摘　　要：目的估计广东省三地市吸毒人群及其艾滋病病毒(HIV)感染者的规模。方法应用乘数法,选择各地市公安局戒毒所作为目标机构,采用同伴推动抽样方法(RDS),了解调查者及其毒友中曾经进入各地市戒毒所的比例,三地市各获得六个估计数,取其中位数为各地市吸毒人群的最终估计数。采用RDSAT软件获得HIV感染者的点估计和区间估计值,分别与最终估计数相乘,获得吸毒人群中HIV感染者的规模。结果 3个地市吸毒人群的规模分别为29 267人、16 616人和5904人。HIV感染者规模估计数分别为1288人、964人和130人。结论此次研究对三地市吸毒人群规模进行了估计,同时估算出该人群中HIV感染者的规模,为进一步开展艾滋病预防控制工作提供了依据。Objective To estimate the size of drug users and their human immunodeficiency virus （HIV） infec- tion in three cities of Guangdong province. Methods Mulitiplier method was used in the study. Local Public Securi- ty Bureau detoxification center of each city was selected as targeted institution to obatain the number of registered drug users . Respondent driven sampling was conducted among the drug users in community to obtain the number of drug users. The median of the six estimate numbers was taken as the final. The RDSAT software was used to calcu- late point and interval estimate of HIV infectors in each of the three cities. Then the size of HIV infection among drug users was obtained by multiplying with the final median, respectively. Results The size of drug users in three cities was 29267, 16616 and 5904, respectively. The number of HIV positive infectors was 1288, 964 and 130, respectively. Conclusions The size of both drug users and HIV infectors are estimated in the study,which provides a basis for HIV/AIDS prevention and control.
