Crystal methamphetamine: A source of added sexual risk for Hispanic men who have sex with men?

ObjectivesTo determine whether use of crystal methamphetamine increases HIV risk behaviors beyond the risk associated with use of other recreational drugs among Hispanic men who have sex with men (HMSM).DesignWe compared the sexual behaviors and psychosocial characteristics of non-recreational drug users (non-users), recreational drug users who did not use crystal (non-crystal drug users), and recreational drug users who used crystal (crystal users).MethodsWe recruited 294 HMSM from Internet and 272 from community venues. Eligible men completed an ACASI to assess socio-demographic factors, drug use, sexual behaviors and psychosocial factors and received $50.ResultsIn the multivariate model, crystal users were more likely than non-crystal drug users to have lower Hispanicism, higher attachment to the gay community, and history of suicide attempts. Crystal users were not significantly different from non-crystal drug users in number of sex partners; however, differences in unprotected receptive anal sex approached significance.ConclusionsThe additional risk of crystal above that of other recreational drugs needs to be disentangled from those associated with poly-drug use. Our data suggest that it may depend on how one defines risky sexual behavior and is influenced by psychological, physiologic and social factors.
