1 With the identification and rapid spread of HIV in the early 1980s among men who have sex with men, these commercial sex venues were quickly thought to be key factors in the epidemic 2– 4 and were soon the targets of government intervention. Gay bathhouses and sex clubs-2 key types of commercial sex venues catering exclusively to men-have operated in the United States since at least the first decade of the 20th century. Future research should evaluate the effect of structural and individual-level interventions on HIV transmission. Patron and venue-specific characteristics factors may each influence the frequency of HIV risk behaviors in commercial sex venues. The 20 survey populations did not differ significantly in demographics or behaviors.Ĭonclusions. Sex venue site and patron drug use were strongly associated with unprotected anal intercourse at the crude level. By logistic regression, recent unprotected anal intercourse outside of a commercial sex venue was independently associated with unprotected anal intercourse. Fourteen percent of respondents reported a previous HIV-positive test, 14% reported unprotected anal intercourse, and 9% reported unprotected anal intercourse with a partner of unknown or discordant HIV status during the current commercial sex venue visit.

We analyzed the 2004 data to identify patron characteristics and predictors of risk behaviors and compared the 2 survey populations. Surveys were anonymous and self-reported. We conducted cross-sectional, observational surveys in 20 by use of time–venue cluster sampling with probability proportional to size. We studied the HIV risk behaviors of patrons of the 3 commercial sex venues for men in Seattle, Washington.
