An understanding of men's motivations to avoid risk behavior is needed to create efficacious HIV prevention programs for HIV-positive men who have sex with men (MSM). This study investigates the relationship between sexual risk behavior and HIV prevention altruism, which is defined as the values, motivations, and practices of caretaking towards one's sexual partners to prevent the transmission of HIV. In a sample of 637 HIV-positive MSM, HIV prevention altruism significantly protects against serodiscordant unprotected anal intercourse (SDUAI) in crude analysis, but not after adjustment for drug use and compulsive sexual behavior. HIV prevention altruism is also related to not engaging in anal intercourse, but is not related to serodisclosure to secondary partners. Lack of altruism appears related to sexual risk behavior in HIV-positive MSM, although other psychological and contextual factors play significant roles. The promotion of HIV prevention altruism may provide a formidable new direction for HIV prevention programs.
为了为男男性行为者（MSM）中的HIV阳性者制定有效的HIV预防项目，需要了解男性避免危险行为的动机。本研究调查了性风险行为与HIV预防利他主义之间的关系，HIV预防利他主义被定义为照顾性伴侣以防止HIV传播的价值观、动机和行为。在637名HIV阳性MSM的样本中，在粗分析中，HIV预防利他主义显著预防血清学不一致的无保护肛交（SDUAI），但在调整药物使用和强迫性行为后则不然。HIV预防利他主义也与不进行肛交有关，但与向二级伴侣透露血清学状况无关。尽管其他心理和背景因素也起着重要作用，但在HIV阳性MSM中，缺乏利他主义似乎与性风险行为有关。促进HIV预防利他主义可能为HIV预防项目提供一个强大的新方向。
