footnote376

Outcome ratings vary by comparison and whether the outcome was assessable at baseline. Comparisons with low attrition rate high if the outcomes were not assessable at baseline or if measures of the outcomes were equivalent at baseline. Comparisons with low attrition rate moderate if measures of the outcomes were assessable at baseline but equivalence was not demonstrated. Comparisons with high attrition rate moderate if measures of the outcomes were not assessable at baseline and low if they were assessable at baseline but equivalence was not demonstrated. Information on baseline equivalence for race and ethnicity and socioeconomic status was based on correspondence with the author.

Study characteristics
Study participants	Pregnant Hispanic women older than 18 were recruited to participate in the study and then randomly assigned to MIHOW (94 women) or the comparison condition (94 women). At enrollment, participants were 29.6 years old, on average, and predominantly from Mexico (64.9 percent). Ten percent were employed full-time and an additional 16.5 percent were employed part-time. Fifty-six percent of participants had never been married.
Setting	The study was conducted in the urban Davidson County, Tennessee.
Intervention services	Trained outreach workers conducted monthly home visits until children reached six months. Home visits lasted about one hour and consisted of parenting support, education, and linkages to medical and social services. MIHOW also provided participants with the opportunity to participate in social and educational groups. Participants received printed materials about maternal and child health and development.
Comparison conditions	The minimal intervention group received printed materials about maternal and child health and development at the 35th week of pregnancy and 2 weeks, 2 months, and 6 months postpartum.
Subgroups examined	This field lists subgroups examined in the manuscript (even if they were not replicated in other samples and not reported on the summary page for this model’s report). Subgroups are not listed for manuscripts reviewed before 2021.
Staff characteristics and training	Health outreach workers were community members who completed 40 hours of training, shadowed an experienced outreach worker, and received feedback from a supervisor. Outreach workers also received monthly in-service trainings and attended both regional trainings and an annual conference.
Funding sources	The evaluation was funded through the Affordable Care Act Maternal, Infant, and Early Childhood Home Visiting Program D89MC23542.
Author affiliation	The authors are affiliated with the Vanderbilt School of Nursing, which developed the MIHOW model and partnered in implementation.
Peer reviewed	Peer reviewed status is not listed for manuscripts reviewed before 2021.

Study Registration:

Clinicaltrials.gov Identifier: None found. Study registration was assessed by HomVEE beginning with the 2014 review.
