Study Characteristics

Study Participants From June 1, 1990 through August 31, 1991, the study enrolled primarily African American women at fewer than 29 weeks of gestation, with no previous live births, and with at least 2 of the following sociodemographic risk characteristics: unmarried, fewer than 12 years of education, and unemployed. Of the 1,290 eligible women, 1,139 consented and were randomly assigned. A subset of 743 women were involved in the postnatal aspect of the trial. Of the women enrolled, 92.1% were African American, 98.1% were unmarried, 64.1% were 18 years or younger at registration, and 85.1% came from households with annual incomes below the U.S. federal poverty guidelines. This study focused on the 12-year follow up; 594 women completed a maternal interview and 578 children completed an interview.
Setting Memphis, TN
Home Visiting Services Women in the nurse-visited group were provided the same services as those in the comparison group, plus home visitation from pregnancy through the child’s second birthday. The nurses were provided detailed guidelines for each visit but allowed to adapt them to the needs of individual families. The nurses also linked families to other health and human services and tried to involve the children’s fathers and grandmothers in the pregnancy and care of the child. Each nurse visited a maximum of 25 families.

The program is intended to provide 62 home visits for women who enroll at 16 weeks gestation. In this study, the nurses completed a mean of 7 home visits (range of 0 to 18) during pregnancy and 26 home visits (range of 0 to 71) during the first 2 years after birth. Generally the difference between the recommended and actual number of visits was the result of participants dropping out of the program.

Comparison Condition Women in the comparison group were provided developmental screening and referrals for the child at 6, 12, and 24 months of age, and free transportation for scheduled prenatal care.
Staff Characteristics and Training All home visitors were nurses. No other information on training is provided.
