To evaluate both shared and unique risk factors for maintaining physical and cognitive function into the 9th decade and beyond. Longitudinal cohort study. Four US communities. 1677 participants in the Cardiovascular Health Study All Stars Study, assessed in 2005/06. Median age: 85 (range 77-102), 66.5% women, 16.6% black. Intact function was defined as no difficulty with any activities of daily living and a score >=80 on the Modified Mini-Mental Exam. Baseline characteristics assessed in 1992/93 included demographics, behavioral health factors, chronic disease history, subclinical disease markers, cardiovascular risk factors and inflammatory markers. Multinomial logistic regression was used to compare risk for physical disability, cognitive impairment, combined impairments vs. no functional impairment. Of the 1677 participants evaluated in both domains, 891 (53%) were functionally intact. Continuous measures of function, including the Digit Symbol Substitution Test and gait speed showed that all groups, including the most functional, had declined over time. The functional group had less decline, but also tended to have higher starting values. Functional individuals had a very high baseline health profile compared to those with either physical or cognitive impairment or both impairments combined. Women and individuals with higher weight had higher rates of physical impairment but not cognitive impairment. Risk factors common to both types of impairment included cardiovascular disease and hypertension. Intact function was found in only about half of these older adults in the 9th decade and beyond. High baseline function and low vascular disease risk characterized functional aging.
