As HIV infection rates remain high among young gay and bisexual men, investigations into determinants of sexual risk are paramount. This study examined independent and interactive effects of substance use, mental health, perceived benefits of unprotected sex, and type of sex partner on odds of not using condoms. Analyses included 188 high-risk substance using HIV-negative and unknown status young gay and bisexual men (ages 18-29). Substance use and endorsing favorable attitudes towards unprotected sex strongly predicted sexual risk. Mental health moderated the relationship between partner type (main vs. casual) and condom use such that increased anxiety and depression were associated with increased odds of using condoms with main partners and not using condoms with casual partners. Understanding how these determinants of HIV risk converge to predict unprotected anal sex can identify essential risk relationships for prevention, obtain effects sizes of greater magnitude and prolonged sustainability, and build robust couples-based interventions.
由于年轻的男同性恋和双性恋者中艾滋病毒感染率仍然很高,因此对性风险决定因素的研究至关重要。本研究调查了物质使用、心理健康、对无保护性行为的好处的认知,以及性伴侣的类型对不使用安全套的几率的独立和交互影响。分析包括 188 名高危物质使用的 HIV 阴性和未知状况的年轻男同性恋和双性恋者(年龄在 18-29 岁之间)。物质使用和对无保护性行为的赞成态度强烈预测了性风险。心理健康调节了伴侣类型(主要伴侣与偶然伴侣)和使用安全套之间的关系,即焦虑和抑郁的增加与与主要伴侣使用安全套和与偶然伴侣不使用安全套的几率增加有关。了解这些 HIV 风险决定因素如何汇聚以预测无保护的肛交,可以确定预防的基本风险关系,获得更大和更持久的效果大小,并建立强大的基于伴侣的干预措施。
