BACKGROUND
Homosexual and bisexual men with acquired immunodeficiency syndrome (AIDS) differ, and bisexual men play an important role in the sexual transmission of human immunodeficiency virus (HIV) to women.
METHODS
To describe AIDS in these groups, we examined AIDS cases reported nationally through June 1990.
RESULTS
Among 65 389 men who reported having had sex with men since 1977, 26% were bisexual. More Black (41%) and Hispanic men (31%) than White men (21%) reported bisexual behavior. Bisexual men were twice as likely to report intravenous drug use (20%) as were homosexual men (9%), regardless of race or ethnicity. Among 3555 women with heterosexually acquired AIDS, 11% reported sexual contact with a bisexual man and no other risk factor, although in some states approximately half reported such contact. In 1989, the AIDS rate due to sex with a bisexual man was three and five times higher among Hispanic and Black women, respectively, than among White women.
CONCLUSIONS
Differences between bisexual and homosexual men with AIDS and the relative importance of AIDS in women due to sexual contact with bisexual men should be considered in the development of HIV prevention programs.
背景
患有获得性免疫缺陷综合征（艾滋病）的男同性恋者和双性恋者存在差异，双性恋男性在人类免疫缺陷病毒（HIV）向女性的性传播中起着重要作用。
方法
为描述这些群体中的艾滋病情况，我们调查了截至1990年6月全国报告的艾滋病病例。
结果
在自1977年以来报告与男性发生过性行为的65389名男性中，26%为双性恋者。报告双性恋行为的黑人男性（41%）和西班牙裔男性（31%）多于白人男性（21%）。无论种族或族裔如何，双性恋男性报告静脉注射吸毒的可能性（20%）是同性恋男性（9%）的两倍。在3555名异性感染艾滋病的女性中，11%报告与双性恋男性有性接触且无其他危险因素，不过在一些州，约有一半的女性报告有此类接触。1989年，西班牙裔和黑人女性因与双性恋男性发生性行为导致的艾滋病发病率分别是白人女性的三倍和五倍。
结论
在制定HIV预防计划时，应考虑患有艾滋病的双性恋男性和同性恋男性之间的差异，以及双性恋男性性接触导致女性感染艾滋病的相对重要性。
