and a year after delivery.

For women experiencing postpartum depression, the symptoms far exceed the baby blues in their intensity. These symptoms can include excessive crying, panic attacks, withdrawal from family and friends, and difficulty bonding with the baby.

The impacts can affect both mother and baby. In addition to increasing the risk of suicidal thoughts and suicide, postpartum depression can interfere with a mom’s ability to care for and connect with her newborn. For babies, perinatal depression in the mother has been linked to preterm births; an increased risk for low birth weight, meaning less than 5 pounds, 8 ounces;  and babies smaller in size than is normal for the number of weeks of pregnancy.

In February 2019, the US Preventive Services Task Force recommended women who are pregnant or have recently given birth and have increased risk factors for perinatal depression—including personal or family history of depression, lower socioeconomic status, and adolescent parenthood—receive referrals for counseling.

The task force found that for those patients, interventions, such as cognitive behavioral therapy, can effectively prevent perinatal depression. The group cited one cognitive behavioral therapy program in particular—Mothers and Babies, which Darius Tandon, PhD, is examining in his PCORI-funded study.

His team is assessing whether lay home visitors, who do not have advanced mental health training but often have established relationships with clients, can be as effective at preventing postpartum depression as when mental health professionals lead the program.

“I think this is so important and innovative because home visiting occurs in every state in the United States,” says Tandon, who is the co-director of the Center for Community Health within the Institute for Public Health and Medicine at Northwestern University’s Feinberg School of Medicine. “There are hundreds of home visiting programs that exist with thousands of women in them, giving us the opportunity to intervene and keep women who have some elevated depressive symptoms from worsening.”

A group of 16 stakeholders guided the study. Members included women enrolled in home visiting who received the intervention, home visiting clients who had not, mental health professionals, researchers, home visiting program managers, and a representative from an Illinois government agency overseeing home visiting in the state.

One of the stakeholders was Sara Barrera, a program manager at Advocate Healthcare in Chicago, Illinois, for 16 years, primarily working with postpartum women. Their program serves women of lower socioeconomic status who are age 25 and younger and either pregnant or have recently delivered their baby.

Her team’s experience with referrals for mental health services has shown her the potential benefits of home visitor-led Mothers and Babies groups.

“As home visitors, we were in a position where families were disclosing intense things like struggling with depression, but we had difficulty getting people to actually keep mental health appointments,” Barrera says. “People go where the relationship is and patients already feel safe to talk to home visitors.”

As a stakeholder, she contributed her insights into what has and has not worked for planning Mothers and Babies groups within organizations, and what is fair or a burden to program staff.  

“For places without a mental health clinician or that can’t afford one, home visitor-led Mothers and Babies Programs are an accessible model to implement,” says Barrera, who’s also a trained doula, providing emotional and physical support during the birthing process.

As Summer 2019 draws to a close, so too will the study. While analysis of the results begin, Tandon will speak about the Mothers and Babies Program at the annual conference of Zero to Three, an organization dedicated to ensuring a healthy start to the first three years of life. He will also present a poster at the 2019 PCORI Annual Meeting and the Marcé of North America Biennial Conference on Perinatal Mental Health.

Once findings are available, the team plans to disseminate them to audiences that include experts in perinatal mental health, community mental health centers, early childhood programs, and the home visiting community.   

Barrera, a member of that community, applauds the research team for wanting to continue to partner and share the results with those who, like herself, are already working to help families.

“Now more than ever, it is really valuable to fund maternal health research initiatives that involve home visiting programs,” Barrera says. “By collaborating with groups that are already addressing poverty, mental health issues, and access to care in vulnerable populations, it maximizes the potential for improving maternal health outcomes.”
