摘要
目的了解南京市不同活动场所男男性行为者(MSM)行为特征及艾滋病、梅毒感染现状,为制定针对性干预措施提供依据。方法在知情同意的前提下,采用分类滚雪球法招募MSM,于2014—2015年在南京市3次开展问卷调查,并进行HIV、梅毒抗体血清学检测。结果共调查MSM 1 721人,其中酒吧型占11.04%,浴池型占6.74%,公园型占3.78%,网络型占70.42%、其他型占8.02%。不同场所MSM在年龄、婚姻状况、文化程度、性取向、艾滋病知识知晓率等方面的差异均有统计学意义(P值均<0.05)。多性伴比例为网络型(51.49%)最高;最近6个月与同性发生无保护性肛交比例、与异性发生无保护性行为比例和最近1年患有性病的比例均为公园型最高,分别为52.31%、27.69%、15.38%;商业性行为比例在公园型(10.20%)和酒吧型(9.46%)中略高。调查人群中HIV抗体阳性率为11.97%,梅毒抗体阳性率为7.84%,HIV感染率为浴池型(19.83%)最高,梅毒感染率为公园型(23.08%)最高,不同场所MSM的HIV和梅毒感染率差异有统计学意义(P值均<0.05)。结论南京市不同场所MSM人口学、行为学特征各异,HIV和梅毒感染率也存在差异,应根据各自特点制定更有针对性的干预措施。
Objective To understand the sexual behavior characteristics and current HIV/Syphilis infection status among MSM in different partner-seeking venues in Nanjing City; to provide basis for making targeted intervention measures. Methods Classification snowball sampling method was used to recruit MSM in Nanjing city under the principle of informed consent, who were subjected to 3 times of questionnaire based surveys and serological tests for HIV/syphilis. Results A total of 1 721 MSM were recruited and surveyed, of whom 11.04% were from bars,6.74% were from public bathrooms, 3.78% were from parks,70.42% were on the internet and 8.02% were from other places. The differences of age, marriage status, educational background, sexual orientation and the awareness rate of HIV knowledge among the 5 groups were all significant（all P〈0.05） . MSM on the internet had the highest proportion （51.49%） of multiple sexual partners. MSM from parks had highest rates of unprotect homose：（ual anal sexual intercourses （52.31% ）, heterosexual intercourses （27.69%） and sexually transmitted disease （STD） in past year（15.38%）. The MSM from parks （10.20%） and bars （9.46%） had relatively high proportion of commercial sexual intereourses. The HIV antibody positive rate was 11.97%, the syphilis antibody positive rate was 7.84% among all subjects. MSM from public bathrooms had highest HIV antibody positive rate （19.83 %） while MSM from parks had highest syphilis antibody positive rate （23.08%）. There were significant differences in HIV and syphilis infection rates among different MSM from different places（P〈0.05）. Conclusion The demographic and behavioral characteristics of MSM in different places in Nanjing are different; their HIV and syphilis infection rates are also different.
