Health disparities are differences in health outcomes and access to care among different population groups. The ACA aims to reduce these disparities by expanding Medicaid, providing subsidies for low-income individuals, and prohibiting insurance companies from denying coverage based on pre-existing conditions. These measures help to ensure that underserved and vulnerable populations have better access to health care services. Epidemiologists can use data from these populations to study the impact of social determinants of health and develop targeted interventions to address disparities.
