Teens and Sex

While the media bombards us with alarming statistics about the number of teenagers having sex, few reports shed light on what might encourage teens to become sexually active in the first place. Three studies offer some insight into sexually active teens: environment, age of partner and perceived family support may affect young people's decisions to have sex.
In a study presented at a meeting of the American Public Health Association (APHA), researchers at the University of Kentucky followed 950 teenagers at 17 high schools in Kentucky and Ohio from 9th to 11th grades. They found evidence that teens who have intercourse tend to think their friends are too, even if they're not. "You're 2.5 times more likely to have sex by the 9th grade if you think your friends are having sex -- whether or not they really are," says Katharine Atwood, assistant professor at the Kentucky School of Public Health. Plus, teens tended to overestimate how many of their friends were sexually active. Only 33 percent of kids in the study had had sex by the 9th grade, but 31 percent said that most or all of their friends had had sex. "If you can persuade them that fewer are having sex than they think," she says, "that can have a significant impact on their behavior."
