Adolescent Obesity Prevalence: Trends Over Time (2003-2019)
The Youth Risk Behavior Surveillance System (YRBSS) monitors six types of health risk behaviors as well as the prevalence of select health conditions and diseases, including obesity, among youths. As part of the YRBS survey, high school students report on their own behaviors as well as their height and weight, which are used to calculate Body Mass Index (BMI) percentile. These self-reported data are useful for tracking the proportion of high school students with obesity (BMI >95th percentile) over time.
