Background: Disability in activities of daily living (ADLs) is a dynamic process and transitions among different disability states are common. However, little is known about factors affecting recovery from disability. We examined the association between frailty and recovery from disability among non-disabled community-dwelling elders.

Methods: We studied 1023 adults from the Cardiovascular Health Study (CHS) and 685 adults from the Health and Retirement Study (HRS), who were ≥65 years and had incident disability, defined as having difficulty in ≥1 ADL (dressing, eating, toileting, bathing, transferring, walking across a room). Disability recovery was defined as having no difficulty in any ADLs. Frailty was assessed by slowness, weakness, exhaustion, inactivity, and shrinking. Persons were classified as "non-frail" (0 criteria), "prefrail" (1-2 criteria), or "frail" (3-5 criteria).

Results: In total, 539 (52.7%) CHS participants recovered from disability within one year. Almost two-thirds of non-frail persons recovered, while less than two-fifths of the frail recovered. In the HRS, 234 (34.2%) participants recovered from disability within two years. Approximately half of the non-frail recovered, while less than one-fifth of the frail recovered. After adjustment, prefrail and frail CHS participants were 16% and 36% less likely to recover than the non-frail, respectively. In the HRS, frail persons had a 41% lower likelihood of recovery than the non-frail.

Conclusions: Frailty is an independent predictor of poor recovery from disability among non-disabled older adults. These findings validate frailty as a marker of decreased resilience and may offer opportunities for individualized interventions and geriatric care based on frailty assessment.
