Notes from the review of this manuscript

Several findings receive a moderate rating because they have high attrition but establish baseline equivalence. Findings on some outcomes—including Edinburgh Postnatal Depression Scale (EPDS) scores at 2, 6, 12, and 15 months postpartum—receive a low rating because attrition is high, and baseline equivalence is not established. Measures of social and emotional support receive a low rating due to insufficient reliability. Information on baseline equivalence, measures of findings at specific time points, reliability of measures, and other details about the study is based on correspondence with the authors. One outcome, "prior breastfeeding", is not a post-intervention outcome, and therefore was ineligible for review.

This study included participants from the following locations:

  • Tennessee
Study Participants

Research staff visited community businesses and agencies to recruit pregnant Hispanic women for the study. There were also referrals from other study participants through word of mouth. Participants were randomly assigned to the Maternal Infant Health Outreach Worker (MIHOW) intervention (66 women) or the comparison group (66 women). The average age was 30, and the highest percentage of participants were from Mexico (49 percent). When the study began, 8 percent were employed full time, and 12 percent were employed part time. Most (66 percent) did not have a high school diploma, and more than half (53 percent) had never been married.

Setting

The study took place in six counties in central Tennessee.

Comparison Conditions

Pregnant women assigned to the comparison group were given educational materials about maternal and child health and development during the 35th week of pregnancy and when the infant was 2 weeks, 2 months, and 6 months old. These materials were also provided to the intervention group.

Subgroups examined

• Mothers with children at baseline

Author Affiliation

The authors are affiliated with the Vanderbilt School of Nursing, which developed the MIHOW intervention and supports its implementation.
