With young men who have sex with men (YMSM) continuing to be disproportionately affected by the HIV/AIDS epidemic in the U.S., secondary prevention efforts with this population take on increasing significance. We surveyed 200 HIV-positive YMSM (ages 16-24, 66% Black, 18% Latino, 7% White, 7% Multiracial/Other) recruited from 14 HIV primary care sites to examine associations of unprotected anal intercourse (UAI) and partner HIV status with endorsement of serosorting, sexual positioning, and viral load beliefs. Proportions of participants engaging in UAI one or more times during the past three months were consistent across type of UAI (insertive or receptive) and partner status. Belief that an undetectable viral load reduces infectiousness was significantly associated with insertive UAI (p < .05) and receptive UAI (p < .05) with HIV-negative or unknown status partners and receptive UAI with HIV-positive partners (p < .01). Endorsement of belief in serosorting was significantly associated with receptive UAI (p < .01) and insertive UAI (p < .05) with HIV-positive male partners. Implications for sexual behavior and risk reduction beliefs in this population are discussed.
在美国,男男性行为者(MSM)继续受到艾滋病毒/艾滋病流行的不成比例的影响,因此,针对这一人群的二级预防工作具有越来越重要的意义。我们调查了 200 名艾滋病毒阳性的男男性行为者(年龄 16-24 岁,66%为黑人,18%为拉丁裔,7%为白人,7%为多种族/其他),他们是从 14 个艾滋病毒初级保健点招募的,目的是研究无保护肛交(UAI)和伴侣艾滋病毒状况与血清分类、性体位和病毒载量信念的关系。在过去三个月中,有一次或多次 UAI 的参与者比例在不同类型的 UAI(插入性或接受性)和伴侣状况下是一致的。认为病毒载量无法检测会降低传染性的信念与插入性 UAI(p <.05)和与 HIV 阴性或未知状况的伴侣进行的接受性 UAI(p <.05)以及与 HIV 阳性伴侣进行的接受性 UAI(p <.01)显著相关。对血清分类信念的认可与与 HIV 阳性男性伴侣进行的接受性 UAI(p <.01)和插入性 UAI(p <.05)显著相关。讨论了这一人群的性行为和降低风险信念的意义。
