However, less is known about their association with adult health care utilization and expenditures.

Objectives: Using data from the nationally representative Medical Expenditures Panel Survey (MEPS), we explored the extent to which health care utilization and health risk-taking, together with previously examined mediators, can explain the education-health gradient above and beyond what can be explained by previously examined mediators such as age, race, and poverty status.

Method: Health was measured using the Physical Component Score (PCS) from the Medical Outcomes Study 12-Item Short Form (SF-12). Educational attainment was self-reported and categorized as 1 (less than high school), 2 (high school graduate or GED), 3 (some college), 4 (bachelor's degree), and 5 (graduate degree).
