Conventional and Metabolomic Predictors of Prediabetes & Insulin Resistance
2021年9月14日 更新者:Joyce Lee、University of Michigan
The purpose of this study is to evaluate the longitudinal test performance of an array of conventional biomarkers of glycemia, including Hemoglobin A1c (HbA1c), and novel metabolomic biomarkers for identifying progression of glucose tolerance (normal to prediabetes or prediabetes to diabetes) in an overweight and obese pediatric cohort.

研究人群
The study population will consist of normal weight, overweight or obese individuals aged 8 to 17 years at visits #1 and #2, and can be as old as 22 years for follow-up visits #3 and #4.
Participants will be recruited from a variety of sites including University Michigan clinical sites, non-University of Michigan clinical sites, schools in the local area, and the University Michigan medical school campus.
Participants from Group 2 (visits #3-4) completed visits #1-2 in 2007-2013 and formally agreed to be re-contacted for study purposes.
