This indicator reports on the percentage of students in grades 9 through 12 at high schools participating in the Youth Risk Behavior Survey (YRBS) who are overweight or obese based on a calculation of Body Mass Index (BMI).[i] Participating students provided their age, height, and weight. From this information, BMI was calculated and students were categorized as underweight, average, overweight, or obese. Overweight is defined as a BMI at or above the 85th percentile and lower than the 95th percentile for children of the same age and sex. Obesity is defined as a BMI at or above the 95th percentile for children of the same age and sex (CDC).
[i] The data used in this study were not weighted and represent only those students who participated in the survey. Inferences should not be made to any non-participating students. Confidence intervals cannot be applied to unweighted data.

The YRBS is one component of the Youth Risk Behavior Surveillance System
(YRBSS) developed by the Centers for Disease Control and Prevention in
collaboration with representatives from state and local departments of
education and health, other federal agencies, and national education and

2. Tobacco use;
3. Alcohol and other drug use;
4. Sexual behaviors that result in HIV infection, other sexually transmitted diseases, and unintended pregnancies;
