Brief Summary

The prevalence of obesity and diabetes in older adults is increasing. Because older adults are often portrayed as less likely to change long-standing health behaviors, health promotion in this age group has lagged behind others. In fact, little attention has been given to the importance of diabetes prevention in community-dwelling older adults through the implementation of programs that promote healthy nutrition, increase physical activity and improve self-management. The Diabetes Prevention Program (DPP), which demonstrated the benefit of modest weight loss on the reduction of diabetes risk (58% overall reduction with a 71% reduction in the older population), has yet to be translated into widespread public health practice. The overall objective of this protocol is to implement evidence-informed, innovative interventions to increase adoption of findings from comparative effectiveness research (CER) for diabetes management and prevention in South Florida older veterans. Specifically, the proposed study will test the hypothesis that Peer-led Care alone (PC), or activated by technology (TechnAlert-Peer or TAP), is superior to traditional methods of information dissemination (Usual Care or UC) for adoption of CER on prevention and management of diabetes, leading to better self-efficacy and clinical outcomes. The investigators will conduct a 12-month randomized controlled trial in older veterans with prediabetes and diabetes participating in one of the Healthy Aging Regional Collaborative programs. Primary outcomes include changes in self-efficacy, weight, and hemoglobin A1c. Secondary outcomes include changes in blood pressure, lipids, physical function, quality of life, and health care utilization and the evaluation of potential racial/ethnic disparities in the process of adoption of CER for prevention and management of diabetes. This study is expected to accelerate the implementation of CER evidence for diabetes prevention, addressing health and economic challenges in the care of overweight and obese veterans.

Outcome Measures

Primary Outcomes (2)

  • Compare changes in self-efficacy between participants receiving peer-led care (with or without TAP intervention) and those receiving UC over 12 months.

    12 months

  • Compare changes in weight and hemoglobin A1c between participants receiving peer-led care (with or without TAP intervention) and those receiving UC over 12 months.

    12 months

Secondary Outcomes (3)

  • Compare changes in weight, hemoglobin A1c, and self-efficacy between white-non-hispanics and minorities over 12 months.

    12 months

  • Compare changes in blood pressure, lipids, physical function, and quality of life among treatment groups (UC, PC, and TAP).

    12 months

  • Compare changes in health care utilization (physician visits, emergency visits, and days in hospital) among treatment groups (UC, PC, and TAP).

Interventions

An expert patient in the peer-led intervention will provide effective support for patients and families to accelerate adoption of CER for diabetes prevention and management in the elderly. This will lead to better self-efficacy and clinical outcomes. Those veterans enrolled in the MOVE! and HARC programs that have showed success in management of weight and Diabetes will be offered to become peer-leaders. * Weight management success is defined as a loss of at least 5% of the weight since enrollment * Diabetes management will be defined as adequate control of HbA1c and/ or blood pressure and lipids. The potentials peer-leaders will have a pre-assessment test to evaluate diabetes prevention and management knowledge and motivation and support skills.

Also known as: PC
Peer-led care (PC)

Participants in the TAP group will receive mobile phones that will be programmed to monitor specific clinical parameters and promote adoption of CER on prevention and management of diabetes, with protocols developed in part based on the input from the focus groups. These devices display messages, tips, reminders and questions regarding healthy lifestyle and clinical parameters of diabetes, which will be developed using best practice guidelines. Participants will be asked to respond to the questions daily if they can. Also they are asked to provide their daily weight, blood pressure, and glucose levels (the later only for patients with diabetes).
