Abstinence-only not working

As reported in this week's issue of the British Medical Journal, Dr. Kristen Underhill and colleagues, from the University of Oxford in the UK, searched 30 electronic databases to identify studies that examined the effectiveness of abstinence-only programs as a means of preventing HIV infection. Data from 13 trials, containing nearly 16,000 U.S. youth, were included in their analysis.

Compared with no program, safer sex programs, and various other control programs, the abstinence-only programs did not seem to reduce HIV risk. Specifically, abstinence-only programs did not influence the rate of unprotected vaginal sex, the number of sexual partners, condom use, or initiation of sexual activity.

I don't know about their methodology, but honestly, I don't find this result surprising at all.
