Translating the Diabetes Prevention Program: a comprehensive model for prevention training and program delivery.
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 setting s. 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 nonr and omized prospect i ve 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 > or=25 kg/m(2 ) 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 be successful and was effective in reducing diabetes and cardiovascular disease risk factors in this group of high-risk individuals
