LIFE 2: IMPROVING FITNESS AND FUNCTION IN ELDERS

Hayden B. Bosworth, PhD, Co-Investigator

Project Number XVA 21-007 funded by RR&D.
July 1, 2004 - June 30, 2008


Project Background

Physical inactivity contributes greatly to the health care burden of older adults and is associated with a high prevalence of functional limitations, morbidity, and disability. Rates of physical inactivity are highest among older adults. Older veterans, compared non-veteran older adults, are more likely to be physically inactive and report more limitations in physical function. Increasing physical activity among older veterans is a promising approach to reduce the burden of chronic disease and its associated functional limitations.

Project Objectives

The purpose of this study is to determine whether a 12-month physical activity counseling program, compared to usual care, improves physical performance in a sample of older veterans (n=380). The primary physical performance outcome is change in gait speed. Secondary objectives include examination of the effect of intervention between the two groups (intervention and usual care) on physical activity, self-reported physical function, and health-related quality of life. We also will estimate health care costs between the two groups to determine the short-term economic impact of the counseling in the VHA.

Project Methods

All consented patients will receive a baseline computer assisted interview and physical performance test to be repeated quarterly for one-year. The primary outcome is change in gait speed, which is highly predictive of subsequent institutionalization and mortality. Secondary outcome measures include: the SF-36 physical function and other relevant subscales, health-related quality of life, physical activity, self-efficacy, and personal functional goals. Differences between groups for non-routine outpatient clinic use and hospitalization will be explored. The cost of providing an intensive intervention (relative to the cost of usual care) will be calculated relative to functional changes between groups.

Project Findings

None at this time.

Project Status

Startup activities.

Project Impact

Because approximately 50% of veterans over age 74 have a limiting disability, it is imperative to explore strategies that will alter the course of functional decline of our aging veterans. The proposed project has the potential to have a significant positive impact on the health care of our aging veterans.
