Disability was defined as having a limitation for at least one of 14 activities of daily living. Physical function was measured using 14 questions across three domains (upper body, lower body, and dexterity) and five performance-based tests (gait speed, timed up and go, single leg stance, chair rise, and grip strength). Logistic regression was used to assess the relationship between physical function operationalized as (i) at least one limitation, (ii) presence or absence of limitations in each individual domain\/test, and (iii) number of domains\/tests with limitations, with disability.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>In the 21,241 participants with self-reported function data, the odds of disability were 1.87 (95% CI: 1.56\u20132.24), 6.78 (5.68\u20138.08), and 14.43 (11.50\u201318.1) for one, two, and three limited domains, respectively. In the 30,097 participants with performance-based measures of function, the odds of disability ranged from 1.53 (1.33\u20131.76) for one test limited to 14.91 (11.56\u201319.26) for all five tests limited.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Both performance-based and self-report measures of physical function were associated with disability.
