BACKGROUND: Long-term trajectories of disability comparing decedents and survivors and differences by race have not been assessed.
OBJECTIVE: To examine self-reported difficulty in walking a quarter mile and the need for assistance with activities of daily living (ADL) beginning 3 years before death among decedents and age- and gender-matched survivors.
DESIGN: A case-control sample drawn from the Health, Aging and Body Composition Study (Health ABC). Data were collected between 1997 and 2015.
PARTICIPANTS: Of the 1991 participants who died by the end of the study, 1410 were interviewed for 3 years prior to death, including an interview 6 months before dying. Of these, 1379 decedents were successfully matched by age and gender with 1379 survivors and tracked over the same 3-year period.
MAIN MEASURES: Self-reported difficulty walking a quarter mile and the ability to perform activities of daily living without assistance (bathing, dressing, transferring).
KEY RESULTS: Decedents (mean age at death, 84) increased in mobility disability from 44.1% 3 years before death to 69.4% 6 months before death and in ADL disability from 32.9% to 58.4%. Among survivors, mobility disability increased from 31.4% to 40.7% and ADL disability from 17.4% to 31.4%. The proportion of decedents and survivors with mobility disability differed significantly in adjusted models at all assessment points (p < 0.0001). African-American survivors were significantly more disabled than White survivors at all points (p < 0.0001), but trajectories of disability among decedents did not differ by race in the last 18 months of life (p = 0.35).
CONCLUSIONS: Trajectories of self-reported disability differ between survivors and decedents. Older adults who died were more disabled 3 years before death and also had a greater risk of increasing disability over each subsequent 6-month assessment. The gap in disability between African Americans and Whites was erased in the final 1 to 1.5 years before death.
