Self-concealment of MSM and related factors in Mianyang, Sichuan

目的 了解四川省绵阳市男男同性性行为者(MSM)的自我隐瞒现状,分析相关因素。方法 用滚雪球抽样方法和自我隐瞒量表(self-concealment scale,SCS)对2021年1—12月绵阳市MSM人员进行MSM自我隐瞒等匿名问卷调查和HIV抗体检测,采用t检验/方差分析、Pearson相关性和多元线性回归分析自我隐瞒的相关因素。结果 共收集有效问卷1 089份,自我隐瞒得分(27.6±8.0)分。HIV抗体阳性、阴性者自我隐瞒得分分别为(30.3±7.2)分、(27.3±7.8)分(t=1.888,P=0.059)。多因素分析结果显示,年龄(β=0.100,P=0.001)、文化程度大专及以上(β=1.627,P=0.003)、职业工人/农民/餐饮服务(β=1.572,P=0.046)、社区朋友人数>10(β=1.688,P=0.001)、主要以传统方式寻找性伴(β=1.655,P=0.035)、近6个月发生无保护肛交(β=1.701,P=0.008)与自我隐瞒得分成正相关;干部职员/经商等职业(β=-2.358,P=0.001)、本地居住时间>2年(β=-2.670,P<0.01)、近1年接受过同伴教育(β=-3.212,P<0.01)、近6个月发生多性伴(β=-1.406,P=0.003)与自我隐瞒得分成负相关。结论 MSM自我隐瞒程度较高,自我隐瞒与人口学、社会行为特征及高危性行为相关,应积极营造降低MSM自我隐瞒的社会环境和针对性开展行为干预。

Objective To understand the current status of self-concealment of men who have sex with men(MSM) in Mianyang of Sichuan province, and to analyze the related factors. Methods A snowball sampling method was used to recruit MSM and an anonymous questionnaire survey was conducted using self-concealment scale(SCS) in Mianyang city from January to December, 2021. HIV antibody was also tested. t-test/variance analysis(F), Pearson correlation and multiple linear regression were used to analyze the related factors of selfconcealment. Results A total of 1 089 valid questionnaires were obtained. The mean score of self-concealment was 27. 6±8. 0. It was 30. 3±7. 2 among MSM with positive HIV antibody and was 27. 3±7. 8 among those with negative antibody(t=1. 888, P=0. 059). Multivariate analysis showed that age(β=0. 100, P=0. 001), college or above degree(β=1. 627, P=0. 003), workers/farmers/catering service(β=1. 572, P=0. 046), having more than 10 community friends(β=1. 688, P=0. 001), seeking sexual partners using traditional ways(β=1. 655, P=0. 035) and having unprotected anal sex in recent 6 months(β=1. 701, P=0. 008) were positively correlated with self-concealment score, however, cadre/business men(β=-2. 358, P=0. 001), local residence of over 2 years(β=-2. 670, P<0. 01), receiving peer education in recent 12 months(β=-3. 212, P<0. 01) and having multiple sex partners in recent 6 months(β =-1. 406, P=0. 003) were negatively correlated with self-concealment score. Conclusion MSM tend to be self-concealed. Self-concealment is related to demographic characteristics, social behavior and high-risk sexual behaviors. Therefore, it is necessary to actively create a social environment to prevent the self-concealment of MSM and to carry out targeted behavioral intervention.
