Sexual Risk Behavior: HIV, STD, & Teen Pregnancy Prevention

Many young people engage in sexual risk behaviors that can result in unintended health outcomes. For example, among U.S. high school students surveyed in 20131
  • 46.8% had ever had sexual intercourse
  • 34.0% had had sexual intercourse during the previous 3 months, and, of these
    • 40.9% did not use a condom the last time they had sex
  • 15.0% had had sex with four or more people during their life
Sexual risk behaviors place adolescents at risk for HIV infection, other sexually transmitted diseases (STDs), and unintended pregnancy:
  • An estimated 8,300 young people aged 13–24 years in the 40 states reporting to CDC had HIV infection in 20092
  • Nearly half of the 19 million new STDs each year are among young people aged 15–24 years3
  • More than 400,000 teen girls aged 15–19 years gave birth in 20094
To reduce sexual risk behaviors and related health problems among youth, schools and other youth-serving organizations can help young people adopt lifelong attitudes and behaviors that support their health and well-being—including behaviors that reduce their risk for HIV, other STDs, and unintended pregnancy.
