目的：描述一年内异性肛交活动，并确定异性肛交和肛交中使用避孕套的相关因素。方法：对在3个公共性传播疾病（STD）诊所进行的一项试验资料进行二次分析。在这一年中，患者每3个月描述一次性行为。采用具有广义估计方程的逻辑回归模型来包括每个受试者的多个观测值。结果：2,357名异性恋对象报告了6611个3个月的间隔，其中包括9235个伴侣关系。约18.3%的受试者在特定的3个月间隔有肛交，39.3%的受试者在一年内有肛交。约23.5%的受试者在一年中至少有两次3个月间隔的肛交。肛交与多个性行为、2个或更多性伴侣、无保护的阴道性交和主要伴侣有关。在过去3个月的肛交中，27.3%的受试者一直使用避孕套，63%的受试者从未使用避孕套。持续使用避孕套进行肛交与持续使用避孕套进行阴道性交、2个或2个以上的伴侣以及与偶然性或新伴侣进行肛交相关。结论：性病门诊患者普遍存在异性肛交行为，且肛交时多数未使用安全套。肛交的患者也倾向于从事其他危险行为，使他们有感染性病/人类免疫缺陷病毒的风险。临床医生应该询问肛交，对肛交患者进行适当的检查和测试，并建议在肛交和阴道性交时使用避孕套。
Objectives: To describe heterosexual anal sex activity during a year and to identify factors associated with heterosexual anal sex and condom use during anal sex.Methods: Secondary analysis of data from a trial conducted in 3 public sexually transmitted disease (STD) clinics. Patients described sexual behaviors every 3-months for the year. Logistic regression models with generalized estimating equations were used to include multiple observations for each subject.Results: Two thousand three hundred fifty-seven heterosexual subjects reported on 6611 3-month intervals that included 9235 partnerships. About 18.3% of subjects had anal sex in a particular 3-month interval and 39.3% in the year. About 23.5% of subjects had anal sex in at least two 3-month intervals in the year. Anal sex was associated with having more sex acts, 2 or more sex partners, unprotected vaginal sex, and a main partner. For anal sex in the past 3 months, 27.3% of subjects consistently used condoms, and 63% of subjects never used condoms. Consistent condom use for anal sex was associated with having consistent condom use for vaginal sex, 2 or more partners, and anal sex with casual or new partner.Conclusion: STD clinic patients were commonly engaged in heterosexual anal sex, and most of them never used condoms during anal sex. Patients who had anal sex tended to also engage in other risk behaviors that put them at risk of STD/human immunodeficiency virus. Clinicians should ask about anal sex, appropriately examine and test patients who have had anal sex, and recommend condom use for both anal and vaginal sex.
