Observational clinical trial studying the long term effect of diet and exercise and the diabetes medication, metformin, on the delay of type 2 diabetes in participants of the Diabetes Prevention Program (DPP). 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. More than 87% of the original surviving DPP cohort has joined DPPOS as of December, 2007 and, to date, after 5 years of DPPOS and 10 years of combined DPP/DPPOS, 93% of the DPPOS cohort continue to attend annual follow-up visits. Interim analyses performed after 5 years of DPPOS have demonstrated a durable effect of diabetes prevention associated with the lifestyle and metformin interventions with 34 and 19% reductions in diabetes incidence, respectively, compared with the placebo group. Interim analyses also reveal significant reductions from baseline in CVD risk factors in the lifestyle intervention group, but with decreased utilization of glucose-lowering and lipid-lowering medications. Analyses of the participants in the placebo group who have developed diabetes during DPP/DPPOS, compared with those who have remained non-diabetic, reveal an increased frequency of retinopathy and microalbuminuria. The current, updated protocol describes the DPPOS including the revisions incorporated to complete the second five-years of the 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 NIDDKsample repository for DPP participants.
