分析的目的是检查甲基苯丙胺和其他俱乐部毒品的使用与同性恋和双性恋男性群体的性风险之间的关系。数据是从基于社区的样本中收集的。与随意伴侣进行无保护肛交的评估，以及甲基苯丙胺和其他非法药物的使用，在基线和一年中每隔4个月进行评估，并使用分层线性模型进行分析。甲基苯丙胺的使用与无保护的插入性和接受性性交的频率有关，无论是与艾滋病毒阳性的还是与身份不明的随意伴侣。甲基苯丙胺使用与无保护行为之间的联系在艾滋病毒阳性参与者中也更为明显。这些发现表明，甲基苯丙胺和无保护肛交是同时发生的危险行为，可能会增加同性恋和双性恋男性传播艾滋病毒的风险。艾滋病毒预防和干预应同时针对这两种行为。
The purpose of the analyses was to examine the associations between methamphetamine and other club drug use with sexual risk taking across time in cohort of gay and bisexual men. Data were collected from a community-based sample. Assessments of unprotected anal intercourse with casual partners, and use of methamphetamine and other illicit drugs, were assessed at baseline, and at 4-month intervals over the course of a year, and were analyzed using hierarchical linear modeling. Methamphetamine use was related to the frequency of unprotected insertive and receptive intercourse with both HIV-positive and status unknown casual partners across time. The association between methamphetamine use and unprotected acts also was more pronounced for HIV-positive participants. These findings suggest that methamphetamine, and unprotected anal intercourse are co-occurring risk behaviors, that potentially heighten the risk of HIV transmission among gay and bisexual men. HIV prevention and intervention should concurrently target both these behaviors.
