Health insurance remains an important dimension of contraceptive access. This study investigated the role of insurance in contraceptive use, access, and quality in South Carolina and Alabama. The study used a cross-sectional statewide representative survey that assessed reproductive health experiences and contraceptive use among reproductive-age women in South Carolina and Alabama. The primary outcomes were current contraceptive method use, barriers to access (inability to afford wanted method, delay/trouble obtaining wanted method), receipt of any contraceptive care in the past 12 months, and perceived quality of care. The independent variable was insurance type. Generalized linear models were applied to estimate prevalence ratios for each outcome's association with insurance type while adjusting for potentially confounding variables. Nearly 1 in 5 women (17.6%) was uninsured, and 1 in 4 women (25.3%) reported not using a contraceptive method at the time of the survey. Compared with women with private insurance, women with no insurance had a lower likelihood of current method use (adjusted prevalence ratio 0.75; 95% confidence interval 0.60-0.92) and receipt of contraceptive care in the past 12 months (adjusted prevalence ratio 0.61; 95% confidence interval 0.45-0.82). These women also were more likely to experience cost barriers to access care. The insurance type was not significantly associated with the interpersonal quality of contraceptive care. Findings highlight the need for expanding Medicaid in states that did not do so under the Patient Protection and Affordable Care Act, interventions to increase the number of providers who accept Medicaid patients, and protections to Title X funding as key elements for enhancing contraceptive access and population health outcomes.
