Anal sex role patterns and correlates during unprotected anal sex were examined longitudinally among HIV-negative men who have sex with men. Nearly 9.6% were exclusively receptive, 16.7% exclusively insertive, and 63.0% versatile. Versatility was more likely with primary and HIV-negative/unknown status partners and among younger men and substance users but less likely among Blacks and with higher number of partners. Exclusively receptive role was more likely with HIV-negative/unknown status partners and among younger men and substance users but less likely with higher number of partners. Examining anal sex role patterns helps understand the factors that drive the epidemic among men who have sex with men.
本研究旨在探究男男性行为人群中无保护肛交时的肛交角色模式及其相关因素。研究发现，9.6%的参与者为单纯受动方，16.7%的参与者为单纯主动方，63.0%的参与者为两者兼而有之的混合方。与初次发生肛交关系的性伴、HIV 阴性/未知感染状态的性伴、年轻的性伴、以及使用药物的性伴中，混合方的比例较高，而与黑人性伴、与性伴发生肛交次数较多的性伴中，混合方的比例较低。单纯受动方与 HIV 阴性/未知感染状态的性伴、年轻的性伴、以及使用药物的性伴中比例较高，与性伴发生肛交次数较多的性伴中比例较低。本研究对肛交角色模式的分析有助于理解男男性行为人群中 HIV 流行的驱动因素。
