This study analyzed event-level partnership data from a computer-assisted survey of 719 gay and bisexual men (GBM) enrolled in the Momentum Health Study to delineate potential linkages between anal sex roles and the so-called "sex drugs," i.e., erectile dysfunction drugs (EDD), poppers, and crystal methamphetamine. Univariable and multivariable analyses using generalized linear mixed models with logit link function with sexual encounters (n = 2514) as the unit of analysis tested four hypotheses: (1) EDD are significantly associated with insertive anal sex roles, (2) poppers are significantly associated with receptive anal sex, (3) both poppers and EDD are significantly associated with anal sexual versatility, and (4) crystal methamphetamine is significantly associated with all anal sex roles. Data for survey respondents and their sexual partners allowed testing these hypotheses for both anal sex partners in the same encounter. Multivariable results supported the first three hypotheses. Crystal methamphetamine was significantly associated with all anal sex roles in the univariable models, but not significant in any multivariable ones. Other multivariable significant variables included attending group sex events, venue where first met, and self-described sexual orientation. Results indicate that GBM sex-drug use behavior features rational decision-making strategies linked to anal sex roles. They also suggest that more research on anal sex roles, particularly versatility, is needed, and that sexual behavior research can benefit from partnership analysis.
本研究分析了来自“动力健康研究”中719名男同性恋者和双性恋男性（GBM）的计算机辅助调查的事件层面伙伴关系数据，以描绘肛交角色与所谓“性药”（即勃起功能障碍药物（EDD）、Poppers和冰毒）之间的潜在联系。使用广义线性混合模型和logit连接函数，以性接触（n = 2514）为分析单位进行单变量和多变量分析，检验了四个假设：（1）EDD与插入式肛交角色显著相关；（2）Poppers与接受式肛交显著相关；（3）Poppers和EDD均与肛交的性取向显著相关；（4）冰毒与所有肛交角色显著相关。调查对象及其性伴侣的数据允许对同一接触中的双方肛交伴侣检验这些假设。多变量结果支持前三个假设。在单变量模型中，冰毒与所有肛交角色显著相关，但在任何多变量模型中均不显著。其他多变量显著变量包括参加群交活动、初次见面的场所和自我描述的性取向。结果表明，GBM的性药使用行为具有与肛交角色相关的理性决策策略。研究还表明，需要对肛交角色，特别是性取向进行更多研究，并且性行为研究可以从伙伴关系分析中受益。
