| Annotation | The relationship between cognitive function and physical disability in non-demented older people is not well characterised. The hypothesis was tested that poor performance on tests of cognitive processing speed would be associated with poor physical performance. Participants in this study were 125 men and women aged 75 and over who did not engage in regular exercise and were enrolled in intervention trials of exercise or hormone replacement therapy (HRT). measures obtained included Trail-Making A and B tests, Cancellation Random Figures test, Wechsler Associate Learning and 20-minute Delayed Recall, Verbal Fluency test, a modified Physical Performance Test (PPT), and self-reports about performance of activities of daily living (ADLs), medication use, and hospitalisation in the previous year. A factor analysis of the psychometric test battery demonstrated that two factors - a cognitive speed factor, and a memory factor - accounted for 55% of the variance in cognitive test performance. Hierarchical multiple regression analyses demonstrated that age, number of medications, and the cognitive speed factor were independent predictors of total modified PPT score. (RH). |
