中文摘要:
      目的 了解广州市MSM人群个体社会网络中关系强度及其相关因素。方法 2016-2017年在广州市13个艾滋病自愿咨询检测点,对前来参加艾滋病相关知识咨询以及HIV初筛的MSM人群进行个体社会网络问卷调查。采用横断面调查,样本量估计n=1 100。采用SAS 9.4软件进行χ2检验及广义估计方程模型分析相关因素。结果 招募1 073名调查对象,获得4 301名被提名者,强连带关系1 374对(30.67%)。年龄相似的MSM(OR=1.2,P=0.01)、通过线下交友方式认识(OR=1.65,P<0.01)的MSM更容易形成强连带关系;相对于MSM传统活动场所(棋牌室/茶室/浴池/会所),普通大众活动场所(酒吧/KTV/公园/校园/商场/餐厅)较易形成强连带关系(OR=1.46~3.12,P<0.01)。18~25岁MSM易与比自己年龄大的MSM形成弱连带,26~30、31~40、41~50岁的MSM均易与比自己年龄小的MSM形成弱连带。结论 MSM人群在不同年龄交往上具有一定的聚集性,MSM人群之间关系的强弱在交友方式以及交友场所分布上明显不同。通过识别不同亚人群特征、不同特征人群在交友方式、场所的分布差异,应探索创新型干预措施。
英文摘要:
      Objective To study the characteristics of social relations and relative factors among MSM in Guangzhou. Methods Data was collected through a cross-sectional study in Guangzhou from November 2016 to May 2017. Sample size was estimated and participants were recruited from the voluntary counseling and testing services (VCT) which were set for MSM population, by nongovernmental organizations (NGOs) and the Centers for Disease Control and Prevention (CDC). Social ties and demographic characteristics of the respondents and their sexual partners were analyzed through both Chi square test and generalized estimating equations (GEE). Results A total of 1 073 MSM, together with their nominated 4 301 partners were successfully recruited and involved in this study. Age (OR=1.2, P=0.01) and non-internet based intercourse (OR=1.65, P<0.01) were easy to form close relation with strong ties. Compared with MSM traditional venues (chess and cards room, tea room bathhouse, club), general public venue (bars, KTV, parks, shopping malls, schools, restaurants) (OR=1.46-3.12, P<0.01) showed close relation with strong ties. Our finding showed that MSM at the age of 18-25 preferred to build weak ties with the older MSM, while the 26-30-year-olds and 31-40-year-olds prefer to establish weak ties with younger partners but the 41-50-year-olds preferred to develop weak ties with one that were ten years younger. Conclusions Clusters were noticed in the MSM populations when grouping and making friends with ones at different age. Characteristics regarding the relationship between sexual partners in choosing venues and ways of dating were different. Targeted intervention programs need to be explored innovatively.
