目的掌握西安市艾滋病病毒(HIV)阳性男男性行为者(MSM)的流行病学特征,为今后艾滋病(AIDS)的防控工作提供依据。方法采用描述性流行病学分析方法,对2010-2014年感染HIV MSM的疫情监测信息和流调资料进行分析。结果2010-2014年,HIV阳性MSM的人数占同期HIV感染者人数的62.24%(1302/2092)。经自愿咨询并接受检测从而被发现感染HIV的MSM的构成,已从13.41%上升到39.23%;而专题调查被发现者的构成则从59.76%下降至31.72%,差异有统计学意义(χ2趋势=32.676,P=0.000)。HIV阳性MSM中30岁以下者占53.92%(702/1302);受过高等教育者占54.99%(716/1302);其他职业、家务待业及商业服务者合计占全部HIV阳性MSM的58.60%(763/1302);未婚者、离异或丧偶者分别占了67.97%和17.20%。结论HIV阳性MSM具有年青、文化程度较高、职业稳定性相对较差、非婚状态者为多等特征,应有针对性地开展干预活动。
Objective To grasp the epidemiological characteristics of HIV-positive MSM in Xi’an, and to provide basis for the future prevention and control of AIDS. Methods Descriptive epidemiological analysis was used to analyze the surveillance information and epidemiological data of HIV-infected MSM in 2010-2014. Results From 2010 to 2014, the number of HIV-positive MSM accounted for 62.24% (1302/2092) of HIV-infected persons during the same period. The composition of MSM found to be HIV-infected by voluntary counseling and testing increased from 13.41% to 39.23%, while the incidence of the surveyed respondents dropped from 59.76% to 31.72% with a statistically significant difference (χ2 trend = 32.676, P = 0.000). HIV-positive MSM accounted for 53.92% (702/1302) under the age of 30; 54.99% (716/1302) had higher education; 58.60% (763%) of other occupations, home-based and business people together accounted for HIV-positive MSM / 1302); unmarried persons, divorced or widowed accounted for 67.97% and 17.20% respectively. Conclusion HIV-positive MSM is young, with a high level of education, relatively poor occupational stability and multiple non-marital status, and should be targeted to carry out interventions.
