目的了解常德市男男性行为人群艾滋病毒感染状况及相关危险因素,为实施有效防制策略提供依据。方法在MSM小组配合下,对常德市MSM人群进行匿名问卷调查,拟合多因素logistic回归模型探讨HIV感染的危险因素。结果调查500名MSM人群,HIV的感染率为2.8%。MSM人群艾滋病知识的知晓率为87.7%,但近6个月发生过肛交的MSM占63.8%,其中坚持使用安全套的仅49.8%。多因素logistic回归分析结果表明,年龄越大,MSM人群感染HIV的危险性越大(30~59岁组:OR=8.081;>59岁组:OR=14.252),患性病与感染HIV存在正相关关系(OR=17.641)。结论常德市MSM的HIV监测感染率较低,“知行分离”现象比较严重,今后需加强高危行为干预和监测力度,减少危险行为发生,加大发现力度,遏制艾滋病疫情向一般人群蔓延。
Objective To understand the HIV status and related risk factors among men who have sex with men (MSM) in Changde City, and to provide basis for effective prevention and control strategies. Methods With the help of MSM team, anonymous questionnaire was conducted in Changde MSM population, and multivariate logistic regression model was fitted to explore the risk factors of HIV infection. Results Investigating 500 MSM populations, the HIV infection rate was 2.8%. The awareness rate of HIV / AIDS among MSM population was 87.7%, but 63.8% of MSM had anal intercourse in the past 6 months, of which only 49.8% insisted condom use. Multivariate logistic regression analysis showed that the risk of HIV infection was higher in MSM population (30- 59 years old: OR = 8.081; OR> 59 years old: OR = 14.252) with age, and sexually transmitted diseases was positively correlated with HIV infection Relationship (OR = 17.641). Conclusion The prevalence of HIV infection in Changde MSM is relatively low, and the phenomenon of “separation of knowledge from practice” is more serious. In the future, it is necessary to strengthen the intervention and monitoring of high-risk behavior to reduce the occurrence of dangerous behaviors and intensify the detection so as to prevent the spread of AIDS epidemic to the general population.
