肛交是一种重要的但很少研究的女性艾滋病风险行为。利用收集到的最近的性接触信息，我们研究了性伴侣和关系特征对艾滋病毒感染高风险妇女进行肛交的可能性的影响。肛交在活跃的双性恋女性中几乎是三倍多（OR = 2.96，95%CI 2.17 - 4.03）。女性更可能与注射毒品（OR = 2.32，95%CI 1.44 - 3.75），非异性恋（OR = 1.85，95%CI 1.18 - 2.90）和与他们交换金钱或毒品进行性行为（OR = 1.79，95%CI 1.10 - 2.90）的伴侣发生肛交。肛交的可能性也随着一起睡觉的夜晚数量而增加（OR = 1.15，95%CI 1.06 - 1.24）。相比之下，情感亲密和社会亲密与肛交无关。肛交时使用避孕套并不常见，也不因伴侣或关系特征而异。我们的研究结果支持了针对异性恋者肛交的艾滋病毒预防干预措施的必要性，特别是在居住在艾滋病毒流行水平较高的社区的吸毒人群中。
Anal sex is an important yet little studied HIV risk behavior for women. Using information collected on recent sexual encounters, we examined the influence of sex partner and relationship characteristics on the likelihood of engaging in anal sex among women with a high risk of HIV infection. Anal sex was nearly three times more common among actively bisexual women (OR = 2.96, 95% CI 2.17 – 4.03). Women were more likely to have anal sex with partners who injected drugs (OR = 2.32, 95% CI 1.44 – 3.75), were not heterosexual (OR = 1.85, 95% CI 1.18 – 2.90), and with whom they exchanged money or drugs for sex (OR = 1.79, 95% CI 1.10 – 2.90). The likelihood of anal sex also increased with the number of nights sleeping together (OR = 1.15, 95% CI 1.06 – 1.24). In contrast, emotional closeness and social closeness were not associated with anal sex. Condom use during anal sex was uncommon, and did not vary according to partner or relationship characteristics. Our findings support the need for HIV prevention interventions that target anal sex among heterosexuals, particularly in drug-using populations residing in neighborhoods with elevated levels of HIV prevalence.
