Brief 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.

Outcome Measures

Primary Outcomes (2)

• Change in Cardiovascular Endurance

  Cardiovascular endurance will be assessed with the distance covered during a six-minute walk test. The distance covered from baseline will be compared to post 12-week intervention.

  12-weeks

• Change in Diet Quality as Measured by the HEI Score

  Food records will be gathered and analyzed using the automated self-administered recall system (ASA24) to evaluate diet quality. Results from baseline will be compared to those after 12 weeks of intervention. The Healthy Eating Index (HEI) is a summary score describing dietary quality on a 0-100 scale; higher scores indicate better diet quality.

  12-weeks

Secondary Outcomes (1)

• Change in Mobility as Measured by the 30 Second Chair Stand Test
