G-CREDIT (Gangnam-Cohort for Risk Evaluation of Diabetes and Impaired Glucose Tolerance)

Not yet recruiting

• Conditions: Impaired Glucose Intolerance; Type 2 Diabetes

• Registration Number: NCT02726256
• Lead Sponsor: Yonsei University

Brief Summary

The prevalence of type 2 diabetes has consistently increased and type 2 diabetes can cause many types of vascular complications. Diabetes develops due to glucose intolerance. Early detection and intervention in the stage of glucose intolerance makes it afford to prevent overt diabetes and its complications. This study was designed to make a cohort of korean patients with glucose intolerance to construct a long term database about clinical characteristics of these patients.
