- Abstract
Background: The Diabetes Prevention Program (DPP) demonstrated that lifestyle intervention reduces risk for type 2 diabetes and the metabolic syndrome. A universal framework for translation of multiple aspects of the DPP intervention, including training, support, and evaluation is needed to enhance treatment fidelity in a variety of settings. Purpose: This study aims to develop a comprehensive model for diabetes prevention translation using a modified DPP lifestyle intervention. Methods: The DPP lifestyle intervention was adapted to a 12-session group-based program called Group Lifestyle Balance for implementation in the community setting. A model for training and support mirroring that of the DPP was developed for prevention professionals administering the program. The process of training/support and program implementation was evaluated for feasibility and effectiveness using a nonrandomized prospective design in two phases (N=51, Phase 1: 2005-2006; N=42, Phase 2: 2007-2009; data analysis completed 2008-2009). A total of 93 nondiabetic individuals with BMI ≥25 kg/m2 and the metabolic syndrome or prediabetes participated. Measures were collected at baseline and post-intervention for all and 6 and 12 months post-intervention for Phase 2. Results: Significant decreases in weight, waist circumference, and BMI were noted in both phases from baseline. Participants in Phase 2 also demonstrated decreases in total cholesterol, non-HDL cholesterol, and systolic and diastolic blood pressure that were maintained at 12 months. Average combined weight loss for both groups over the course of the 3-month intervention was 7.4 pounds (3.5% relative loss, p<0.001); 23.8% and 52.2% of those who completed the program reached 7% and 5% weight loss, respectively. More than 80% of those achieving 7% weight loss in the Phase-2 group maintained their weight loss at 6 months. Conclusions: A comprehensive diabetes prevention model for training, intervention delivery, and support was shown to
