"search" : Search for an exact word or phrase
-search : Exclude a word. Add a dash (-) before a word to exclude all results that include that word.
OR : Search for either word. If you want to search for pages that may have just one of several words, include OR (capitalised) between the words. For example, "labor" OR "labour" will show results containing pages with "labor" and "labour". Without the OR, your results will show only pages that match all terms.
intitle: Search for a word or phrase. Unlike the Title search field below the Keyword search field, you can combine terms. For example: intitle:female OR intitle:women will show results containing pages with "female" and "women" in the title.
intext: Search only in the description text field of the page. This field usually contains the abstract or summary of the publication.

- Spanish PLS Description: Altas tasas de actividad sexual y de embarazos y partos de mujeres adolescentes, particularmente en Estados Unidos, han llevado a desarrollar una amplia gama de iniciativas para prevenir el embarazo precoz, algunas con énfasis en los métodos anticonceptivos y otras promoviendo la abstinencia sexual como principal medio de reducción de dichas tasas. Esta revisión analiza la eficacia de los programas de prevención de embarazo precoz para disminuir las tasas de actividad sexual, alentar el uso de métodos anticonceptivos y reducir los embarazos entre mujeres adolescentes.
About this systematic review
This Campbell systematic review examines the effectiveness of teenage pregnancy prevention programs in promoting abstinence, encouraging the use of contraception and reducing the likelihood of pregnancy among teens. The review summarise findings from 31 studies conducted in the US or in developed countries with higher than average rates of unplanned teen pregnancy, such as Canada, England, New Zealand, and Australia.
What are the main results?
Taken together, the findings for each of the first three types of interventions one-time consultations, sex education programs focused on contraception, and sex education programs focused on promoting abstinence show no evidence of having reduced sexual activity or pregnancy rates among participating youth.
The most promising results are for multi-component youth development programs, which resulted in modest reductions (six percentage points) in pregnancy rates among participants as compared with their control group counterparts. The impacts were larger for females than males.
- too little evidence to make specific judgments about one-time consultations
- limited evidence regarding sex education programs with an abstinence focus
- no consistent evidence that that sex education programs altered the likelihood that youth would initiate sex, would risk pregnancy, or would become (or get someone) pregnant
- the most promising results are for the more intensive multi-component youth development programs serving higher risk adolescents. Moreover, within this category, the results tend to be most favorable for females. However, there is a paucity of rigorous evaluations of such programs, and further replication and evaluation is warranted.
While the body of knowledge in this field is continually grow ing, th is review highlights the relative dearth of evidence to jud g e the ove ra ll ef f ectiven ess of partic ular inte rven tion stra tegies. For this reason, furth e r research and evaluatio n is necessary, includ ing studying pr o g ram s that have not yet been evaluated rigorously and program s that have been replicated and are serving new populations of adolescents in different communities. Once a larger body of m o re sim ilar program s have been ev aluated rigorous ly and reported consistently, then it will be possible to pool the evidence to m a ke more concrete conclusions regarding program efficacy.
