目的了解成都市艾滋病自愿咨询检测(VCT)门诊男男性行为者(MSM)人群特征、HIV感染状况,以便有效地在VCT门诊中开展男男性行为者人群的咨询检测及干预。方法对2014年成都市VCT门诊中接受咨询检测服务的MSM人群登记资料进行分析,描述性分析MSM人群特征,采用非条件logistic回归分析不同人口学特征的HIV感染风险。结果接受VCT服务的1 459名MSM中30岁以下占67.77%,未婚者占66.88%,大专及以上占51.66%;检出HIV抗体阳性率12.16%。多因素分析显示,相对于婚姻状况已婚者,离异或丧偶感染HIV风险更高(OR=9.088),其次为未婚者(OR=2.104);年龄组和婚姻状况存在感染HIV交互作用,30岁及以上且未婚者感染HIV风险更高(OR=2.106);既往接受检测者感染率高于未接受过检测者(OR=1.539);梅毒感染者感染HIV风险高于未感染梅毒者(OR=5.818)。结论成都市VCT门诊的MSM人群HIV阳性检出率相对较高;不同特征的MSM的感染风险不同,应有针对性地开展咨询检测及干预服务。
Objective To understand the population characteristics of MSM and the prevalence of HIV infection in VCT outpatient clinics in Chengdu in order to effectively conduct counseling and intervention in men with MSM in VCT clinics. Methods The registration data of MSM population who received counseling and testing service in VCT clinic in Chengdu in 2014 were analyzed. The characteristics of MSM population were analyzed descriptively. The non-conditional logistic regression was used to analyze the risk of HIV infection with different demographic characteristics. Results Of the 1 459 MSM receiving VCT services, 67.77% were under the age of 30, 66.88% were unmarried, 51.66% were college and above, and HIV positive rate was 12.16%. Multivariate analysis showed that the risk of divorced or widowed HIV infection was higher (divorced or widowed) than unmarried married persons, followed by unmarried persons (OR = 2.104). Age groups and marital status were also associated with HIV infection. (OR = 2.106). The prevalence of HIV infection among those who were previously infected was higher than those who did not (OR = 1.539). The risk of HIV infection among syphilis patients was higher than that of those without HIV infection (OR = 5.818). Conclusion The detection rate of HIV positive in MSM population of VCT clinic in Chengdu is relatively high. MSM of different characteristics have different risk of infection. Therefore, counseling, testing and intervention services should be carried out in a targeted manner.
