作者调查了1988-1989年在艾滋病中心接受检测的2,314名男同性恋和双性恋者的性行为、人类免疫缺陷病毒1型（HIV-1）血清阳性率和安全套使用情况。在墨西哥城的国家中心，双性恋者占样本的24%，双性恋者的血清阳性率低于同性恋者（21 vs 34%）在logistic回归分析中，HIV-1血清阳性与年龄、教育程度、肛交中插入/接受行为模式、男性性伴侣的终生数量、与艾滋病患者发生性关系，同性恋与双性恋行为，双性恋者和同性恋者也符合同样的逻辑回归分析。在那些表示在进行接受性肛交时总是要求伴侣使用安全套的人中，HIV-1感染率降低。（占总数的1%）同性恋者和双性恋者最常见的做法是“混合”行为（即，插入和接受肛交）;这也是风险最高的行为。双性恋者与女性进行阴道和肛交，很少使用避孕套。双性恋者中的大量血清阳性率，他们与女性的频繁性接触，他们的避孕套使用率低，这意味着他们继续扮演着感染女性的桥梁角色，这种风险是否会导致持续的异性恋流行病，美国流行病学杂志1992，135 883-94。
The authors examined sexual behaviors, the seroprevalence of human immunodeficiency virus type 1 (HIV-1), and condom use among 2,314 homosexual and bisexual men tested during 1988-1989 at the AIDS (acquired immunodeficiency syndrome) National Center in Mexico City Bisexuals constituted 24% of the sample, the seroprevalence rate was lower for bisexuals than homosexuals (21 vs 34%) In logistic regressions, HIV-1 seropositivity was independently related to age, education, pattern of insertive/receptive behavior in anal sex, lifetime number of male sex partners, having sex with someone with AIDS, homosexual versus bisexual behavior, and a history of condyloma The same logistic regressions were found to fit bisexuals and homosexuals The rate of HIV-1 was reduced in individuals who indicated always requiring their partners to use a condom when practicing receptive anal sex (1% of the total) The most common practice for both homosexuals and bisexuals was “mixed” behavior (i.e., both insertive and receptive anal sex); this was also the practice with the highest risk Bisexuals practiced both vaginal and anal sex with women and reported little condom use The substantial seroprevalence among bisexuals, their frequent sexual contact with women, and their low rate of condom use imply a continuing role as a bridge of infection to females Whether this risk will lead to a sustained heterosexual epidemic remains to be determined.Am J Epidemiol1992,135 883–94.
