Recent research suggests conflicting secular trends in the health of the older obese population, with some health indicators improving and others declining. Little research has examined how obesity-related health care spending has changed over time. Using data from the Medicare Current Beneficiary Surveys conducted from 1997-2006, we examine whether time trends in Medicare and prescription drug expenditures differ for overweight and obese beneficiaries relative to normal weight beneficiaries. We find that Medicare Part A & B expenditures have increased for all weight groups over time, but expenditures increased significantly faster for overweight and obese beneficiaries. Increases in the prevalence of weight-related chronic conditions appear to account for this trend.
