Abstract

Objectives: To ascertain whether older adults with extensive disease but relative vigor (adapters) shorten the period at the end of life in which they live with morbidity (compress morbidity). Design: Prospective, community-based cohort study in four U.S. cities. Setting: Cardiovascular Health Study. Participants: Individuals aged 65 and older. Measurements: Participants were categorized into three groups according to extent of disease (assessed noninvasively), vigor, and frailty (expected agers (n = 3,528, extent of disease similar to vigor and frailty—reference group), adapters (n = 882, higher disease but vigorous), and prematurely frail (n = 855, lower disease but frail)) and compared according to years of able life (YAL), years of self-reported healthy life (YHL), and mortality using multivariable regression and survival analysis. Results: After adjustment, adapters had 0.97 (95% confidence interval (CI) = 0.60–1.33) more YAL and 0.54 (95% CI = 0.19–0.90) more YHL than expected agers, and those who were prematurely frail had −0.99 (95% CI = −1.36 to −0.62) fewer YAL and −0.53 (95% CI = −0.89 to −0.17) fewer YHL than expected agers. Adapters had 0.9 more and prematurely frail had 1.5 fewer years of total life than expected agers (P
