healthy living partnership to prevent diabetes

Conditions: Prediabetes; Obesity

Summary: the healthy living partnership to prevent diabetes (help pd) is a 300-participant randomized trial designed to test the effectiveness of a lay-health counselor led community-based diabetes prevention program in reducing blood glucose in people at risk for developing diabetes mellitus.

social forces have promoted adverse behavioral patterns with respect to physical activity and nutrition resulting in the current epidemics of obesity, the metabolic syndrome and type 2 diabetes mellitus (dm). results from clinical trials such as the diabetes prevention program (dpp) have demonstrated a significant potential for prevention of type 2 dm through lifestyle interventions to promote physical activity, a healthy eating pattern and weight loss. yet these approaches are not being applied in practice. in fact, whether these approaches can be successfully implemented in the community is an unanswered question. the healthy living partnership to prevent diabetes (help pd) was designed to address this knowledge gap in a community setting. it incorporates key translations of prior research to enhance logistical and fiscal feasibility and long term dissemination, including the use of a group-based, rather than an individual-based, intensive lifestyle behavioral intervention employing professionals and community health workers (chws), and delivery of the intervention in the community setting via expansion of an existing diabetes education program (dep). the trial has been continued for an additional 5 years, and the primary goal of the continuation is to test the long-term glucose lowering effects of the help pd intervention by randomizing the lifestyle group to continued group maintenance or a self-directed maintenance condition and to follow the uc group for additional comparison purposes. demonstrating the longer term effectiveness of help pd will represent a key step in establishing the value of this approach to translation of dm prevention into the community. this crucial evidence will be used to support reimbursement policy for dm prevention, dissemination of the help pd chw approach and generalization to other behaviorally influenced chronic diseases.
