| Study participants | The study population included 126,880 women who were recipients of Medicaid and delivered a baby during the 2009-2012 calendar years in Michigan, with 63,440 women each in the treatment and comparison groups. The study sample was, on average, 24.5 years old. Twenty-six percent of the women were married. About 57 percent of women in the research sample were white, 36 percent were black, less than 1 percent were American Indian, and 6 percent were another race or ethnicity. More than 26 percent of women in the research sample were living at less than 33 percent of the federal poverty level, and 55 percent were receiving Medicaid before their pregnancy. |
|---|---|
| Setting | The study took place throughout the state of Michigan. |
| Intervention services | MIHP provides prenatal and postnatal home visiting to pregnant women and infants living in Michigan who are Medicaid beneficiaries. Participation is voluntary, and includes health risk screenings, care coordination, referrals to other services, and interventions that are tailored to the needs of each person. These interventions may address healthy pregnancies, positive birth outcomes, infant safety, and infant health and development. |
| Comparison conditions | Women in the comparison condition received Medicaid during the study period but did not volunteer to participate in any MIHP services. |

Full sample; Michigan Medicaid 2009-2012 birth cohort | One year following birth | 126,880 infants | Unadjusted proportion = 0.01 | Unadjusted proportion = 0.01 | OR = 0.73 | HomVEE calculated = -0.19 | Statistically significant, p < 0.01 | Negative effect is favorable to the intervention. Program and comparison group proportions are less than 0.010. HomVEE calculated the effect size based on the study-reported odds ratio. |
