Human immunodeficiency virus (HIV) disproportionately affects black women. Nearly two-thirds of all female HIV cases reported to the CDC are black, and HIV is the leading cause of death among black women aged 25 to 34 years. The greatest HIV transmission risk among black women is sexual intercourse with a man, although the role of bisexual men is not clear.
The CDC and collaborating partners conducted behavioral surveys at 7 historically black colleges and universities from January 2005 to April 2007.
Of the 2705 black female students aged 18 to 29 years who were surveyed, 2040 (75%) reported being sexually active in the previous 12 months and, among sexually active women, 291 (14%) reported having sex with a bisexual man in the previous 12 months. Women who reported sex with a bisexual man were more likely than women who did not to report having at least 2 sex partners in the previous 12 months, having male and female sex partners, not using a condom at last intercourse, being in a committed relationship, never or infrequently attending church, and believing they were at increased risk for HIV infection.
Heterosexually active black women who have engaged in sexual intercourse with bisexual men have a different HIV risk profile than other heterosexually active black women.
艾滋病毒（HIV）在黑人群体中发病率过高。全美疾病预防与控制中心（CDC）报告的所有女性 HIV 病例中，近三分之二为黑人，HIV 也是 25 至 34 岁黑人女性的首要致死原因。在黑人女性中，最大的 HIV 传播风险来自与男性的性接触，尽管双性恋男性的作用尚不明确。
CDC 与合作机构于 2005 年 1 月至 2007 年 4 月在 7 所历史上的黑人高校开展行为调查。
在接受调查的 2705 名 18 至 29 岁黑人女学生中，有 2040 名（75%）报告过去 12 个月有过性行为，在有过性行为的女性中，有 291 名（14%）报告过去 12 个月与双性恋男性发生过性行为。报告与双性恋男性发生过性行为的女性比没有报告过的更有可能报告过去 12 个月有至少 2 个性伴侣、有男性和女性性伴侣、上次性行为未使用安全套、处于稳定的恋爱关系、从不或很少去教堂、并认为自己感染 HIV 的风险增加。
与双性恋男性发生过性行为的异性恋黑人女性，其 HIV 风险状况与其他异性恋黑人女性不同。
