This paper describes the sexual risk practices of 322 HIV-positive gay and bisexual men who reported having unprotected anal, oral or vaginal sex with an HIV-negative or unknown status partner(s) during the previous four months. Descriptive data on type of sex, partner types and number of partners are presented. Determinants of unprotected anal and oral intercourse were examined using a social cognitive framework. More unprotected anal sex was associated with having a steady versus a casual partner, not being on triple drug therapy, increased use of drugs and alcohol, and lower outcome expectancies for condom use and negotiation of safer sex practices. Unprotected oral sex was associated with partner type; men with casual partners had less unprotected oral sex as compared to men with steady partners. Findings are discussed in relation to the development of sexual risk reduction interventions for HIV-positive individuals.
本文描述了322名艾滋病毒呈阳性的男同性恋者和双性恋者的性风险行为，这些人报告称在过去四个月内与艾滋病毒呈阴性或状况不明的伴侣进行了无保护的肛交、口交或阴道性交。文中呈现了关于性行为类型、伴侣类型及伴侣数量的描述性数据。使用社会认知框架对无保护肛交和口交的决定因素进行了研究。更多的无保护肛交与拥有固定伴侣而非临时伴侣、未接受三联药物治疗、药物和酒精使用增加以及对使用避孕套和协商更安全性行为的结果期望较低有关。无保护口交与伴侣类型有关；与拥有固定伴侣的男性相比，拥有临时伴侣的男性进行无保护口交的情况较少。结合针对艾滋病毒呈阳性个体的性风险降低干预措施的开展对研究结果进行了讨论。
