This indicator reports the average percentage of students in grades 9 through 12 at high schools participating in the Youth Risk Behavior Survey (YRBS) who said they had five or more drinks in a row within a couple of hours on one or more of the past thirty days.[i],[ii] The latter definition is consistent with binge drinking, as a blood alcohol concentration of 0.08 percent or higher usually occurs after four or more drinks are consumed within two hours for women and five or more for men (NIAAA, 2012).
[i] The percentages from each participating school within each county were averaged to calculate the county level percentages. One participating school was excluded from county averages due to extreme values.
[ii] 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.
Youth Risk Behavior Survey (YRBS)
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
health organizations. The Youth Risk Behavior Surveillance System was
designed to focus the nation on behaviors among youth related to the
leading causes of mortality and morbidity among both youth and adults
and to assess how these risk behaviors change over time. The Youth Risk
Behavior Surveillance System measures behaviors that fall into six
1. Behaviors that result in unintentional injuries and violence;
2. Tobacco use;
3. Alcohol and other drug use;
4. Sexual behaviors that result in HIV infection, other sexually transmitted diseases, and unintended pregnancies;
5. Dietary behaviors; and
6. Physical activity.
