When second-to-last we checked, teens were getting much better at using contraception. But now, as it turns out, they’re slacking. Yet they’re still having the same amount of sex. Problem.

From a Guttmacher Institute press release today: “After major improvements in teen contraceptive use in the 1990s and early 2000s, which led to significant declines in teen pregnancy, it is disheartening to see a reversal of such a positive trend,” says lead author John Santelli, M.D., chair of the Heilbrunn Department of Population and Family Health at Columbia University Mailman School of Public Health and Guttmacher Institute senior fellow. “Teens are still having sex, but it appears many are not taking the necessary steps to protect themselves from unwanted pregnancy or sexually transmitted infections.”

Why the decline? “The authors suggest that the recent decline in teen contraceptive use since 2003 could be the result of faltering HIV prevention efforts among youth, or of more than a decade of abstinence-only-until-marriage sex education that does not mention contraception unless it is to disparage its use and effectiveness.”

That’s just what we’ll continue to do about ab-only ed.
