Illicit drug use among gay men is common and is associated with behaviours that are at high risk for HIV transmission.
We explored illicit drug use within an ongoing cohort study of gay men living with HIV in Sydney, Australia. Most (84.3%) of the 274 New South Wales participants interviewed in 2004 for the Positive Health Cohort of HIV-seropositive gay men had used illicit drugs in the 6 months before their baseline interview.
One in six men (17.8%) used 'party drugs' at least monthly. At 12 months' follow-up, in 2005, these patterns of illicit drug use were similar. Being younger, participating in gay 'party scenes' and engaging in 'esoteric sex practices' at baseline were associated with any and more frequent use of party drugs, both in 2004 and 2005. Illicit drug use was, however, not associated with condom use at the most recent sexual encounters.
Illicit drug use appears to be highly contextual among these gay men living with HIV, and the association with risk behaviour may reflect participation in sexually adventurous subcultures as much as a direct causal effect.
男同性恋者中使用非法药物的情况很常见，且与高风险的艾滋病毒传播行为有关。
在澳大利亚悉尼一项针对感染艾滋病毒的男同性恋者的队列研究中，我们探讨了非法药物的使用情况。2004年，参与新南威尔士州艾滋病毒血清阳性男同性恋者健康队列研究的274名参与者中，大部分（84.3%）在基线访谈前6个月内使用过非法药物。
六分之一的男性（17.8%）至少每月使用一次“派对药物”。在2005年12个月的随访中，这些非法药物使用模式相似。在2004年和2005年，基线时年龄较小、参与男同性恋“派对场景”以及进行“特殊性行为”与使用派对药物以及更频繁地使用派对药物有关。然而，在最近一次性接触中，非法药物使用与使用避孕套并无关联。
在这些感染艾滋病毒的男同性恋者中，非法药物使用似乎高度依赖具体情境，与风险行为的关联可能既反映了参与性冒险亚文化，也反映了直接的因果效应。
