In a study funded by the National Institutes of Health, researchers examined how expansions for state Medicaid for American Indian/Alaska Native (AI/AN) women were associated with health insurance, prenatal care, health conditions, and birth outcomes. They found Medicaid expansions increased the proportion of AI/AN women reporting healthcare coverage, had no effects on the first-trimester prenatal care usage or birthweight of AI/AN women, and mixed evidence of increased rates of pre-pregnancy chronic conditions after expansions.
