U.S. High School Students Improve Motor Vehicle-related Health Behaviors
U.S. high school students have shown significant progress over the past two decades in improving many health-risk behaviors associated with the leading cause of death among youth—motor vehicle crashes—according to the 2011 National Youth Risk Behavior Survey (YRBS) released today by the Centers for Disease Control and Prevention. However, youth are engaging in other dangerous practices such as texting and emailing while driving.
Although motor vehicle crashes account for more than 1 in 3 U.S. teen deaths each year, findings from this survey show dramatic improvements during the past 20 years in motor vehicle safety among youth:
- From 1991 to 2011, the percentage of high school students who never or rarely wore a seatbelt declined from 26 to 8.
- From 1991 to 2011, the percentage of students who rode with a driver who had been drinking alcohol during the past 30 days declined from 40 to 24.
- The percentage of high school students who had driven a car during the past 30 days when they had been drinking alcohol decreased from 17 in 1997 to 8 in 2011.
- Between 2009 and 2011 encouraging improvements were also shown in the percentage of students wearing a seat belt, not riding with a driver who had been drinking alcohol and not driving a car when they had been drinking alcohol.
Despite this progress, the YRBS found that the use of technology among youth has resulted in new risks; specifically, 1 in 3 high school students had texted or e-mailed while driving a car or other vehicle during the past 30 days. The survey also found that 1 in 6 had been bullied through email, chat rooms, instant messaging, websites, or texting during the past 12 months. 2011 was the first year the YRBS included questions about bullying through electronic media and about texting or emailing while driving.
“We are encouraged that more of today’s high school students are choosing healthier, safer behaviors, such as wearing seat belts, and are avoiding behaviors that we know can cause them harm, such as binge drinking or riding with impaired drivers,” said Howell Wechsler, Ed.D., M.P.H., director of CDC’s Division of Adolescent and School Health. “However, these findings also show that despite improvements, there is a continued need for government agencies, community organizations, schools, parents, and other community members to work together to address the range of risk behaviors prevalent among our youth.”
The 2011 YRBS results show that high school students still engage in risk behaviors that are harmful to their health and increase their risks for disease and injury:
- Current cigarette use did not change significantly between 2009 (19 percent) and 2011 (18 percent).
- During that same time period, current marijuana use increased from 21 percent to 23 percent although there has been an overall decrease in current marijuana use (from 27 percent in 1999 to 23 percent in 2011).
- Current marijuana use among high school students was more common than current cigarette use (23 percent compared to 18 percent).
About the Youth Risk Behavior Surveillance System
CDC’s YRBS System is the only surveillance system designed to monitor a wide range of priority health risk behaviors among representative samples of high school students at the national, state, and local levels.
National, state, and large urban school district surveys are conducted every two years among high school students throughout the United States. These surveys monitor priority health risk behaviors including unintentional injuries and violence; tobacco, alcohol, and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases, including HIV infection; unhealthy dietary behaviors; and physical inactivity. These surveys also monitor obesity and asthma.
More than 15,000 U.S. high school students participated in the 2011 National YRBS. Parental permission was obtained for students to participate in the survey and student participation was voluntary, and responses were anonymous. States and large urban school districts could modify the questionnaire to meet their needs. The 2011 YRBS System report includes national YRBS data and data from surveys conducted in 43 states and 21 large urban school districts.
The 2011 national YRBS is one of three HHS-sponsored surveys that provide data on substance abuse among youth nationally. The others are the National Survey on Drug Use and Health (NSDUH), sponsored by the Substance Abuse and Mental Health Services Administration -a primary source of statistics on substance use among Americans age 12 and older (www.oas.samhsa.gov/nhsda.htm), and the Monitoring the Future (MTF) study funded by the National Institute on Drug Abuse –part of the National Institutes of Health– and conducted by the University of Michigan’s Institute for Social Research (http://monitoringthefuture.org). The MTF study tracks substance use and related attitudes among students in the eighth, 10th, and 12th grades.
The 2011 YRBS data are available at www.cdc.gov/yrbs.
CDC works 24/7 saving lives, protecting people from health threats, and saving money through prevention. Whether these threats are global or domestic, chronic or acute, curable or preventable, natural disaster or deliberate attack, CDC is the nation’s health protection agency.
