Definition
Estimates for non-overweight and non-obese students are based on self-reported height and weight, which are used to generate
Body Mass Index (BMI) calculations.
Numerator
Number of high school students who reported that they are neither overweight nor obese
Denominator
Number of high school students responding to the YRBS survey
Data Interpretation Issues
Since these estimates are based on a sample and not the entire population, the percentage of high school students who are
neither overweight nor obese may differ from the "true" prevalence of that characteristic in the North Carolina population
simply by chance. Confidence intervals take this error into account and present a range in which the "true value" is likely
to fall.
For more information on how to interpret confidence intervals, please see: http://www.schs.state.nc.us/SCHS/champ/technical.html
Why Is This Important?
"Overweight and obese youth are more at risk to be overweight or obese adults. They are also more likely to have high cholesterol
and high blood pressure?both risk factors for cardiovascular disease. The percentage of youth with type 2 diabetes has increased
significantly with the rise in overweight and obesity." - North Carolina Institute of Medicine. Healthy North Carolina 2020:
A Better State of Health.

Data Notes
BMI is computed as weight in kilograms divided by height in meters squared (kg/m*m). BMI is an intermediate variable used
in defining overweight and obesity. Underweight indicates BMI is less than 18.5, Recommended Range indicates BMI is 18.5 to
24.9, Overweight indicates BMI is 25.0 to 29.9 and Obese indicates BMI is 30.0 or greater.
The YRBS survey is only administered every other year; therefore, results are not available on an annual basis.
The HNC 2020 target, which is the target to be reached by 2020, is repeated in the data table for graphing purposes.
