Unprotected anal intercourse among men-who-have-sex-with-men (MSM) occurs more frequently between partners in a primary relationship than between nonprimary partners. Although research supports the role of social support in risky sex, findings also suggest that the reasons associated with risky sex differ depending on both the relationship status and HIV-serostatus of MSM. This study assessed whether level of intimacy within a primary relationship helps to explain risky sex among a sample of 78 HIV-positive MSM currently involved in a primary relationship. Findings suggest that both drug use prior to sex and HIV status of the primary partner moderate the relationship between intimacy and sexual risk behaviors. Under levels of low drug use, greater intimacy functioned as a protective factor within seroconcordant relationships whereas it functioned as a risk factor within serodiscordant relationships. Implications for educational and clinical interventions are discussed.
男男性行为者（MSM）中，无保护肛交在主要关系伴侣间比在非主要关系伴侣间更频繁发生。尽管研究支持社会支持在危险性行为中的作用，但研究结果也表明，与危险性行为相关的原因因MSM的关系状况和HIV血清学状态而异。本研究评估了主要关系中的亲密程度是否有助于解释78名目前处于主要关系中的HIV阳性MSM样本中的危险性行为。研究结果表明，性行为前的药物使用和主要伴侣的HIV状态均调节了亲密程度与性风险行为之间的关系。在低药物使用水平下，更高的亲密程度在血清学一致的关系中起到保护因素的作用，而在血清学不一致的关系中则起到风险因素的作用。文中讨论了对教育和临床干预的启示。
