Primary outcomePrimary: Change in Cardiovascular Endurance — 20 yards — p=<0.05
Summary
The majority of older Veterans do not meet the minimum healthy diet or physical activity recommendations, despite known benefits. Identifying novel ways to increase adherence to rehabilitation programs that improve dietary quality and physical activity may reduce the risk of disability in older Veterans. Peer-based interventions may be one method to facilitate lasting behavioral change since peers often share a common culture and knowledge about the problems that their community experiences. The investigators propose to develop and evaluate a novel peer-led diet and exercise intervention that targets older Veterans with multiple chronic health conditions. Successful development and pilot of this intervention will provide the preliminary data for a larger multisite trial focused on the use of peer-led interventions to improve long-term compliance to lifestyle interventions in older Veterans.
