Effect of Prenatal and Infancy Home Visitation by Nurses on Pregnancy Outcomes, Childhood Injuries, and Repeated Childbearing

Abstract

Context. —Interest in home-visitation services as a way of improving maternal and child outcomes has grown out of the favorable results of a trial in semirural New York. The findings have not been replicated in other populations. Objective. —To test the effect of prenatal and infancy home visits by nurses on pregnancy-induced hypertension, preterm delivery, and low birth weight; on children's injuries, immunizations, mental development, and behavioral problems; and on maternal life course. Design. —Randomized controlled trial. Setting. —Public system of obstetric care in Memphis, Tenn. Participants. —A total of 1139 primarily African-American women at less than 29 weeks' gestation, with no previous live births, and with at least 2 sociodemographic risk characteristics (unmarried, P=.009). During the first 2 years after delivery, women visited by nurses during pregnancy and the first 2 years of the child's life had fewer health care encounters for children in which injuries or ingestions were detected (0.43 vs 0.55;P=.05); days that children were hospitalized with injuries or ingestions (0.03 vs 0.16;P<.001); and second pregnancies (36% vs 47%;P=.006). There were no program effects on preterm delivery or low birth weight; children's immunization rates, mental development, or behavioral problems; or mothers' education and employment. Conclusion. —This program of home visitation by nurses can reduce pregnancyinduced hypertension, childhood injuries, and subsequent pregnancies among low-income women with no previous live births.
