Teen pregnancy prevention programs

Evidence rating: Some Evidence

Strategies with this rating are likely to work, but further research is needed to confirm effects. These strategies have been tested more than once and results trend positive overall.

Health Factors  

Teen pregnancy prevention programs can include comprehensive sex education, HIV/STI prevention, youth development, service learning, abstinence approaches, or combinations thereof. Programs can be provided in schools, clinics, or community settings and can be targeted to pre-adolescents, adolescents, teens who are abstinent or teens who are sexually active. Programs also often cover a range of behaviors and attitudes; program components vary by implementer and specific model.

Expected Beneficial Outcomes (Rated)

  • Reduced teen pregnancy

  • Reduced sexual activity

  • Increased use of contraception

  • Reduced incidence of STIs

Other Potential Beneficial Outcomes

  • Increased condom use

Evidence of Effectiveness

There is some evidence that pregnancy prevention programs reduce sexual activity, increase use of contraceptives, reduce STIs1, and reduce teenage pregnancy1, 2, 3. However, effects vary by program and additional evidence is needed to confirm effects4.

Programs that focus on specific skills and take place over longer periods of time may be more effective than shorter or more general programs5. Evidence about the effects of teenage pregnancy prevention programs is strongest for black youth; more studies are needed to confirm effects for other groups, particularly Latinos and small populations at high risk of teenage pregnancy such as youth in foster care and American Indian and Alaska Natives1. There are a wide range of teen pregnancy prevention programs. Program effects and effectiveness can vary based upon population and setting, and local community needs are crucial in determining which program is most appropriate1.

Service learning programs decrease pregnancy rates among adolescents6, 7, and may also delay the initiation of sexual intercourse, reduce frequency of sex, and increase the use of condoms and other contraceptives6, 7, 8, 9. Youth development2 and multi-component programs appear to lower the rate of unintended pregnancy among adolescents3, 4, 7. Comprehensive risk reduction programs reduce risk behaviors such as engagement in sexual activity, frequency of sexual activity, number of partners, and frequency of unprotected sexual activity6, 10, 11, 12. Comprehensive programs increase use of contraception4, 6, 12, 13 and may also reduce pregnancy10, 11, 12 and sexually transmitted infections (STI) among adolescents6, 12

Implementation Examples

The US Department of Health and Human Service’s Office of Adolescent Health administers a grant program that funds research and demonstration of new and innovative pregnancy prevention programs, as well as replication of 31 selected programs, through the Teen Pregnancy Prevention (TPP) Program. These 31 programs were shown to prevent teen pregnancies or births, reduce sexually transmitted infections, or reduce rates of associated sexual risk behaviors in a DHHS-commissioned study14.
