Examining the impact of Medicaid payments for immediate postpartum long-acting reversible contraception on the mental health of low-income mothers.

Objective: To examine the effect of Medicaid immediate postpartum long-acting reversible contraception (IPP LARC) reforms on self-reported mental health among low-income mothers aged 18-44 years.

Data Sources And Study Setting: We used national secondary data on self-reported mental health status in the past 30 days from the core component (2014-2019) of the Behavioral Risk Factor Surveillance System (BRFSS).

Study Design: We estimated linear probability models for reporting any days of not good mental health in the past 30 days. We adjusted for individual-level factors, state-level factors, and state and year fixed effects. Our primary independent variable was an indicator for IPP LARC payment reform. We examined the effect of the Medicaid payment reforms on self-reported mental health status in the past 30 days using difference-in-differences and event-study designs.

Data Collection/extraction Methods: Not applicable.

Principal Findings: State adoption of Medicaid IPP LARC reforms was associated with significant reductions (between 5.7% and 11.5%) in the predicted probability of reporting any days of not good mental health among low-income mothers. Treatment effects appeared to be driven by respondents reporting two or more children (less than 18 years of age) in the household (ATT = -0.028, p = 0.04). Results are robust to a series of sensitivity tests and alternative estimation strategies.

Conclusions: Our findings suggest that contemporary efforts to improve access to contraceptive methods may have important benefits beyond reproductive autonomy. These findings have implications for policymakers as the landscape related to family planning services continues to shift.
