Few studies have examined actor-partner effects about male couples' substance use with sex. Dyadic data from 361 male couples were used to examine these effects regarding engagement in condomless anal sex (CAS) by type of partner and substance. Couples with one or both partners reported using marijuana, amyl nitrates, party drugs, and/or stimulants with sex in their relationship was positively associated with them having had CAS. Actor-partner effects for stimulant use with sex with the main partner were associated with CAS with a casual MSM partner. Only an actor effect for stimulant use with sex with a casual MSM partner was associated with CAS with that partner type, and an actor effect for marijuana use with sex for both partner types was associated with CAS with both partner types. These findings illuminate the need for further inquiry about male couples' substance use with sex for HIV prevention.
很少有研究考察男性伴侣间物质使用与性行为的行为者-伴侣效应。来自361对男性伴侣的二元数据被用于按伴侣类型和物质类型考察这些效应与无保护肛交（CAS）行为之间的关系。一方或双方伴侣报告在性行为中使用大麻、亚硝酸戊酯、派对药物和/或兴奋剂的伴侣关系，与他们进行过无保护肛交呈正相关。与主要伴侣性行为时使用兴奋剂的行为者-伴侣效应，与和偶然结识的男男性行为者（MSM）伴侣进行无保护肛交有关。仅与偶然结识的MSM伴侣性行为时使用兴奋剂的行为者效应，与和该伴侣类型进行无保护肛交有关，而与两种伴侣类型性行为时使用大麻的行为者效应，与和两种伴侣类型进行无保护肛交都有关。这些发现表明有必要进一步探究男性伴侣间物质使用与性行为以预防艾滋病。
