The Diabetes Prevention Program (DPP) was a multi-center trial examining the ability of an intensive lifestyle or metformin to prevent or delay the development of diabetes in a high risk population due to the presence of impaired glucose tolerance (IGT). The DPP has ended early demonstrating that lifestyle reduced diabetes onset by 58% and metformin reduced diabetes onset by 31%.
The DPPOS is designed to take advantage of the scientifically and clinically valuable DPP participants. This group of participants is nearly 50% minority and represents the largest IGT population ever studied. Clinically important research questions remain that focus on 1)durability of the prior DPP intervention, 2) determination of the clinical course of precisely known new onset diabetes, in particular regarding CVD, CVD risk factors and atherosclerosis and microvascular disease, 3)close examination of these topics in men vs women and in minority populations.
Study Type: | Observational |
Study Design: | Cohort, Prospective |
Official Title: | Diabetes Prevention Program Outcomes Study |
DPPOS participants have blood samples stored at the time of each annual visit. Specimens are stored at the study CBL until after the primary study outcomes are reported. DNA samples were previously collected and are stored at the NIDDK sample repository for DPP participants
