Progression to Impaired Glucose Tolerance and Type 2 Diabetes in the Korean People-based KNDP Study

This study has been completed.
Information provided by:
Korea University Guro Hospital Identifier:
First received: December 17, 2009
Last updated: June 8, 2010
Last verified: December 2009
Impaired glucose tolerance is a metabolic state between normal glucose homeostasis and diabetes. Previously, prospective studies have shown higher progression rates from IGT to diabetes in other country. But There is no prospective-multicenter based reports in Korea. Therefore, the purpose of this study is to estimate the progression rates to impair glucose regulation and diabetes in the Korean population-based Korea national Diabetes program.
