Nicole Cushman claims in Vice:
"[P]arents seem to be under the impression that teaching this information was going to encourage the kids to go out and have sex."
"We know from decades of research that that's simply not true," she says. "The more we can arm young people with information, the more likely they will wait to have sex."
I know that studies show that accurate Sex Ed - unlike other programs such as abstinence-only - reduces pregnancy and STD rates, but I am not aware of any studies showing that it also increases the time young people will wait to have sex.
I could only find one relevant link (which is currently offline). The preview claims that:
Researcher Douglas Kirby for the National Campaign to End Teen and Unplanned Pregnancy examined studies of prevention programs which had a strong experimental design and used appropriate analysis. Two-thirds of the 48 comprehensive sex ed programs studied had positive effects.
- 40 percent delayed sexual initiation, reduced the number of sexual partners, or increased condom or contraceptive use.
- 30 percent reduced the frequency of sex, including a return to abstinence.
- 60 percent reduced unprotected sex.
It cites: Kirby D. “Sex and HIV Programs: Their Impact on Sexual Behaviors of Young People Throughout the World.” Journal of Adolescent Health 40 (2007) : 206-217.
Does comprehensive Sex Ed increase the time young people wait to have sex, and/or reduce the frequency with which they have sex?
