Objectives. We examined preventive care use by nonelderly adults (aged 18–64 years) before the Affordable Care Act (ACA) and considered the contributions of insurance coverage and other factors to service use patterns. Methods. We used data from the 2005–2010 Medical Expenditure Panel Survey to measure the receipt of 8 recommended preventive services. We examined gaps in receipt of services for adults with incomes below 400% of the federal poverty level compared with higher incomes. We then used a regression-based decomposition analysis to consider factors that explain the gaps in service use by income. Results. There were large income-related disparities in preventive care receipt for nonelderly adults. Differences in insurance coverage explain 25% to 40% of the disparities in preventive service use by income, but education, age, and health status are also important drivers. Conclusions. Expanding coverage to lower-income adults through the ACA is expected to increase their preventive care use. However, the importance of education, age, and health status in explaining income-related gaps in service use indicates that the ACA cannot address all barriers to preventive care and additional interventions may be necessary.
