【摘要】：目的了解南京市不同性角色男男性行为者(MSM)的行为特征及艾滋病病毒(HIV)、梅毒感染现状,为制定更有针对性的干预措施提供依据。方法在知情同意的前提下,采用分类滚雪球法招募MSM,开展问卷调查,收集人口学、行为学等信息,并进行HIV、梅毒抗体血清学检测。结果共调查MSM 2 377人,根据最近6个月肛交时的性角色分为三组:插入组800人(33.66%)、被插入组615人(25.87%)和双向组962人(40.47%),三组在平均年龄、文化程度、在婚比例、同性恋自我认同比例、艾滋病知识知晓率、第一次肛交年龄、最近6个月与同性肛交的频率、男性性伴总数、与同性商业性行为时安全套使用频率、与异性性行为频率方面,差异有统计学意义(P0.05)。三组梅毒感染率分别为7.63%、8.29%和6.55%,差异无统计学意义(χ~2=1.79,P=0.41);HIV感染率分别为7.00%、13.50%和13.62%,差异有统计学意义(χ~2=22.76,P0.05)。多因素Logistic回归分析结果显示,被插入组感染HIV的风险是插入组的1.98倍[95%可信区间(CI)∶1.38~2.85],双向组感染HIV的风险是插入组的2.13倍(95%CI∶1.53~2.97)。结论南京市不同性角色MSM具有不同的人口学、行为学特征,插入组、被插入组和双向组感染HIV的风险依次增高,应根据各自的特点制定更有针对性的干预措施。
[Abstract]:Objective to investigate the behavioral characteristics of MSM (MSM) with different sex roles and the status of HIV / AIDS and syphilis infection in Nanjing, so as to provide the basis for formulating more targeted intervention measures. The method of classified snowball was used to recruit MSMs, questionnaire survey was carried out, demography, behavior and other information were collected, and HIV and syphilis antibody serological tests were carried out. Results A total of 2 377 MSM patients were investigated. They were divided into three groups according to their sexual roles during anal sex in the last six months: the insertion group (800 persons), the inserted group (615 persons) and the two-way group (962 persons). The three groups were divided into three groups: average age, education level, marriage ratio, homosexual self-identity ratio, and awareness rate of AIDS knowledge. The age of first anal sex, the frequency of anal sex with the same sex in the last 6 months, the total number of male sexual partners, the frequency of condom use during commercial sex with the same sex, and the frequency of heterosexual sex, The infection rate of syphilis in the three groups was 7.637.29% and 6.55, respectively. There was no significant difference (蠂 ~ 21.79 ~ 0.41% and 13.62%, respectively), and the difference was statistically significant (蠂 ~ (22. 766) P 0.05%). The multivariate Logistic regression analysis showed that the infection rate of syphilis in the three groups was 7.00% and 13.62% respectively (蠂 ~ (22. 76) P 0.05). The results of multivariate Logistic regression analysis showed that the infection rate of syphilis in the three groups was higher than that in the control group (P < 0.05). The risk of HIV infection in the insertion group was 1.98 times as high as that in the insertion group [95% CI: 1.382.85], and the risk of HIV infection in the two-way group was 2.13 times as high as that in the insertion group. Conclusion MSM of different sex roles in Nanjing has different demographics, behavioral characteristics and insertion group. The risk of HIV infection in inserted group and bidirectional group increased in turn, and more targeted interventions should be made according to their characteristics.
