1097-P: Comparative Effectiveness of Diabetes Prevention Program Implementation Strategies
2021
Background: In the US Diabetes Prevention Program (DPP) trial, a lifestyle intervention program focused on changes in diet and physical activity led to a 58% reduction in risk of developing type 2 diabetes. A variety of modifications to the DPP have been tested in clinical trials. We sought to compare the effects of different strategies for implementation of the US DPP on weight and other cardiometabolic outcomes. Methods: We conducted systematic searches of MEDLINE and Embase from January 2002 to August 2020. We included randomized controlled trials of adults that tested the effect of an intervention based on the US DPP on change in weight. Studies of at least 6 months duration were included. Two investigators independently extracted data. DPP implementation strategies were classified into eight different categories. Results: A total of 30 comparisons from 28 articles with 8,284 participants were included. Different strategies for implementing the DPP led to significant decreases in change in weight in the DPP compared with control arms during follow-up (Table). These strategies included intervention delivery through group sessions or combination of group and individual sessions. Additionally, interventions delivered by telehealth or by a combination of in-person and telehealth were effective. Conclusion: A number of different strategies for implementing the DPP lead to clinically meaningful decreases in weight. Disclosure K. S. Dorans: None. K. T. Mills: None. Y. Feng: None. A. A.
