Teen Pregnancy Resumes Rise In U.S.

(CBS)  A new Centers for Disease Control and Prevention (CDC).

And sexually-transmitted disease cases have increased, as well.

The report also indicates in 2006, the most recent year for which date was available, about one million young people aged 10 to 24 were reported to have chlamydia, gonorrhea or syphilis. The CDC also said nearly one-quarter of females aged 15 to 19, and 45 percent of females aged 20 to 24 had a human papillomavirus (HPV) infection during 2003-2004.

Also, AIDS cases among males aged 15 to 24 increased from 1997 to 2006, the report said. In 2006, according to the CDC, the majority of new diagnoses of HIV infection among young people occurred among males and those aged 20 to 24.

Other reported findings involved nonfatal sexual assault among teens and young adults. From 2004 to 2006, the CDC found, about 100,000 females aged 10 to 24 visited a hospital emergency department for nonfatal sexual assault. Among that number, 30,000 girls were aged 10 to 14.

"This report identifies a number of concerns regarding the sexual and reproductive health of our nation's young people," Janet Collins, director of CDC's National Center for Chronic Disease Prevention and Health Promotion, said in a news release.

Collins said, "It is disheartening that after years of improvement with respect to teen pregnancy and sexually transmitted diseases, we now see signs that progress is stalling and many of these trends are going in the wrong direction."

On "The Early Show" Monday, co-anchor Maggie Rodriguez asked CBS News medical correspondent Dr. Jennifer Ashton what parents can take away from these statistics.

Ashton said education is the key, citing that the report found one-third of adolescents hadn't received instruction on methods of birth control before age 18.
