Unprotected sexual intercourse and multiple sex partners place young people at risk for HIV infection, other sexually transmitted diseases (STDs), and pregnancy. Each year, there are approximately 15 million new STD cases in the United States, and about one-fourth of these are among teenagers.1 Nearly 900,000 adolescents under the age of 19 become pregnant.2 In 2003, 47% of high school students had ever had sexual intercourse, 14% of high school students had four or more sex partners during their lifetime, and 37% of sexually active high school students did not use a condom at last sexual intercourse.3

National, State, and Local Programs

CDC's Division of Adolescent and School Health (DASH) supports the development and implementation of effective health promotion policies and programs that address priority health risks among youth.

Project Partners provides information on DASH funded state, local, and territorial education agencies, and national non-governmental organizations. These partners are funded to help build and/or strengthen their capacity to improve child and adolescent health.

Registries of Effective Programs lists federally sponsored registries that include programs effective in reducing youth risk behaviors.

Program Evaluation Materials provides resources for using program evaluation to better document program activities, report achievements, and improve program effectiveness.
