title: Probability sample estimates of bathhouse sexual risk behavior.
abstract: OBJECTIVE
  Previous research links high rates of unprotected anal intercourse (UAI) with men who go to bathhouses; however, the literature provides no prevalence estimates. An exit survey of a probability sample was conducted to describe the prevalence of risk activity at the bathhouse.
  
  
  METHODS
  Data are from a 2-stage probability sample of men exiting a gay bathhouse (n = 400).
  
  
  RESULTS
  During their visit, 91.5% of men had oral sex and 44.2% had anal sex (11.1% reported UAI and 5.5% reported unprotected receptive anal intercourse). In the prior 3 months, 85% reported having anal sex, which was more likely to be unprotected when it occurred in a private home or hotel as opposed to a public setting (P < 0.001). Moreover, having UAI at home was a significant correlate of risk during the bathhouse visit (P < 0.001).
  
  
  CONCLUSIONS
  Most men at the bathhouse engaged in oral sex rather than anal sex, and most anal sex included use of condoms. Furthermore, men were more likely to have UAI in a private home than in any public setting. The bathhouse seems to have facilitated condom use when anal sex occurred on-site.
