This 2009 survey by the CDC looks at health-risk behaviors among young people in 9th through 12th grade. The behaviors studied include those that contribute to injuries and violence, alcohol and drug use, tobacco use, sexual risk behaviors, unhealthy dietary behaviors and physical inactivity.
The study found a large representation of behaviors that contribute to unintentional injury and violence among students. About 28 percent of students had ridden in a vehicle with someone who had been drinking at least once within 30 days before the interview; 9.7 percent of students had driven a car when they themselves had been drinking; 17.5 percent of students had carried a weapon; and 5.6 percent carried a weapon onto school property 30 days before the survey.
The study found 46.3 percent of the students to have tried cigarette smoking at least once in their lifetime and 19.5 percent to have smoked cigarettes within the 30 days before the survey.
Nearly half of the students surveyed said they have had sexual intercourse, and 34.2 percent were currently sexually active. About 61 percent of the sexually active students said they used condoms and 22.9 percent said they used birth control pills or Depo-Provera.
