Viagra, Methamphetamine and HIV Risk: Results From a Probability Sample of MSM, San Francisco
October 3, 2007
The authors undertook the current study to evaluate the prevalence and factors of Viagra use in combination with crystal methamphetamine and its relationship to HIV risk behavior in a probability sample of men who have sex with men (MSM). They conducted a cross-sectional, random-digit dial telephone survey of San Francisco MSM between June 2002 and January 2003.
Of the 1,976 MSM polled, 13.5 percent used Viagra alone; 5.1 used Viagra with methamphetamine; 7.1 percent used methamphetamine without Viagra; and 9.6 percent used Viagra with a mood-altering substance other than methamphetamine. Of the MSM who reported using both Viagra and methamphetamine, 57 percent were HIV-positive, and 24 percent of these MSM reported serodiscordant unprotected insertive intercourse. Use of Viagra with methamphetamine was independently associated with a higher risk of serodiscordant unprotected insertive intercourse, serodiscordant unprotected receptive intercourse, and recent STD diagnosis.
"MSM who use Viagra with crystal methamphetamine have high prevalence rates of HIV and engage in HIV risk behaviors," the authors concluded.
