内蒙古自治区2018—2022年青年MSM人群HIV监测结果分析

Analysis of HIV monitoring results in the youth MSM population of Inner Mongolia Autonomous Region from 2018 to 2022

目的对内蒙古自治区2018—2022年男男性性行为者(men who have sex with men,MSM)哨点监测中的青年人群数据进行分析,了解该高危人群的人类免疫缺陷病毒(Human immunodeficiency virus,HIV)感染状况和“知行”特征,为调整青年男男性性行为(youth men who have sex with men,YMSM)人群艾滋病防治策略提供参考依据。方法对内蒙古自治区2018—2022年YMSM人群进行面对面的问卷调查。率的变化趋势使用χ^(2)趋势检验,使用logistic回归分析对影响HIV感染的影响因素进行检验。结果2018—2022年共调查YMSM人群553人,民族构成比差异无统计学意义(χ_(趋势)^(2)=0.34,P=0.56);婚姻状态构成比差异无统计学意义(χ_(趋势)^(2)=0.07,P=0.79);以大专及以上文化程度为主,文化程度构成比差异有统计学意义(χ_(趋势)^(2)=4.27,P=0.04)。共检出HIV抗体阳性29例,阳性率为5.24%,阳性率差异无统计学意义(χ_(趋势)^(2)=3.05,P=0.08)。YMSM人群HIV知识知晓率为97.11%,知晓率差异无统计学意义(χ_(趋势)^(2)=3.06,P=0.08)。logistic回归分析结果显示,艾滋病知晓情况与HIV检测结果呈负相关(OR=0.06,P<0.01)。结论目前内蒙古自治区YMSM人群HIV阳性率呈逐年下降趋势,为持续减少YMSM人群新发感染,应在继续提高知晓率的同时,持续推动YMSM人群艾滋病防治知行合一。

Objective To analyze data pertaining to youth men who have sex with men(MSM)from the sentinel surveillance of MSM in Inner Mongolia Autonomous Region between 2018 and 2022,and to comprehend the Human immunodeficiency virus(HIV)infection status and"knowledge and practice"characteristics of this high-risk population,so as to provide a reference basis for adjusting acquired immunodeficiency syndrome prevention and control strategies for youth men who have sex with men(YMSM).Methods A face-to-face questionnaire survey was conducted on the YMSM population in Inner Mongolia Autonomous Region from 2018 to 2022.The rate′s trend was examined using theχ_(trend)^(2) test,and logistic regression analysis was employed to inspect the influencing factors of HIV infection.Results Between 2018 and 2022,a total of 553 YMSM population were surveyed.There was no statistically significant difference in ethnic proportion(χ_(trend)^(2)=0.34,P=0.56);likewise,the differences in marital status composition showed no statistically significant(χ_(trend)^(2)=0.07,P=0.79).However,with a prevalent educational level of college and mainly above,the differences in educational level composition were statistically significant(χ_(trend)^(2)=4.27,P=0.04).HIV antibody positivity was detected in 29 cases,yielding a positive rate of 5.24%,the difference was not statistically significant(χ_(trend)^(2)=3.05,P=0.08).The HIV knowledge awareness rate among the YMSM population was 97.11%,the difference was not statistically significant(χ_(trend)^(2)=3.06,P=0.08).The results of logistic regression analysis revealed a negative correlation between AIDS knowledge and HIV test results(OR=0.06,P<0.01).Conclusion Currently,the HIV positive rate among the YMSM population in Inner Mongolia Autonomous Region demonstrates a declining trend from year to year.To consistently reduce new infections in the YMSM population there is a need to concurrently improve the awareness rate and advocate for the integration of AIDS prevention and control knowledge and action in the YMSM population.
