Abstract

<p>This study aimed to investigate whether combination of physical performance tests and demographic data can estimate cognitive impairment in early stage. Participants were 486 community-dwelling older adults (73.7 ± 5.2 years, women 54.5%). Grip strength, 5-m habitual walk, and rapid circle drawing task were used as physical performance tests. The trail making test part A, B, and verbal fluency task were administered to use as indicator of early cognitive impairment. A stepwise multiple regression analysis in each gender was performed. Cognitive function tests were entered as dependent variable, and physical performance tests and demographic data (age, education, and body mass index) were entered as independent variables. In men, coefficient of determination in the trail making test part A, B, Δ trail making test (part B minus part A), and verbal fluency task were 0.21, 0.19, 0.10, and 0.18, respectively. In women, coefficient of determination in the trail making test part A, B, Δ trail making test, and verbal fluency task were 0.14, 0.21, 0.14, and 0.09, respectively. Although combination of performance tests and demographic data depended on cognitive function tests, only rapid circle drawing task were selected in all analysis in this study. These results suggest that rapid circle drawing task, which evaluates hand motor function, would be beneficial to grasp early cognitive impairment, and selecting effective combination of physical performance tests and demographic data is required based oncognitive function tests.</p>
