Abstract:

目的分析山东省MSM单性性行为者（单性MSM）和双性性行为者（双性MSM）的特征及HIV感染相关因素，为艾滋病防治对策和干预措施提供依据。方法 2018年4-7月在山东省9个MSM哨点监测点，收集当地MSM特征、相关行为信息，采集血样做HIV和梅毒检测。结果共调查MSM 3 474人，年龄（31.66±9.01）岁，为已婚/同居者1 218人（35.06%），大专及以上文化程度1 755人（50.52%），同性恋和双性恋者分别为2 783人（80.11%）和494人（14.22%）；最近6个月与异性发生性行为有586人（16.87%）；吸毒行为有365人（10.51%）；HIV阳性率为2.99%（104/3 474），梅毒阳性率为2.76%（96/3 474）。多因素logistic回归分析结果显示，年龄≥ 35岁、山东省户籍、性取向为异性恋/双性恋/不确定者、最近6个月有商业性行为、最近6个月发生无保护肛交、较少通过互联网/交友软件寻找男性性伴、无吸毒行为的MSM中，双性MSM的比例更高。单性和双性MSM，在最近1周性伴数、最近6个月商业性行为使用安全套、HIV感染、梅毒感染、最近1年患性传播疾病史的差异无统计学意义（P>0.05）。MSM的HIV感染相关因素包括年龄≥ 45岁、外省户籍、通过浴池、公园/公厕或者互联网/交友软件寻找男性性伴、最近6个月无保护性肛交、有吸毒行为、梅毒感染。结论山东省MSM中，双性性行为比例较高，广泛存在危险性行为，存在较高HIV感染风险，应针对不同特征MSM加强监测和干预。

English Abstract:

Objective This study aimed to examine the demographic characteristics, HIV related knowledge and behavior, correlates of bisexual behavior and status of HIV infection among men who have sex with men only (MSMO) and men who have sex with both men and women (MSMW) in Shandong province. Methods According to the requirements from "National HIV/AIDS sentinel surveillance program", a cross-sectional survey was conducted to collect information on demographics, sexual and drug use behaviors, and HIV-related services among MSM in nine sentinel surveillance sites from April to July in 2018. Blood samples were drawn for serological tests on both HIV and syphilis antibodies. Results A total of 3 474 participants were included in this study. Related information on these participants would include:average age as (31.66±9.01) years; 35.06% (1 218) married or cohabiting with a woman, 50.52% (1 755) had college or higher education, 80.11% (2 783) self-identified as gays and 14.22% (494) self-identified as bisexual men,16.87% (586) ever having sex with woman in the past 6 months, 10.51% (365) ever using drugs. HIV and syphilis prevalence rates were 2.99% (104/3 474) and 2.76%(96/3 474). Through multivariable logistic models, MSMW were more likely to be ≥ 35 years of age, local residents, self-identified as heterosexual/bisexual/uncertain, ever having commercial sex with man but less likely to consistently use condoms in the past 6 months, less using internet/dating software to find male sex partners and less using drugs. There was no significant differences noticed in the following areas:number of sexual partners in the last week, condom use in the last six months with commercial sex partners, with HIV or syphilis infection and self-reported history of STD in the past year between MSMO and MSMW (P>0.05). HIV-infected MSM were more likely to have the following features, ≥ 45 years of age, non-local residents, finding male sex partners from the bothhouses, park/toilets or from the internet/dating software, also less likely to consistently use condoms in the past 6 months, using drugs or with syphilis infection. Conclusions High prevalence of bisexual behavior as well as higher risk of HIV infection were noticed among MSM in Shandong province. It is important to strengthen related surveillance and effective intervention programs for MSM with different characteristics in Shandong province.
