BACKGROUND
Anal sex is an important yet little studied HIV risk behavior for women.
METHODS
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.
RESULTS
Anal sex was nearly 3 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.
CONCLUSIONS
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.
背景
肛交是女性中一个重要但研究甚少的艾滋病毒感染风险行为。
方法
我们利用最近性接触中收集的信息，研究了性伴侣和关系特征对感染艾滋病毒风险较高的女性进行肛交的可能性的影响。
结果
活跃的双性恋女性中肛交的发生率几乎高出三倍（OR=2.96，95%CI：2.17-4.03）。与注射毒品的性伴侣（OR=2.32，95%CI：1.44-3.75）、非异性恋（OR=1.85，95%CI：1.18-2.90）以及与他们进行性交易以换取金钱或毒品的性伴侣发生肛交的可能性更大。与伴侣同睡的夜晚数越多，发生肛交的可能性也越大（OR=1.15，95%CI：1.06-1.24）。相比之下，情感亲近和社会亲近与肛交无关。肛交时使用安全套并不常见，且与伴侣或关系特征无关。
结论
我们的研究结果支持针对异性恋人群进行艾滋病毒预防干预的必要性，特别是在居住在艾滋病毒流行率较高的社区中的吸毒人群中。
