I wonder why we haven’t heard anything about this study from the University of Pennsylvania Med School? Sixth and seventh grade African American students were randomly sorted into a control group, an abstinence only class, a safer-sex class and a combined abstinence plus safer sex class.

an abstinence-only intervention for pre-teens was more successful in delaying the onset of sexual activity than a health-promotion control intervention. After two years, one-third of the abstinence-only group reported having sex, compared to one-half of the control group. The study by researchers at the University of Pennsylvania appears in the February 1 edition of the Archives of Pediatrics & Adolescent Medicine.

While abstinence-only intervention did not eliminate sexual activity all together, this is the first randomized controlled study to demonstrate that an abstinence-only intervention reduced the percentage of adolescents who reported any sexual intercourse for a long period, in this case two years, following the intervention.

“It is extremely important to find an effective intervention that delays sexual activity; the younger someone is when they have sex for the first time, the less likely they are to use condoms,” said lead author John B. Jemmott III, PhD, professor of Communication in Psychiatry and of Communication at the University of Pennsylvania’s School of Medicine and Annenberg School for Communication. “Abstinence-only interventions may have an important role in delaying sexual activity until a time later in life when the adolescent is more prepared to handle to consequences of sex. This can reduce undesirable consequences of sex, including pregnancy and sexually transmitted infections like HIV/AIDS.”…

Researchers determined that none of the interventions had significant effects on consistent condom use or unprotected sex. For those who lost their virginity during the two year study, there was no difference in consistent condom use between the abstinence-only intervention and the control group.

The abstinence-only intervention was based on principles shown to be effective in reducing the risk of sexually transmitted infections (STIs), including HIV/AIDS, and did not use a moralistic tone or portray sex in a negative light. It encouraged abstinence as a way to eliminate the risk of pregnancy and STIs. During the 8-hour abstinence-only session, study facilitators used brief and interactive small group activities to build the pre-teens’ knowledge of HIV and STIs, bolster beliefs supporting practicing abstinence, and improve skills and confidence to help negotiate abstinence and resist pressure to have sex.

The researchers noted that, in the United States, the consequences of early sexual involvement – including HIV, other STIs, and unintended pregnancies – are especially great among African American adolescents. An effective abstinence-only intervention could stave off unwanted consequences until adolescents mature and are prepared to handle the consequences of sex.

You would think this would make the news, especially since just last week, the Usual Suspects blamed abstinence programs for the slight rise in teen pregnancy in 2006.
