Gn. Colfax et al., Drug use and sexual risk behavior among gay and bisexual men who attend circuit parties: A venue-based comparison, J ACQ IMM D, 28(4), 2001, pp. 373-379
Context: HIV risk behavior among urban gay/bisexual men has recently increa
sed. High-risk sexual activity and drug use may be particularly high during
circuit party (CP) weekends, during which gay/bisexual men congregate for
social activities and dancing.
Objectives: To compare prevalence of risk behaviors during CP weekends with
those during non-CP weekends.
Design: Cross-sectional study.
Participants: 295 gay/bisexual men from the San Francisco Bay Area.
Main Outcome Measures: Drug use and sexual risk behavior during a San Franc
isco CP weekend, a CP weekend held in another geographic area (distant week
ends), and two non-CP weekends.
Results: During their most recent distant CP weekend, 80% of participants u
sed methylenedioxymethamphetamine (ecstasy), 66% ketamine, 43% crystal meth
amphetamines, 29% gamma-hydroxybutyrate or gamma-butyrolactone (GHB/GBL), 1
4% sildenafil (Viagra), and 12% amyl nitrites (poppers) 53% used four or mo
re drugs. Drug use prevalence was greater during CP than non-CP weekends (p
< .001). Unprotected anal sex with partners of unknown or opposite HIV ser
ostatus was most prevalent during distant CP weekends, reported by 21% of H
IV-positive and 9% of HIV-negative participants. In multivariate analysis,
predictors of unprotected anal sex with opposite or unknown HIV serostatus
partners included being HIV-positive (odds ratio [OR], 3.2; 95% confidence
interval [CI], 1.4-7.5), and weekend use of crystal methamphetamines (OR 2.
4; 95% Cl, 1.1-4.9), sildenafil (OR, 3.8, 95% Cl, 2.0-7.3), and amyl nitrit
es (OR, 2.2; 95% Cl, 1.3-4.0).
Conclusions: Prevalence of high-risk activity during these weekends suggest
s significant potential for HIV transmission in this population. Public hea
lth programs in communities hosting Cps should aim to reduce rates of drug
use and sexual risk behavior among CP participants, especially HIV-positive
men.
