Summary

This study tests the hypothesis that non-diabetic individuals with a high genetic risk score for type 2 diabetes have impaired glucose tolerance and insulin resistance compared to those with a low genetic risk score for type 2 diabetes.

Description

The study team will recruit individuals based on genetic risk score for type 2 diabetes from the biobank populations who have agreed to be recontacted for future research. Each participant will undergo a frequently sampled four-hour oral glucose tolerance test and whole body DXA scan (dual-energy X-ray absorptiometry) in addition to baseline laboratory and history assessment.

Condition Diabetes Mellitus, Type 2, Genetics
Treatment 75g glucose beverage (Glucola, Trutol, or similar brand), DXA, whole body
