北京市接受抗病毒治疗的755例流动人口AIDS病人的流行病学分析

Epidemiological analysis of 755 floating AIDS patients treated with ART in Beijing

目的了解北京市接受免费抗病毒治疗(ART)的流动人口艾滋病(AIDS)病人的流行病学特点,为制定相关防治策略提供依据。方法利用国家艾滋病综合防治信息系统数据,收集流动人口艾滋病病人的人口学特征、基线CD+4T淋巴细胞计数、确诊与开始ART时间间隔等信息。对2011年9月至2012年7月,在北京市进入国家免费ART的流动人口艾滋病病人进行问卷调查,了解在北京市居留时间和转诊情况。结果北京市艾滋病免费抗病毒治疗组新纳入的1074例病例中,户籍人口占29.7%(319人),流动人口占70.3%(755人)。流动人口病人治疗前基线CD+4T淋巴细胞计数平均值为(203±116)个/μL,确诊与开始ART时间间隔中位数为11.3个月。流动人口病人与户籍人口病人在性别、民族、文化程度、婚姻状况、基线CD+4T淋巴细胞计数、确诊与治疗时间间隔等方面的差异无统计学意义(P>0.05),但两者在年龄分布和职业分布方面的差异有统计学意义(P<0.001)。结论在北京接受ART的流动人口AIDS病人,年龄较轻,多为家政和商业服务人员,数量超过户籍人口,治疗需求大,需要更早发现和治疗。

Objective To explore the epidemiological characteristics of floating AIDS patients treated with an tiretroviral treatment （ART） in Beijing, and to provide an evidence for making strategies in HIV/AIDS prevention and control. Methods Data from the China Information System for AIDS Control and Prevention were collected in the respects of demographic characteristics, average baseline CD4 ＋ T cell counts, and the median time interval be- tween diagnosis and treatment. A community-based survey was conducted to investigate residence time in Beijing and referral. Results There were 1074 patients enrolled in the China National Free Antiretroviral Treatment Program in Beijing from September 2011 to July 2012, among which 29.7~ were resident AIDS patients and 70. 3% were float- ing AIDS patients. There were no significant differences in factors such as gender, ethnicity, level of education, ma- rital status, baseline CD/T cell counts, and the time interval between diagnosis and treatment （P〈0.05） between the floating AIDS patients and the resident AIDS patients. The floating AIDS patients was younger than the resident AIDS patients （P〈0. 001）. The average baseline CD4 ＋T cell count was 203 cells/μL, and the median of the time interval between diagnosis and treatment was 11.3 months. Conclusion Floating AIDS patients accepting ART in Beijing were characterized with predominating with male youth, having higher education level, higher rate of unmarried, widely distributed household registrations, mainly transmitted by homosexual behavior, mostly diagnosed in Beijing, and a high demand for ART. Earlier detection and treatment were necessary.
