Participants at a sexual health clinic completed a survey with questions regarding sexual risk behavior and partner characteristics. Of 585 participants eligible for analysis, 124 reported generally having older male partners. These participants were significantly more likely to be HIV-infected (p < 0.001), have four or more sex partners as a "bottom" (p = 0.04), have concurrent partners (p = 0.01), and have partners suspected of having an sexually transmitted infection (p = 0.05) than participants without older partners. With analysis restricted to HIV- individuals, risk behaviors did not differ significantly between the groups. HIV- individuals with older partners may be at increased risk of HIV infection due to increased HIV prevalence among older sexual partners and not due to increased risk behaviors with these partners.
一家性健康诊所的参与者完成了一项关于性风险行为和性伴侣特征的问卷调查。在585名符合分析条件的参与者中,124人报告称其性伴侣通常为年龄较大的男性。与没有年龄较大性伴侣的参与者相比,这些参与者感染艾滋病毒的可能性显著更高(p<0.001),作为“受方”有四个或更多性伴侣的可能性更高(p=0.04),有同时性伴侣的可能性更高(p=0.01),以及其性伴侣被怀疑感染性传播感染的可能性更高(p=0.05)。在仅对未感染艾滋病毒的个体进行分析时,两组之间的风险行为没有显著差异。有年龄较大性伴侣的未感染艾滋病毒个体感染艾滋病毒的风险可能会增加,这是由于年龄较大的性伴侣中艾滋病毒感染率较高,而非与这些伴侣发生性行为的风险增加。
