目的评价艾滋病病毒(HIV)检测咨询,对男男性行为人群(Men who have sex with men,MSM)艾滋病相关危险行为变化的影响。方法通过问卷调查,收集廊坊市200名MSM参加HIV检测咨询前后高危行为的变化,并进行艾滋病和主要性病的检查,比较艾滋病相关危险行为的变化。结果 200名MSM基线调查HIV抗体阳性率为7.3%,梅毒感染率为19.8%,淋球菌检出率为15.8%;三个月后的随访调查中,梅毒感染率为24.7%,淋球菌感染率为12.2%。随访调查中MSM中多性伴的比例、发生一夜情的比例、肛交以及性交中自己出血的比例,均有所下降(P<0.05)。按照性病感染状态分层后发现,感染了性病的MSM,被告知检测结果后,发生肛交的比例由73%下降到38%(P<0.01),群交和性交过程中的出血情况分别由19.2%和23.1%下降到5.8%和5.8%(P<0.05)。未感染性病的MSM,一夜情的比例从32.5%下降到17.2%(P=0.008),口交比例由57.0%上升到78.5%(P=0.001)。感染了性病的MSM发生肛交的比例要低于健康MSM(χ2=5.189,P=0.023)。结论 HIV检测咨询对MSM艾滋病相关危险行为的改变有积极意义,建议在该人群中推广HIV检测咨询服务,促进高危行为的改变。
Objective To evaluate the impact of HIV testing counseling on HIV-related risk behaviors in men who have sex with men (MSM). Methods A questionnaire survey was conducted in 200 MSMs in Langfang City to investigate the changes of high-risk behaviors before and after HIV testing and counseling. HIV / AIDS and major STDs were examined to compare changes in HIV-related risk behaviors. Results The positive rate of HIV antibody in the 200 MSM was 7.3%, the infection rate of syphilis was 19.8% and the rate of Neisseria gonorrhoeae was 15.8%. In the follow-up survey three months later, the syphilis infection rate was 24.7% 12.2%. Follow-up survey MSM in the proportion of multiple sexual partners, the incidence of one-night stand, anal intercourse and sexual intercourse in their proportion of bleeding, have decreased (P <0.05). Stratification according to the state of STD infection found that MSM infected with STD was found to be reduced from 73% to 38% (P <0.01) after being notified of the test result. The bleeding rate during group and sexual intercourse was 19.2% And 23.1% to 5.8% and 5.8%, respectively (P <0.05). In MSM without STD, the rate of one-night stand decreased from 32.5% to 17.2% (P = 0.008) and the oral sex ratio increased from 57.0% to 78.5% (P = 0.001). The incidence of anal sex in MSM infected with sexually transmitted diseases was lower than that in healthy MSM (χ2 = 5.189, P = 0.023). Conclusions HIV testing counseling is of positive significance to the change of HIV-related risk behaviors in MSM. It is suggested that HIV testing counseling should be promoted in this population to promote the change of high-risk behaviors.
