摘　　要：目的分析2008—2019年四川省经注射吸毒(injection drug use,IDU)感染的艾滋病病毒感染者/艾滋病病人(简称“HIV/AIDS”)的时空聚集特点。方法应用SPSS 22.0软件对2008—2019年四川省报告的经IDU感染的HIV/AIDS病例进行χ_(趋势)^(2)分析,应用Arcgis 10.7和Arcgis pro 2.7软件进行自相关分析和新兴时空热点分析。结果2008—2019年全省共报告32414例经IDU感染的HIV/AIDS病例,历年报告数占比总体呈下降趋势(χ_(趋势)^(2)=26853.229,P<0.0001)。全省历年报告HIV/AIDS病例均有聚集性(Moran’s I>0,Z>1.96,P<0.0001),热点区域主要聚集在凉山州的各个县(市)以及周边的石棉县、米易县等;时空聚集性分析发现5种聚集类型,凉山州的西昌市、布拖县等9个县(市)为加强热点,冕宁县和宁南县为连续热点,普格县为持续热点,德昌县为新增热点,雅安市的石棉县为分散热点。结论四川省经IDU感染HIV疫情有所缓解,后续针对IDU感染HIV的防控主要集中在凉山州,尤其是聚集性逐年加强的西昌市、德昌县等9个地区应加大防控力度,分析相关影响因素并提出针对性的防控措施。Objective To analyze the spatio-temporal clustering characteristics of HIV/AIDS infection through injecting drug use(IDU)in Sichuan Province from 2008 to 2019.Methods Chi-square trend test was used to analyze the trend of HIV/AIDS cases infected by IDU in Sichuan Province from 2008 to 2019.The autocorrelation and spatiotemporal analysis were performed by Arcgis 10.7 and Arcgis pro 2.7 software.Results From 2008 to 2019,a total of 32414 HIV/AIDS cases infected by IDU were reported in Sichuan Province.and the number of reported cases showed a decreasing trend(χ^(2)=26853.229.P<0.0001).HIV/AIDS cases were clustered in the province over the years(Moran’s I>0,Z>1.96,P<0.0001),and the hot spots were mainly concentrated in each county of Liangshan Prefecture as well as the surrounding Shimian and Miyi county.There are five types of clustering,including the strengthening hot spots(Xichang and Butuo and other seven regions in Liangshan Prefecture),continuous hot spots(Mianning and Ningnan),a persistent hot spot(Puge),a new hot spot(Dechang),and a scattered hot spot(Shimian in Yaan City).Conclusions The epidemic status of HIV infection through IDU has alleviated.The follow-up prevention and control for HIV infection through IDU mainly concentrated in Liangshan Prefecture.Particularly,we should strengthen prevention and control of HIV infection,monitor relevant factors and propose targeted prevention and control measures in Xichang,Dechang County and other seven regions.
