中文摘要:
      目的 分析2005--2011年中国注射吸毒人群艾滋病流行的空间分布特点及其变化趋势。方法 利用全国艾滋病综合防治信息系统中2005--2011年注射吸毒途径的HIV感染者和艾滋病患者(HIV/AIDS)数据,分析其人口学特征,分别以省份和区县为水平进行空间聚集性分析,并生成热点区县的中心位点。结果 注射吸毒HW/AIDS的性别比、本省户籍与外省户籍比随时间变化而下降,2011年比值分别为6.75和7.01,HIV与AIDS报告例数比则为上升趋势(Z=26.880,P<0.01)。2005年后全国注射吸毒HIV/AIDS例数、以省为水平的空间聚集性及热点省数量呈下降趋势,2009--2011年全国热点省均为2个(四川、云南省);但以区县为水平的空间分析显示,2010--2011年空间聚集性及热点区县数量有所增加,2005--2011年西部热点区县中心位点局限于新疆,西南部热点区县中心位点有北移倾向。结论 2005—2011年中国注射吸毒人群HIV/AIDS的人口学特征变化具有规律性,表现为省级水平空间聚集性下降,但区县级水平的聚集性和局部热点数量有所增加,且热点出现由边境向内陆地区转移的趋势。
英文摘要:
      Objective To analyze the spatial distribution of HIV/AIDS epidemics among injecting drug users (IDUs) in China from 2005 to 2011 and to understand its changing trend. Methods Using data on people living with HIV and AIDS through injecting drug between 2005 and 2011 to analyze the demographic characteristics of injecting drug users. Analysis on spatial correlation (provincial level and country level ) and median center of hot spots ( country level ) were conducted by Arcgis software. Results Sex ratio (male/female) and registered place ratio (province/other provinces) reduced as time went by,with the ratios in 2011 as 6.75 and 7.01 respectively. Tape ratio of the disease between HIV and AIDS showed an upward trend (Z=26.880, P<0.01).Since 2005,the identified numbers of HIV/AIDS and the spatial correlation and hot spots in provincial level had reduced, the numbers of provincial hot spots were two from 2009 to 2011 (Sichuan and Yunnan provinces) at the national level. However, the spatial correlation and hot spots at the provincial level had an increasing trend. Between 2005 and 2011, the Western Median Centers of hot spots was located in Xinjiang province while the Southwestern Median Center of hot spots tended to move towards the north. Conclusion The demographics changes of HIV/AIDS infection amongecting drug users seemed to be regular from 2005 to 2011. Spatial correlation at the provincial level was reducing. However, the spatial correlation and the numbers of hot spots at the country level increased, with hot spots at the country level tended to move from the border areas towards inland.
