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...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。展开更多
