Sexual Risk Behaviors Can Lead to HIV, STDs, & Teen Pregnancy
Many Young People Engage in Sexual Risk Behaviors
Many young people engage in sexual risk behaviors and experiences that can result in unintended health outcomes.
CDC data show that lesbian, gay, and bisexual high school students are at substantial risk for serious health outcomes as compared to their peers.
Among U.S. high school students surveyed in 20171
- 40% had ever had sexual intercourse.
- 10% had four or more sexual partners.
- 7% had been physically forced to have sexual intercourse when they did not want to.
- 30% had had sexual intercourse during the previous 3 months, and, of these
- 46% did not use a condom the last time they had sex.
- 14% did not use any method to prevent pregnancy.
- 19% had drunk alcohol or used drugs before last sexual intercourse.
- Less than 10% of all students have ever been tested for human immunodeficiency virus (HIV).
21% of all new HIV diagnoses were among young people (aged 13-24) in 2017; 87% were young men and 13% were young women.2

Abstinence from vaginal, anal, and oral intercourse is the only 100% effective way to prevent HIV, other STDs, and pregnancy. The correct and consistent use of male latex condoms can reduce the risk of STD transmission, including HIV infection. However, no protective method is 100% effective, and condom use cannot guarantee absolute protection against any STD or pregnancy.
Schools and Youth Serving Organizations Can Help
School health programs can help young people adopt lifelong attitudes and behaviors that support their health and well-being—including behaviors that can reduce their risk for HIV and other sexually transmitted diseases (STDs).
HIV, STD, and teen pregnancy prevention programs in schools should
- Provide health information that is basic, accurate, and directly contributes to health-promoting decisions and behaviors.
- Address the needs of youth who are not having sex as well as youth who are currently sexually active.
- Ensure that all youth are provided with effective education and skills to protect themselves and others from HIV infection, other STDs, and pregnancy.
- Be developed with the active involvement of students and parents.
- Be locally determined and consistent with community values and relevant policies.
The National HIV/AIDS Strategyexternal icon calls for all Americans to be educated about HIV. This includes knowing how HIV is transmitted and prevented, and knowing which behaviors place individuals at greatest risk for infection. HIV awareness and education pdf icon[PDF – 70 pages] should be universally integrated into all educational environments.
