The number of teens who report having sex is down

Fewer teens are having sex than at any point since 1991, a national survey of U.S. high school students finds. But among those students who are sexually active, fewer are using condoms, raising the risk of contracting sexually transmitted infections.

About 40 percent of teens surveyed in 2017 reported having ever had sex. That’s down from about 54 percent in 1991, the first year the survey was conducted. Of the roughly 29 percent of students who are currently sexually active — defined as having had sexual intercourse with at least one person in the three months before the survey — nearly 54 percent reported that either they or their partner used a condom the last time they had had sex. Ten years ago, about 61 percent of teens reported condom use.

Cora Breuner, a pediatrician specializing in adolescent medicine at Seattle Children’s Hospital, says that pediatricians have been doing a better job educating teens about sex. “The more kids know about it, the less mystique there is about it,” she says, and “the more they want to wait.”

“I’m actually more concerned about the lack of condom use,” says Breuner, who also chairs the American Academy of Pediatrics Committee on Adolescence. She sees two reasons for the drop: Less fear of HIV with the advent of antiretroviral drugs and wider availability of long acting contraceptives, which are very effective at preventing pregnancy. “We are not doing a good job informing kids about protecting themselves from getting sick with infections that can last the rest of their lives and have significant negative outcomes, including infertility and even death.”

Part of a biennial report released by the Centers for Disease Control and Prevention, the new analysis, published on June 14, relied on close to 15,000 surveys from teens in grades 9 to 12 at 144 schools. The report includes information on various health-related behaviors, information that could be used to help guide youth public health policies. For instance:
