Biannual Report Documents Dangerous Behaviors
The CDC has produced the YRBS every two years since 1991 in order to identify, measure, and track trends in the behaviors that put high schoolers' lives and health in danger. More than 15,000 boys and girls responded to the 2011 national survey. Additional data came from 43 statewide questionnaires as well as from surveys conducted in 21 large urban school districts around the country.
The 168-page report is full of news both good and bad: Over the past two years, fewer students learned about AIDS and HIV infection from their teachers, more students are obese, and the number of suicide attempts rose. On the other hand, binge drinking decreased and more students ate their vegetables.
"Despite progress, there is still much work to do," says Wechsler. "Teens are still engaging in risky behaviors."
The Good and the Bad
Here is a selection of the report's findings:
- 87.5% of teen bicyclists rarely or never wear helmets.
- Nearly 10% of teens had been physically abused by a boyfriend or girlfriend.
- Eight percent had been forced to have sex.
- One out of five students had been bullied at school.
- Nearly 16% of students had considered suicide, and nearly 8% attempted suicide in the previous 12 months.
- Eighteen percent of students said they had smoked cigarettes in the previous month. Twenty-three percent had smoked marijuana.
- Nearly 40% of teens report drinking alcohol recently, compared to 50% 10 years ago.
- One in five students had taken prescription drugs such as Ritalin and OxyContin without a prescription.
- One-third of students report being sexually active. Sixty percent of them use condoms. About 13% use no protection at all.
- Thirteen percent of students missed breakfast every day in the seven days prior to the survey.
- Just under 50% of students got 60 or more minutes of exercise five days a week.
- The number of teens who have had asthma rose from 18.9% to 23% between 2003 and 2011. About 12% say they have it now.
- About 11% of teens report regularly using sunscreen, while 13% have used an indoor tanning bed at least once over the past year.
