在美国，人类免疫缺陷病毒（HIV）感染率在与男性发生性关系的黑人男性（BMSM）中最高。先前的研究表明，特别是年轻的BMSM（即29岁及以下的BMSM）最容易感染艾滋病毒，并且近年来该亚人群的艾滋病毒发病率有所上升。然而，为什么年轻的男同性恋者比30岁及以上的男同性恋者感染艾滋病毒的风险更高，这一点尚不清楚。在目前的研究中，我们调查了450个位于亚特兰大，GA大都会和周边地区的BMSM。我们评估了BMSM的抑郁症状、性行为中的物质使用、社会心理风险因素（即艾滋病毒风险认知、避孕套使用自我效能、内化的同性恋恐惧症和感知的艾滋病毒污名化）和性风险承担（即无避孕套肛交[CAI]）。我们发现年轻的BMSM （YBMSM）和年长的BMSM （OBMSM）在与CAI相关的因素方面存在差异。在多变量模型中，性行为前或性行为中的酒精使用、较低的受教育程度和性取向（即双性恋性取向）与YBMSM的CAI增加显著相关，而HIV风险认知和内化同性恋恐惧症与mbsm的CAI显著负相关。参与CAI的比率在两个年龄组之间相似；然而，与CAI相关的因素在两组之间存在差异。研究结果强调需要考虑针对不同代际BMSM人群的针对性干预措施。
In the United States, rates of human immunodeficiency virus (HIV) infection are highest among Black men who have sex with men (BMSM). Prior research indicates that younger BMSM in particular (i.e., BMSM 29 years of age and younger) are most at risk for HIV infection and that HIV incidence in this subpopulation has risen in recent years. It remains unclear, however, why younger BMSM, relative to BMSM 30 years of age and older, are at increased risk for HIV infection. For the current study, we surveyed 450 BMSM located in the Atlanta, GA metropolitan and surrounding areas. We assessed BMSM’s depressive symptoms, substance use during sex, psychosocial risk factors (i.e., HIV risk perceptions, condom use self-efficacy, internalized homophobia, and perceived HIV stigmatization), and sexual risk taking (i.e., condomless anal intercourse [CAI]). We found that younger BMSM (YBMSM) and older BMSM (OBMSM) differed with respect to factors associated with CAI. In multivariable models, alcohol use before or during sex, lower educational attainment, and sexual orientation (i.e., bisexual sexual orientation) were significantly associated with increased CAI for YBMSM, while HIV risk perceptions and internalized homophobia were significantly, negatively associated with CAI among OBMSM. Rates of engaging in CAI were similar across the two age cohorts; however, factors related to CAI varied by these two groups. Findings emphasize the need to consider targeted interventions for different generational cohorts of BMSM.
