South African 'mentor mothers' improve perinatal health outcomes

But a new study conducted by UCLA's Mary Jane Rotheram-Borus, the director of the UCLA Global Center for Children and Families at the Semel Institute for Neuroscience and Human Behavior, and her colleagues from Stellenbosch University in South Africa found that community-based interventions could improve the health of children in those contexts. A paper about the randomized controlled trial appears in the current edition of the journal PLoS One.

The study found that regular home visits of pregnant mothers, and later of those mothers and their infants, by specially trained lay community mothers from the "Mentor Mothers" program led to significantly better health outcomes 18 months later in both the mothers and their children.

The Mentor Mother home visiting program, developed by South Africa's Philani Maternal, Child Health and Nutrition Project, has been in existence for the past 15 years. Mentor mothers are trained to provide health information and health intervention (such as a home visit), support mothers to improve healthy births, and to help mothers develop coping mechanisms that enable them to raise healthier children. The program currently operates at eight clinic sites in Cape Town and out of Zithulele Hospital, located in a deeply rural part of the country's Eastern Cape region.

Among other outcomes, the study found that Mentor Mother home visits led to a 50 percent improvement by mothers in completing tasks designed to prevent mother-to-child transmission of the HIV virus, compared to mothers in the control group of the study who did not receive home visits, just clinic-based pre- and postnatal care. The virus-transmission prevention tasks included pregnant mothers knowing their own HIV status and asking their sexual partners to be tested; mothers taking anti-retroviral drugs for the six weeks prior to childbirth and during labor; babies receiving anti-retroviral drugs for at least six weeks, until they can be tested for the virus; and mothers using one feeding method (breastfeeding or formula) for the first 6 months of their infants' life, and, when possible, exclusively breastfeeding.

In addition, the study found that mothers who received regular home visits breastfed longer and, among HIV-infected mothers, were more likely to breastfeed exclusively for six months.

"There also tended to be fewer low birth weight babies, a condition which results in life-long problems," said Rotheram-Borus, the Bat-Yaacov Professor of Child Psychiatry and Biobehavioral Sciences and the director of the Center for HIV Identification Prevention and Treatment Services at UCLA.

Furthermore, those mothers who were visited often were more likely to use condoms with sexual partners and were the least likely to have a low birth weight infant; the children from frequently visited homes were less likely to be stunted or malnourished in the first 18 months than were the children of mothers who did not receive in-home peer counseling and support.

In addition, Rotheram-Borus, who was the study's first author, and colleagues found that having mentor mothers visit reduced alcohol use by mothers during pregnancy, based on self-reports by the mothers. Indeed, she said, "at 18 months of age, 65 percent of children who showed signs of fetal alcohol spectrum were in the control group of mothers not receiving the home visits."

Rotheram-Borus and her colleagues are currently following the children to examine which benefits persist at 3 and 5 years of age. "The study's results will tell us how the Philani Programme modifies its outreach efforts as it begins to be globally diffused by the Church of Sweden -- first to Swaziland and Ethiopia, and then throughout Africa."
