Effective HIV and STD Prevention Programs for YouthPrint Version [pdf 174K]
A Summary of Scientific Evidence
Just as schools are critical settings for preparing students academically, they are also vital partners in helping young people take responsibility for their own health. School health programs can help youth adopt lifelong attitudes and behaviors that support overall health and well-being—including behaviors that can reduce their risk for HIV and other sexually transmitted diseases (STDs).
HIV/STD prevention programs implemented by schools include prevention education programs designed specifically to reduce sexual risk behaviors and youth asset-development programs, which provide adolescents with more general skills that help them engage in healthy behaviors and solve problems.
Effective HIV/STD Prevention Education Programs
Research shows that well-designed and well-implemented HIV/STD prevention programs can decrease sexual risk behaviors among students, including
- Delaying first sexual intercourse.1-4
- Reducing the number of sex partners.4-7
- Decreasing the number of times students have unprotected sex.8-9
- Increasing condom use.8,10-11
A review of 48 research studies found that about two-thirds of the HIV/STD prevention programs studied had a significant impact on reducing sexual risk behaviors, including a delay in first sexual intercourse, a decline in the number of sex partners, and an increase in condom or contraceptive use. Notably, the HIV prevention programs were not shown to hasten initiation of sexual intercourse among adolescents, even when those curricula encouraged sexually active young people to use condoms.12-13
In addition to determining programs that are most effective in reducing sexual health risk behaviors among youth, scientists also have identified key common attributes among these programs. Effective HIV/STD prevention programs tend to be those that
- Are delivered by trained instructors.
- Are age-appropriate.
- Include components on skill-building, support of healthy behaviors in school environments, and involvement of parents, youth-serving organizations, and health organizations.12
Traits common among effective programs should guide the development of curricula and the integration of program activities for HIV/STD prevention in schools and communities.
Youth Asset-Development Programs: A Promising Approach
A second approach to HIV prevention seeks to increase the skills of children and adolescents to avoid health risks, including sexual risk behaviors.14-17 Youth asset-development programs, including those conducted in schools, teach youth how to solve problems, communicate with others, and plan for the future. They also help youth develop positive connections with their parents, schools, and communities.
Youth asset-development programs typically address multiple health risk behaviors and are commonly provided to children and adolescents over a number of years. Evidence indicates that these programs can be associated with long-term reductions in sexual risk behaviors.22
Reducing Risk Behaviors and Saving Money
Effective HIV/STD prevention programs also are cost-effective. An economic analysis of one school-based sexual risk reduction program found that for every dollar invested in the program, $2.65 was saved in medical costs and lost productivity.18 Other studies have found similar savings for HIV prevention programs focusing on youth who are at disproportionate risk for HIV, including young gay and bisexual men19-20 and urban African American male adolescents.21
CDC’s Ongoing Efforts To Identify and Implement Effective HIV/STD Prevention Programs for Youth
CDC’s Division of Adolescent and School Health (DASH) supports rigorous evaluation research and other projects to identify the types of programs and practices that can reduce sexual risk behaviors among youth:
- DASH has supported the development and evaluation of
- All About Youth, a randomized, controlled trial testing two HIV/STD education programs for middle school students: one that emphasizes sexual abstinence until marriage, and one that emphasizes abstinence in conjunction with skill-building activities for condom and contraceptive use.
- Linking Lives, a program designed to supplement school-based curricula by building parents’ skills to help their middle school children reduce sexual health risks.
- DASH and CDC’s Division of Reproductive Health collaborated with partners to publish a systematic review of the growing body of evidence on positive youth development approaches for reducing HIV, sexually transmitted infections, and unintended pregnancy.22
- DASH scientists
- Analyze research on program effectiveness.
- Develop guidelines for best practices in school-based HIV prevention.
- Create tools to help schools implement the guidelines, such as the Health Education Curriculum Analysis Tool, which integrates research findings and national health education standards to help school districts select or develop health education curricula that are most likely to reduce sexual risk behaviors among the youth they serve.
