Multi-component interventions to prevent teen pregnancy
Multi-component interventions are broad-based programs that aim to reduce risky behaviors in young people through various combinations of education and skills building. They may take place in schools or in the community at multiple levels and activities can include classroom instruction, mentorship, service learning or volunteering, work experience and life skills, and contraceptive education or services1, 2. Programs may also include efforts to create systemic change to improve delivery of sexual and reproductive health care3.
What could this strategy improve?
Expected Benefits
Our evidence rating is based on the likelihood of achieving these outcomes:
Reduced teen pregnancy
Potential Benefits
Our evidence rating is not based on these outcomes, but these benefits may also be possible:
Reduced risky sexual behavior
Increased use of contraception
What does the research say about effectiveness?
There is some evidence that multi-component interventions reduce teen pregnancy1, 2, including programs in schools4, and reduce unprotected sexual intercourse1. Programs appear to be particularly effective among female participants, but do not have a significant impact on male participants1, 2. Additional evidence is needed to confirm effects.
Intensive programs designed for higher risk youth, such as populations with low incomes and from minority backgrounds, appear to be most effective1. In community-wide interventions, increasing amounts of support and technical assistance provided by community-based organizations to other partners appears to increase the provision of contraceptives and the number of youth receiving interventions, particularly when working directly with school systems5. More broadly, sexual and reproductive health interventions appear to be more successful when they are multi-component, delivered at multiple levels and in multiple settings6.
Implementing large community-wide initiatives can require significant training and technical assistance7, 8. An analysis of the Pathways/Senderos Center in Connecticut suggests that multi-component interventions can be cost effective in the long run9.
How could this strategy advance health equity? This strategy is rated potential to decrease disparities: suggested by intervention design.
Multi-component interventions to prevent pregnancy in youth have the potential to decrease disparities in unplanned pregnancy if they are designed for those most at risk. Many multi-component interventions are designed for populations with low incomes and from minority communities1, and available evidence suggests multi-component programs in schools can reduce pregnancy in disadvantaged youth4. A small pilot study of a community-wide, culturally appropriate intervention for Native youth suggests it has the potential to increase self-efficacy and condom use, agreement with cultural attitudes toward pregnancy, and increase communication between parents and children12. More broadly, sexual and reproductive health interventions that are tailored and culturally appropriate appear to be more successful6.
What is the relevant historical background?
Teen pregnancy rates have been declining in the U.S. since 199113 but are still higher than in the industrialized world, and racial and geographic disparities exist within the country14. In rural communities, lack of sexual and reproductive health education and services increases risks for adolescent pregnancy15. Birth rates remain high for young women of color14, 16; American Indian and Alaska Native teens have the highest birth rates, and Hispanic and Black teens’ birth rates are two times higher than that of white teens14.
Teen pregnancy prevention programs are often built on Christian perspectives around when it is acceptable to have children (i.e., after marriage). Pregnancy prevention programs should consider communities’ cultural attitudes and beliefs around pregnancy, particularly communities that have suffered from colonization and Christian cultural repression, such as Native communities12.
Equity Considerations
- Do adolescents in your community have access to the necessary knowledge and resources to prevent pregnancy and STI infections?
- Are existing programs culturally and linguistically appropriate, and inclusive of all gender identities and sexual orientations? Are there any systematic barriers to accessibility?
- Who can you partner with in the community to determine what type of programming may be useful and accepted?
