To assess the potential role of bisexual men in the transmission of HIV to women.
The study population consisted of homosexual men participating in a longitudinal cohort study on HIV and AIDS in Amsterdam, the Netherlands, which started in 1984. Between April and November 1991, an additional questionnaire was administered concerning sexual behavior with both male and female partners in the last 6 months.
Of these men, 27% described their sexual preference as bisexual or heterosexual. In the last 6 months, 23 (3%) had heterosexual contacts. Vaginal intercourse was the sexual technique most practiced. Anal intercourse with a female partner was rare. Four heterosexual active HIV positive men always used condoms when having heterosexual contact (1 missing). Of the 18 heterosexually active HIV seronegative men, 12 did not use condoms consistently with their female partner(s). Two of these 12 men also had unprotected insertive anogenital intercourse with male partners, which conveys a small transmission risk in the window period in the case of a seroconversion.
Widespread transmission of HIV from these homosexual men in this study is not likely. However, the studied men are most probably not representative for homosexual men in Amsterdam, the Netherlands. Further study on the potential role that bisexual men play in the HIV transmission to women is therefore needed.
评估双性恋男性在将艾滋病毒传播给女性方面的潜在作用。
研究人群包括参与荷兰阿姆斯特丹一项始于1984年的关于艾滋病毒和艾滋病的纵向队列研究的同性恋男性。1991年4月至11月期间，针对过去6个月与男性和女性伴侣的性行为发放了一份补充问卷。
在这些男性中，27%将他们的性取向描述为双性恋或异性恋。在过去6个月里，23人（3%）有异性性接触。阴道性交是最常进行的性行为方式。与女性伴侣进行肛交的情况很少见。4名有异性性接触的艾滋病毒阳性男性在进行异性性接触时总是使用避孕套（1人情况不明）。在18名有异性性接触的艾滋病毒血清阴性男性中，12人与其女性伴侣并非始终使用避孕套。这12名男性中有2人还与男性伴侣进行了无保护的插入式肛门生殖器性交，在血清转化的窗口期这会带来较小的传播风险。
在本研究中，这些同性恋男性不太可能导致艾滋病毒的广泛传播。然而，所研究的男性很可能不代表荷兰阿姆斯特丹的同性恋男性。因此，需要进一步研究双性恋男性在艾滋病毒传播给女性方面所起的潜在作用。
