Background: This study examined the association between Medicaid expansions under the Affordable Care Act (ACA) and births among low-income women of reproductive age in the United States. Materials and Methods: We used data from the 2008 to 2019 American Community Survey to estimate the association between state adoption of Medicaid expansion under the ACA and the percent of low-income women of reproductive age with a birth in the past year using a difference-in-difference research design. Subgroup analysis was explored by race and ethnicity, age group, educational attainment, marital status, and number of children. Results: We found that Medicaid expansion was associated with a small reduction in births among low-income women of reproductive age by 0.45 percentage points (95% confidence interval: −0.84 to −0.05). In subgroup analyses, we found reductions in births among Hispanic women, American Indian or Alaska Native women, women 25–29 years of age, women 35–39 years of age, unmarried women, and women with more than three children. Conclusions: Reductions in births associated with Medicaid expansion could suggest that expanding Medicaid addressed previously unmet reproductive health care needs among low-income women of reproductive age. The reductions in births among low-income women that we observe were occurring among some groups with higher unintended pregnancy rates, including Hispanic women, American Indian or Alaska Native women, young women, and unmarried women. These findings underscore the importance of reproductive health care access through insurance coverage on empowering women to have control over their reproductive decision-making and timing.

We examined the impact of California's early Medicaid expansion under the Affordable Care Act on the use of payday loans, a form of high-interest borrowing used by low- and middle-income Americans. Using a data set for the period 2009-13 (roughly twenty-four months before and twenty-four months after the 2011-12 Medicaid expansion) that covered the universe of payday loans from five large payday lenders with locations around the United states, we used a difference-in-differences research design to assess the effect of the expansion on payday borrowing, comparing trends in early-expansion counties in California to those in counties nationwide that did not expand early. The early Medicaid expansion was associated with an 11 percent reduction in the number of loans taken out each month. It also reduced the number of unique borrowers each month and the amount of payday loan debt. We were unable to determine precisely how and for whom the expansion reduced payday borrowing, since to our knowledge, no data exist that directly link payday lending to insurance status. Nonetheless, our results suggest that Medicaid reduced the demand for high-interest loans and improved the financial health of American families. [ABSTRACT FROM AUTHOR]
