WASHINGTON (AP) -- More high school students are using condoms than 20 years ago - but progress has stalled with a lot of work still needed to protect young people from the AIDS virus, government researchers reported Tuesday.
Today, 4 of every 10 new HIV infections occur in people younger than 30, according to the Centers for Disease Control and Prevention - and the teen years, just as youths become sexually active, are key for getting across the safe-sex message.
Using a long-standing survey of high school students' health, the CDC tracked how teen sexual behavior has changed over 20 years. The results are decidedly mixed.
About 60 percent of sexually active high school students say they used a condom the last time they had sex, researchers told the International AIDS Conference. That's an improvement from the 46 percent who were using condoms in 1991.
"This is good news," said Dr. Kevin Fenton, director of CDC's HIV prevention center. But, "we need to do a lot more."
The problem: Condom use reached a high of 63 percent back in 2003.
Black students are most likely to heed the safe-sex message, yet their condom use dropped from a high of 70 percent in 1999 to 65 percent last year, the study found.
If mom and dad get antsy about discussing condoms, well, about half of high school students have had sex, a proportion that hasn't changed much over the two decades, the CDC reported. Today, 47 percent say they've had sex, down just a bit from 54 percent in 1991. Again, black teens made the most progress, with 60 percent sexually active today compared with 82 percent two decades ago.
The more partners, the more risk. Fifteen percent of high school students say they've had four or more partners, down from 19 percent in 1991.
Fenton said part of the problem is that many school systems don't have strong enough sex education policies that include teaching teens about how to prevent HIV. But he cautioned that the CDC study can't link the abstinence-only policies pushed by Congress through the late 1990s and early 2000s to the stalled progress.
Overall, though, a characteristic of the young is to think they're invincible, Fenton added.
Lawrence Stallworth, 20, of Cleveland can attest that they're not. He learned he was infected with HIV at age 17, when he was a high-school senior, after a hospitalization. A black gay man, he's among one of the nation's highest-risk groups.
He's now an Ohio AIDS activist who works to teach young people that they need to protect themselves, and how.
"I want people to have the tools to keep themselves safe," said Stallworth, who at this week's AIDS conference is working with the nonprofit Advocates for Youth to increase young people's awareness of an epidemic that in the U.S., today gets little publicity.
Part of that involves our society getting "better at being more open about being able to talk about sex," Stallworth added. "It's still a taboo issue."
Indeed, at this week's conference, the world's largest AIDS meeting, young gay black men in the U.S. are emerging as a population in special danger from rising HIV infections.
Black gay and bisexual men account for 1 in 500 Americans but 1 in 4 new HIV infections. The odds that a black man who has sex becomes infected rise from 1 in 4 at age 25 to a stunning 60 percent by age 40, said Phill Wilson of the Black AIDS Institute.
But they're not the only ones at risk. The CDC recommends that everyone in the U.S. ages 13 to 65 be tested for HIV at least once. Those at increased risk - such as people who have multiple sex partners or men who have sex with men - should be tested more frequently, at least once a year.
In South Carolina, 18-year-old Quinandria Lee offers an example of the safe sex practices that CDC says more young people should adopt.
Lee was frustrated at her school's abstinence-only focus. She learned about both male and female condoms from the South Carolina Contraceptive Campaign, and last year her principal allowed her to teach her classmates about them. Condoms are the only contraceptive that also protect against HIV infection.
But Lee credits her mother's frank talk about sex with this key protective step: Lee persuaded her boyfriend to go with her to a clinic where both got a clean bill of health before they ever had sex. Still, they use a condom every time.
"It's hard," she said of that get-tested conversation. But "you can't be too sure."
