Notes from the review of this manuscript
In 2020, HomVEE updated this review to move 18 findings related to child injuries and ingestions that were mistakenly placed in the Child Health domain to the Reductions in Child Maltreatment domain where HomVEE typically categorizes such findings.

This study included participants from the following locations:
- Michigan
Study Participants
The study population included 27,320 women (13,660 women each in the treatment and comparison groups) who were recipients of Medicaid, delivered a baby during the 2011 calendar year in Michigan, and for whom the baby survived his or her first year after birth. The study sample was, on average, 25 years old. Slightly less than 27 percent of the women were married. About 57 percent of women in the research sample were white, 37 percent were black, 5 percent were a different race or ethnicity, and less than 1 percent were American Indian. Just more than one-quarter of women in the research sample were living at or below 33 percent of the federal poverty level, and about two-thirds were receiving Medicaid before their pregnancy.
Setting
The study took place across the state of Michigan.
Intervention condition
Note: Navigate to the model page for more information about the home visiting model. See the source manuscript for more information about how the model was implemented in this study.
Comparison Conditions
People in the comparison condition received Medicaid during the study period but did not participate in any MIHP services.
Funding Sources
The study was partly supported through a grant from the Michigan Department of Community Health.
