接受性无安全套肛交是已知的肛门直肠衣原体感染的危险因素，但仍不清楚口肛交是否也有影响。我们的目的是确定是否oroanal性行为（rimming），指法，或使用唾液作为肛门润滑剂的风险因素，肛门直肠衣原体的男性与男性发生性关系（MSM）。方法这项横断面研究进行了墨尔本性健康中心从2014年7月至2015年6月。研究人员收集的计算机辅助自我访谈数据包括人口统计数据、性伴侣数量和避孕套使用情况。我们增加了问题，接受缘，接受指法或阴茎浸渍，并使用合作伙伴的唾液作为肛门lubricate.Results共1691男男性接触者完成了问卷调查，并进行了肛门直肠衣原体检测。在单变量分析中，肛门直肠衣原体感染与使用伴侣的唾液作为润滑剂（比值比[OR] 1.97，95%置信区间[CI] 1.26-3.09），接受性镶边（OR 1.59; 95% CI 1.04-2.45）和接受性指法或浸渍（OR 1.90; 95% CI 1.06-3.43）相关。在多变量分析中，肛门直肠衣原体感染与这些性行为无关，在调整了性伴侣数量、HIV感染状况、已知的衣原体接触和避孕套使用情况后。然而，性行为之间的共线性可能掩盖了与肛门直肠衣原体的关联，进一步的分析表明，这些性行为和肛门直肠衣原体之间的弱关联。结论使用合作伙伴的唾液在接受肛交的做法，如镶边，指法，或阴茎浸渍肛门直肠衣原体在男男性接触者的弱危险因素。这与我们以前报道的发现形成对比，即唾液作为肛门润滑剂与肛门直肠淋病的关系更密切。
Background Receptive condomless anal sex is a known risk factor for anorectal chlamydia, but it remains unclear whether oroanal sex practices also contribute. We aimed to determine whether oroanal sex (rimming), fingering, or the use of saliva as anal lubricant are risk factors for anorectal chlamydia among men who have sex with men (MSM).Methods This cross-sectional study was conducted at Melbourne Sexual Health Centre from July 2014 to June 2015. Routinely collected computer-assisted self-interview data included demographics, number of sexual partners, and condom use. We added questions on receptive rimming, receptive fingering or penis dipping, and the use of a partner's saliva as anal lubricant.Results A total of 1691 MSM completed the questionnaire and tested for anorectal chlamydia. In univariable analyses, anorectal chlamydia was associated with using a partner's saliva as lubricant (odds ratio [OR] 1.97, 95% confidence interval [CI] 1.26-3.09), receptive rimming (OR 1.59; 95% CI 1.04-2.45), and receptive fingering or dipping (OR 1.90; 95% CI 1.06-3.43). In multivariable analysis, anorectal chlamydia was not associated with these sexual practices, after adjusting for number of sexual partners, HIV status, known contact with chlamydia, and condom use. However, collinearity between sexual practices likely obscured associations with anorectal chlamydia, and further analyses suggested weak associations between these sexual practices and anorectal chlamydia.Conclusions The use of a partner's saliva during receptive anal sex practices such as rimming, fingering, or penis dipping were weak risk factor for anorectal chlamydia in MSM. This contrasts with our previously reported findings that the use of saliva as anal lubricant is more strongly associated with anorectal gonorrhea.
