目的比较厦门市HIV感染者男男同性传播与异性传播的流行病学特征,为艾滋病防控提供依据。方法收集厦门市1992—2015年报告的HIV感染者资料,对同性传播与异性传播感染者进行流行病学分析。结果厦门市24年间共报告HIV感染者1 610例,其中同性传播674例(41.9%),异性传播853例(53.0%),与异性传播感染者比较,同性传播感染者未婚占比大(75.4%)、文化程度高(≥大专48.4%)、更年轻(<40岁占81.2%)。同性传播者样本来源主要为咨询检测(47.0%)和专题调查(12.8%),异性传播者主要为其它就诊检测(32.8%)和术前检测(22.2%)。同性传播者首次发现HIV抗体阳性1个月内即诊断为艾滋病的比例(7.9%)比异性传播者(17.1%)低。结论同性传播者首次发现HIV抗体阳性1个月内即被诊断为艾滋病的比例更低,可能与该人群更加主动寻求HIV抗体检测有关。
Objective To compare the epidemiological characteristics of homosexual transmission and heterosexual transmission among men who have HIV infection in Xiamen and provide the basis for AIDS prevention and control. Methods The data of HIV infected persons reported from 1992 to 2015 in Xiamen were collected for epidemiological analysis of homosexual and heterosexual transmission. Results A total of 1 610 cases of HIV infection were reported in Xiamen City during the 24-year period, including 674 cases of homosexual transmission (41.9%) and 853 cases of heterosexual transmission (53.0%). Compared with heterosexual transmission patients, the proportion of unmarried persons with same-sex transmission was also high (75.4% %), Highly educated (≥ 48.4% of college), and younger (81.2% of age <40). The source of same-sex communicators was mainly counseling and testing (47.0%) and thematic survey (12.8%). The other sex-communicators were mainly other examinations (32.8%) and preoperative testing (22.2%). For the first time, homosexuals found HIV antibody positive diagnosed as AIDS within one month (7.9%), compared with those who were heterosexual (17.1%). Conclusion For the first time, homosexuals found HIV antibody positive that is diagnosed within 1 month, a lower proportion of AIDS may be more active in this population to seek HIV antibody testing.
