Background and Purpose - Functional capacity is a predictor, as well as a consequence, of stroke. However, little research has been done to examine whether higher-level functional capacity above basic activities of daily living is a predictor of stroke. Methods.We followed 1493 Japanese community-dwelling adults aged ≥ 60 years (mean age, 70.1 years) who were independent in basic activities of daily living and had no history of stroke. Baseline data were collected using a selfadministered questionnaire. Higher-level functional capacity was measured using the total score and 3 subscales (instrumental activities of daily living, intellectual activity, and social role) derived from the Tokyo Metropolitan Institute of Gerontology Index of Competence. Adjusted hazard ratios and 95% confidence intervals were calculated by the Cox proportional hazards model. Results.During a mean follow-up of 10.4 years, 191 participants developed a first stroke. Impaired higher-level functional capacity based on total score of the Tokyo Metropolitan Institute of Gerontology Index of Competence was significantly associated with stroke (hazard ratio, 1.64; 95% confidence interval, 1.15-2.33). Among the 3 subscales, only intellectual activity was significantly associated with stroke (hazard ratio, 1.64; 95% confidence interval, 1.21-2.22). Social role was significantly associated with stroke only among those aged ≥ 75 years (hazard ratio, 1.78; 95% confidence interval, 1.07-2.98). Conclusions.Impaired higher-level functional capacity, especially in the domain of intellectual activity, was a predictor of stroke, even among community-dwelling older adults with independent basic activities of daily living at baseline. Monitoring of higher-level functional capacity might be useful to detect those at higher risk of developing stroke in the future.
