Abstract：
To investigate the prevalence of male circumcision and the willingness to undergo male circumcision and influencing factors among MSM in Maanshan City, we conducted a cross-sectional study from June 2016 to December 2019. Respondent-driven sampling (RDS) was used to recruit participants. Influential factors of willingness to accept circumcision were identified by a multivariable logistic regression model. The multivariable logistic regression model revealed that five variables were independent influential factors for willingness to participate. The factors include that used condoms during last anal intercourse (OR = 1.87, 95% CI:1.03-3.41, P = 0.04), sex with female sex partners (OR = 0.499, 95% CI:0.298-0.860, P = 0.012, level of education (junior college: OR = 0.413, 95% CI:0.200-0.854, P = 0.017; bachelor\'s degree or higher: OR = 0.442, 95% CI:0.208-0.938, P = 0.033), condom use during oral sex in the last six months (OR = 4.20, 95% CI:1.47-12.0, P = 0.007) and level of knowledge of PrEP (OR = 5.09, 95% CI:1.39-18.7, P = 0.014). Given the willingness of MSM to accept circumcision was low in China, establishing a proper understanding of circumcision is essential if it is to be used as a strategy to prevent HIV infection among MSM. Therefore, publicity and education on the operation should be strengthened to increase the willingness to undergo male circumcision.
摘要：
调查马鞍山市男性男性包皮环切术的患病率和接受包皮环切术的意愿及其影响因素。我们于2016年6月至2019年12月进行了一项横断面研究.采用受访者驱动抽样(RDS)招募参与者。采用多变量logistic回归模型确定接受包皮环切术意愿的影响因素。多变量logistic回归模型显示,5个变量是参与意愿的独立影响因素。影响因素包括在最后一次肛交期间使用避孕套（OR=1.87，95％CI：1.03-3.41，P=0.04），与女性性伴侣发生性关系（OR=0.499，95％CI：0.298-0.860，P=0.012，文化程度（大专：OR=0.413，95％CI：0.200-0.854，P=0.017；本科及以上学历：OR=0.442，95％CI：0.208-0.938，P=0.033），过去6个月口交期间使用安全套(OR=4.20,95%CI:1.47-12.0,P=0.007)和PrEP知识水平(OR=5.09,95%CI:1.39-18.7,P=0.014)。鉴于MSM在中国接受包皮环切术的意愿很低，如果要将包皮环切术用作预防MSM中HIV感染的策略，那么建立对包皮环切术的正确认识至关重要。因此,应加强对手术的宣传教育，以增加接受男性包皮环切术的意愿。
