Associations of physical activity with performance-based and self-reported physical functioning in older XXXX : the Honolulu Heart Program.

OBJECTIVE: To examine the association of self-reported physical activity with performance-based and self-reported physical functioning measured 3 to 5 years later. DESIGN: A population-based, longitudinal study. SETTING: The island of Oahu, Hawaii. @entity1 : Subjects were 3640 Japanese-American @entity1 older than 70 years of age. MEASUREMENTS: Estimated daily energy expenditure evaluated from self-reported engagement in a variety of activities determined from a mail survey in 1988; physical functioning status determined from both self-report and performance-based measures 3 to 5 years later. The effect of physical activity on physical functioning scores was determined through multiple logistic regression and analysis of covariance techniques for subjects who had @entity102 as well as those in a healthy subsample. RESULTS: For the healthy subsample, those who were highly active in 1988 were more likely to have optimal function for the basic activities of daily living score (odds ratio 2.3; confidence interval (CI) 1.1 to 4.9), home management skills score (odds ratio 1.5; CI 1.1 to 2.1), and physical endurance-type tasks score (odds ratio 1.7; CI 1.2 to 2.4) than subjects classified as low active. A significant linear trend was found additionally across physical activity level for time to walk 10 feet and grip strength (P values < .001). Similar results were found for subjects with @entity102 ; however, most of the benefit of physical activity for this subsample occurred for subjects who were at least physically active at a moderate level. CONCLUSION: Engaging in physical activity is predictive of a high level of physical functioning in older @entity1 with and without @entity102 . Participation in at least moderate physical activity may be sufficient to maintain optimal physical functioning in subjects afflicted with @entity102 .
