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 understand the epidemiological characteristics of migrant AIDS patients receiving free antiviral therapy (ART) in Beijing, and to provide evidence for the development of related control strategies. Methods Using the data of National AIDS Prevention and Control Information System to collect the demographic characteristics of AIDS patients in floating population, baseline CD + 4T lymphocyte count, diagnosis and initial ART interval. From September 2011 to July 2012, a survey of HIV / AIDS patients from floating population who entered the national free ART in Beijing was conducted to find out the length of stay and referral status in Beijing. Results Of the 1074 newly recruited HIV / AIDS patients in Beijing, household registration accounted for 29.7% (319) and migrants accounted for 70.3% (755). The baseline CD + 4T lymphocyte count before treatment in migrant patients was (203 ± 116) / μL, and the median interval between diagnosis and initiation of ART was 11.3 months. There was no significant difference in gender, ethnicity, education level, marital status, baseline CD + 4T lymphocyte count, diagnosis and treatment interval between the floating population and the census population (P> 0.05) Distribution and occupational distribution differences were statistically significant (P <0.001). Conclusions The AIDS patients receiving ART in Beijing are relatively young, mostly domestic workers and commercial service workers. The number of AIDS patients exceeds the registered permanent resident population. The treatment needs are high and require early detection and treatment.
