Changes in the Hierarchy of Functional Impairment From Middle Age to Older Age.

ABSTRACT:

Background

Understanding the hierarchy of functional impairment in older adults has helped illuminate mechanisms of impairment and inform interventions, but little is known about whether hierarchies vary by age. We compared the pattern of new-onset impairments in activities of daily living (ADLs) and instrumental ADLs (IADLs) from middle age through older age.

Methods

We conducted a cohort study using nationally representative data from 32 486 individuals enrolled in the Health and Retirement Study. The outcomes were new-onset impairment in each ADL and IADL, defined as self-reported difficulty performing each task, assessed yearly for 9 years. We used multistate models and competing risks survival analysis to estimate the cumulative incidence of impairment in each task by a
