目的调查和了解我国性罪错人群人口流动和艾滋病病毒(HIV)感染状况。方法在31个省(自治区、直辖市)和新疆生产建设兵团的监管场所中开展性罪错人群的人口学特征和HIV感染率调查,采用χ~2检验分析不同性别性罪错人员流行病学特征,并采用MapInfo 15.0软件绘制各省感染率及省间流动状态图。结果本研究对80 660名新入所的性罪错人群开展的调查表明,HIV抗体总阳性率为1.86%,男性为1.91%,女性为1.48%,其中部分省份男女性感染率差异有统计学意义。男、女性性罪错人员流出地均以中部和西南省份为主,流入地以东部沿海和较发达地区为主。在押的性罪错人员中,男性流动人口的HIV感染率高于非流动人口(χ~2=22.978,P=0.001);女性流动人口HIV感染率低于非流动人口(χ~2=9.910,P=0.002)。结论监管场所性罪错人群HIV感染率较高,且省间流动频繁,应加强对该人群尤其是男性流动人群的艾滋病预防干预工作。
Objective To investigate and understand the population misconduct in China and the status of HIV infection. Methods To investigate the demographic characteristics and HIV prevalence of sex offenders in the regulatory sites of 31 provinces (autonomous regions and municipalities directly under the Central Government) and Xinjiang Production and Construction Corps (XPCPCS), and to study the epidemiological characteristics of sexually transgressive individuals with different sex by using Chi-square test Using MapInfo 15.0 software to draw the provincial infection rate and the inter-state flow chart. Results The survey of 80 660 new-sex offenders showed that the total positive rate of HIV antibody was 1.86%, 1.91% for males and 1.48% for females. There were significant differences in the infection rate of male and female in some provinces. The outflow of male and female sex offenders were mainly from the central and southwestern provinces, with inflows mainly dominated by the east coast and the more developed regions. The HIV infection rate of male migrants was higher than that of non-migrants (χ ~ 2 = 22.978, P = 0.001). The HIV prevalence of female migrants was lower than that of non-migrants (χ ~ 2 = 9.910, P = 0.002). Conclusions HIV infection rate is high in the sex offenders in regulatory sites, and the flow between provinces is frequent. HIV / AIDS prevention interventions should be strengthened for this population, especially for male migrants.
