| 摘 要： | 以2008 年河南省地级市艾滋病分布数据为基础,利用ESDA空间数据挖掘的方法,对河南省艾滋病空间格局进行全面分析。结果表明：① 综合考虑河南省18 个地级市艾滋病确诊人数数据的空间自相关分析结果和不同传播途径感染单因素空间格局的结果,将河南艾滋病感染区域分为以FPD感染途径为主的豫南、豫东南高度流行区和以高危行为传播途径为主的豫北低度流行区;② 河南省艾滋病感染途径分布中,FPD感染、母婴感染、异性传播感染和注射吸毒传播具有明显的空间正相关,而同性传播途径与输血感染则显示出较大的空间随机分布特征;③ 与FPD 感染存在空间正相关的为注射吸毒传播、异性传播以及母婴传播方式,输血、同性以及其他方式传播途径与FPD感染途径分布不存在空间相关性。

| Abstract: | HIV and AIDS infections have become major global health and social problems since the 1980s. There has a high prevalence rate of HIV in Henan Province since the 1990s because of former plasma donors (FPD). In this paper, we use the spatial data analytical methods such as exploratory spatial data analysis (ESDA) to describe the spatial pattern of AIDS infection in Henan in 2008. According to Henan Centers for Disease Control, there are seven main modes of transmission of AIDS in Henan: former plasma donors, homosexual and heterosexual transmission, mother to child transmission (MTCT), drug injection user, blood transfusion and unknown causes of infection. The results showed that: (1) considering the results of the single factor of spatial patterns and the prevalence rate at the municipal level, we divide Henan into two infection areas: the first type is the high prevalence area in the south and the southeast of Henan, and the second one is the low prevalence area in the north of Henan. In the first area, the main infection source is FPD. The main infection in the second area is the high-risk behavior. (2) The results of local spatial autocorrelation indicate that there are significant local clusters in the FPD, MTCT, heterosexual transmission and drug injection, but the homosexual transmission and the blood transfusion are randomly distributed in space. (3) The results of two-factor spatial autocorrelation suggest a strong degree of positive correlation among the HIV infection by FPD and the HIV infection by drug injection, heterosexual transmission and MTCT. There are no spatial relationships among the HIV infection by FPD and the HIV infection by blood transfusion, homosexual transmission and the unknown causes of infection. |
