Preventing sexual risk behaviors and pregnancy among teenagers: linking research and programs.

Abstract

Recent trends in adolescent sexual behavior offer mixed messages. It is very encouraging that teenagers’ overall rates of sexual activity, pregnancy and childbearing are decreasing, and that their rates of contraceptive and condom use are increasing. 1 However, the proportion of young people who have had sex at an early age has increased. 2 Moreover, while adolescent females’ contraceptive use at first sex is rising, their use at most recent sex is falling. 3 There is general consensus that the proportion of teenagers who engage in behaviors that put them at risk of pregnancy and of HIV and other sexually transmitted infections (STIs) remains too high. Each year, approximately one million young women aged 15–19—or one-fifth of all sexually active females in this age-group—become pregnant; the vast majority of these pregnancies are unplanned. 4 In the United States, the risk of acquiring an STI is higher among teenagers than among adults. 5 Moreover, rates of unprotected sexual activity, STIs, pregnancy and childbearing continue to be substantially higher among U.S. adolescents than among young people in comparable industrialized countries. 6 Research has also begun to highlight an alarmingly high rate of involuntary sex among young people. In the 1995 National Survey of Family Growth, 13% of 15–19-year-old females reported that they had been forced to have sex. 7 When asked about their first sexual experience, 22% of 15–44-year-old women for whom it occurred before age 15 reported that the act was involuntary, as did 16% of those who first had sex before age 16. Involuntary sexual activity is typically unprotected and thus puts its victims at very high risk of pregnancy and STIs. Finally, recent research and clinical observations suggest that a substantial proportion of teenagers, including those who report having never had vaginal sex, are engaging in oral sex. 8 This trend has negative implications for teenagers’ sexual health because many seem unaware that STIs can be acquired through unprotected oral sex.
