2015年常德市男男性行为人群HIV感染情况及相关危险因素调查分析

Prevalence of HIV infection and related risk factors among MSM in Changde City

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 investigate the infection status of HIV and the related risk factors among men who have sex with men （MSM） in Changde City so as to provide evidence for implementing the effective prevention and control strategies. Methods An anonymous questionnaire survey was conducted among MSM based on the cooperation of MSM groups. Multivariate logistic regression model was used to analyze the risk factors of HIV infection. Results Five hundred MSM were surveyed, and the HIV infection rate was 2.8%. The awareness rate of HIV/AIDS knowledge was 87.7%. 63.8% of them had anal sex in the past 6 months, among which only 49.8% persistently used condoms. Multivariate logistic regression analysis showed that the older the MSM, the higher the HIV infection rate （for the age group of 30-59 years, OR=8.081; for the age group of 59- years,OR=14.252）. There was a positive correlation between suffering from venereal diseases and HIV infection （OR=17.641）. Conclusions The infection rate of HIV among the MSM in Changde City is low. The phenomenon of the separation between knowledge and action is prevailing. It is necessary to enhance the intervention and surveillance of high-risk behavior so as to restrict the spread of HIV/AIDS to the general population.
