Summary

This study followed nearly 5,000 U.S. teenagers from 10th grade through young adulthood (2009-2016) to learn how their health, habits, and risks change over time. Researchers collected surveys, physical measurements, and genetic data to understand what helps teens stay healthy or start risky behaviors like substance use and unsafe driving. The goal was to identify factors that promote positive health, not to test a treatment.
