摘　　要：目的了解HIV感染男男性行为者(men who have sex with men,MSM)双性性行为现状,分析其影响因素。方法通过2个社会组织招募调查对象,使用问卷星进行匿名问卷调查。分别采用χ^(2)和t检验对计数资料和计量资料进行组间比较,使用多因素logistic回归模型分析HIV感染MSM双性性行为的影响因素。结果751名HIV感染MSM完成了问卷调查,17.04%(128/751)报告近6个月有双性性行为。其中,59.38%(76/128)报告近6个月与异性发生无保护性行为,25.78%(33/128)报告近6个月与同性发生无保护性行为。调查对象中,24.63%(185/751)有抑郁症状,11.85%(89/751)有焦虑症状,艾滋病污名化感知总分为(44.14±6.44)分,74.43%(559/751)报告近6个月有物质使用,85.75%(644/751)报告近6个月同性性伴≥2个。多因素logistic回归结果显示,婚姻状态为在婚/同居(OR=51.637,95%CI:24.745~107.752)及性取向为双性恋/异性恋(OR=14.284,95%CI:6.886~29.626)的MSM近6个月发生双性性行为可能更高;文化程度为大专及以上(OR=0.375,95%CI:0.171~0.820)、污名化感知水平越高(OR=0.953,95%CI:0.909~0.999)及近6个月有物质使用(OR=0.204,95%CI:0.096~0.434)的MSM近6个月发生双性性行为可能更低(P<0.05)。结论HIV感染MSM近6个月双性性行为比例较高,且多数调查对象有多个同性性伴,但性行为中安全套使用比例较低,有较大的HIV/STDs传播风险,应采取针对性措施对该人群风险性行为进行干预。Objective To understand the prevalence of bisexual behaviors and its affecting factors among HIV-infected men who have sex with men(MSM).Methods Participants were recruited through 2 social organizations,and an anonymous questionnaire survey was conducted through the questionnaire star platform.χ^(2)test and t test were used to compare categorical and continuous data between the groups respectively.Multivariate logistic regression model was employed to analyze the factors affecting bisexual behaviors of HIV-infected MSM.Results Seven hundred and fifty-one HIV-infected MSM completed the questionnaire survey.17.04%(128/751)of the participants reported having bisexual behaviors in the past 6 months,among which 59.38%(76/128)reported having unprotected sex with heterosexual partners in the past 6 months,and 25.78%(33/128)reported having unprotected sex with homosexual partners in the past 6 months.Among the participants,24.63%(185/751)had depressive symptoms,and 11.85%(89/751)suffered from anxiety symptoms.The total score of AIDS stigma perception was(44.14±6.44).74.43%(559/751)of the participants reported having substances use in the past 6 months,and 85.75%(644/751)reported having≥2 homosexual partners.The results of multivariate logistic regression analysis indicated that MSM who were married/cohabited with their partners(OR=51.637,95%CI:24.745-107.752)and whose sexual orientation was bisexual/heterosexual(OR=14.284,95%CI:6.886-29.626)were more likely to have bisexual sex in the past 6 months,while MSM receiving college or higher levels of education(OR=0.375,95%CI:0.171-0.820),having high perceptions of HIV stigma(OR=0.953,95%CI:0.909-0.999)and with substances use in the past 6 months(OR=0.204,95%CI:0.096-0.434)were less likely to have bisexual sex in the past 6 months(P<0.05).Conclusion The prevalence of bisexual behaviors in the past 6 months was high among the HIV-infected MSM,and the majority of the participants reported having multiple male sex partners.However,the proportion of condom use during sex was
