Summary

This study follows 3,600 overweight or obese teenagers who are at high risk for developing type 2 diabetes. Researchers will monitor changes in blood sugar, insulin, and other factors over time to learn how the disease starts. No treatments or medications are given—the goal is simply to gather information to better predict and prevent diabetes in youth.
