简要总结
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.
详细描述
Over the next ten years the share of Veterans age 65+ years will increase to over 50% of the total Veteran population. The ability to safely maintain mobility with aging is critical. Older Veterans with multiple chronic health conditions are more likely to experience mobility decline and report reduced physical activity levels and poor dietary quality. While a multitude of interventions have attempted to address poor diet and physical inactivity in older adults; most have utilized resource-intensive professionally led diet OR exercise interventions, and few have focused on the unique needs of older Veterans. Peer support offers a potentially low-cost, easily scalable approach to encourage long-term dietary and physical activity change.
In this proposal the investigators seek to develop and pilot a 12-week peer-led lifestyle intervention that targets older Veterans with multiple chronic health conditions and dysmobility, in two diverse urban areas with a high percentage of underrepresented minority Veteran populations (Baltimore, MD and San Antonio, TX). The investigators will develop a theory-driven, peer-led nutrition and exercise intervention tailored for older Veterans with dysmobility. The investigators will also determine the feasibility and acceptability of the peer-led intervention as well as the estimated magnitude and potential impact on selected outcomes (i.e diet quality and mobility) in older Veterans with dysmobility and multiple chronic health conditions.

结局指标
主要结局
Change in Cardiovascular Endurance
时间窗: 12-weeks
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.
Change in Diet Quality as Measured by the HEI Score
时间窗: 12-weeks
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.
次要结局
- Change in Mobility as Measured by the 30 Second Chair Stand Test(12-weeks)
