摘要
目的分析2010—2012年西安市艾滋病病毒（HIV）感染人群的分布状况和变化趋势，为制定更加有效的艾滋病防治策略提供科学依据。方法收集2010—2012年HIV抗体确证阳性样本，横向分析样本人群来源及年龄、职业分布．纵向比较数据的年度变化，统计分析揭示数据背后的流行病学规律。结果由于监测力度增大，HIV抗体确证阳性样本逐年增加，2010—2012年分别检出372人、643人、808人，男性占90．O％，女性占10．O％。阳性样本在男男人群（MSM）和非婚异性性接触传播人群中所占比例最高，分别为45．4％和34．0％。MSM占阳性人群比例由32．5％增加到49．6％（P〈O．01）。MSM年龄多集中在15～45岁之间，大专及以上学历者占该人群的47．5％。非婚异性性接触感染阳性构成比3年分别为28．5％、31．7％、38．3％（P〈0．01）。注射毒品、输血／血制品及母婴传播3种途径的感染构成比呈逐年下降趋势。〈15岁感染者为母婴传播。结论3年来西安市HIV感染阳性人数逐年增加，感染人群的分布及构成变化不同．因此．应该根据检出阳性人群的分布特征制定出更加合理有效的防治策略。
Objective To analyze the distribution of population confirming HIV antibody positive and their trend from 2010 to 2012 in Xi＇an, and provide evidence for the formulation of strategies for HIV/AIDS prevention and control. Methods The laboratory antibody detection data from 2010 to 2012 in Xi＇an was analyzed and compared, in order to discover epidemiological characteristics underlying these laboratory data. Results Confirmed positive samples increased because of the increase in the number of people monitored. 372, 643 and 808 positive cases were detected from 2010 to 2012, respectively. Males accounted for 90.0 %, and females 10.0%. The highest rates were found in men who have sex with men （MSM） and non-marital homosexual transmission group, 45.4% and 34.0%, respectively. MSM＇s proportion of HIV positive people increased from 32.5% to 49.6%, （trend test, P〈0.01 ）, and MSM ages were in 15-45 ,with college and above education level accounted for 47.5% among the total MSM positive people. In the past three years , the ratio of non-marital homosexual transmission group infected HIV positive were 28.5%, 31.7%, and 38.3%, respectively, showing significant difference （P〈0.01）. However, the positive ratio of injecting drug-users, the blood transfusion/blood products and the mother-infant transmission had declined year by year; less than 15-year-old infected people were found to be transmitted by mother-infant transmission. Conclusion The HIV infected cases of Xi＇an increased in the past three years, the constitute and the changes were different in different categories among HIV positive populations. Therefore, disease control departments should formulate a series of reasonable and effective prevention strategies according to the distribution characteristic of people with confirmed positive of HIV antibody.
