Brief Summary

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, 2 hour glucose of 140-199 mg/dl). The DPP has ended early demonstrating that lifestyle reduced diabetes onset by 58% and metformin reduced diabetes onset by 31%. DPPOS (2002-2013) 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 at risk 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 microvascular disease, CVD risk factors and atherosclerosis, 3) close examination of these topics in men vs women and in minority populations. The major aims of DPPOS-3 (2014-2025) take advantage of the long-term randomized exposure of the study cohort to metformin and the aging of the DPPOS cohort. The metformin exposure and high degree of study retention and adherence (\~85% of the DPPOS cohort continues to attend annual and mid-year visits) allows DPPOS-3 to examine the long-term effects of metformin on cardiovascular disease (CVD) and cancer outcomes, outcomes of great clinical interest and import.

Outcome Measures

Primary Outcomes (4)

• Development of Diabetes.

  Primary outcome for years 2002-2008 defined according to American Diabetes Association criteria (fasting plasma glucose level \>= 126 mg/dL \[7.0 mmol/L\] or 2-hour plasma glucose \>= 200 mg/dL \[11.1 mmol/L\], after a 75 gram oral glucose tolerance test (OGTT), and confirmed with a repeat test).

  Outcomes were assessed from 1996-2008 (approximately 12 years including 6 years of DPP).

• Prevalence of Aggregate Microvascular Complication

  Aggregate microvascular disease is defined as the average prevalence of 3 components: (1) retinopathy measured by photography (ETDRS of 20 or greater); (2) neuropathy detected by Semmes Weinstein 10 gram monofilament, and (3) nephropathy based on estimated glomerular filtration rate (eGFR by chronic kidney disease (CKD-Epi) equation ) (\<45 ml/min, confirmed) and albumin-to-creatinine ratio in spot urine (\> 30mg/gm, confirmed).

  Outcomes were assessed from 2012-2013 (approximately 2 years).

• Total Cancer Except Non-melanoma Skin Cancer

  All primary incident cancers except non-melanoma skin cancer

  Outcomes were assessed from 1996-2020 (approximately 24 years).

• Major Adverse Cardiovascular Events (MACE): Myocardial Infarction (MI), Stroke, or Cardiovascular Death (CVD)

  Defined as MI, stroke and CVD death. These outcomes were collected since randomization and adjudicated by an outcomes committee who are blinded to treatment assignment.

  Outcomes were assessed from 1996-2025 (approximately 29 years).

Secondary Outcomes (5)

• Subclinical Atherosclerosis

  Outcomes were assessed from 2012-2013 (approximately 2 years).

  Outcomes were assessed in visit years starting in 2010, 2012, 2017, 2020.

• Short Physical Performance Battery

  Outcomes were assessed in visit years starting in 2010, 2012, 2017, 2020.

• Frailty

  Outcomes were assessed in visit years starting in 2010, 2012, 2017, 2020.

• Mortality

  Outcomes were assessed throughout follow-up from 1996 to 2022. National Death Index search conducted in 2019 using early release data as of Dec 2018.
