【摘要】 目的探讨和分析新疆维吾尔自治区(简称全区)艾滋病病毒(HIV)感染者/艾滋病(AIDS)病例(简称HIV/AIDS病例)报告率的空间分布特征和空间自相关关系,及其热点区域随时间的变化趋势,为全区AIDS针对性防控措施的制定和防控资源的优化配置提供参考依据。方法以县市为尺度,对全区2007-2015年HIV/AIDS病人的年报告率应用地理信息系统(Arc GIS)10.2绘制疾病地图,并进行全局及局域空间自相关分析。结果 2007-2015年,历年全局Moran’s I值均>0,最小Z值为2.487,均有统计学意义(P<0.05),提示全区HIV/AIDS病人空间自相关为正相关,存在聚集性。局部空间自相关分析显示,聚集类型以"高-高"、"低-低"聚集类型为主,随时间推移高-高聚集区域面积扩大,并且由北向南转移域。结论空间自相关分析可以较好地揭示全区HIV/AIDS病人的空间聚集性,防止高-高聚集区域的扩大和AIDS的蔓延。更多还原

【Abstract】 Objective To explore and analyze the spatial distribution features and spatial autocorrelation of human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS)in Xinjiang Uygur autonomous region(Xinjiang)from 2007 to 2015,and to discuss the variation with time of the HIV/AIDS cases clustering areas.Methods Arc GIS(Geographic Information System)10.2was used to map the notation incidence,to identify the spatial clusters,and to analyze the globe and local spatial autocorrelation of HIV/AIDS at county level from 2007to2015 in Xinjiang.Results The annual global Moran’s I indexes from 2007 to 2015were all higher than 0,and the minimum Z-value was 2.487(all P<0.05),indicating that positive spatial autocorrelation existed in HIV/AIDS and there were clusters of HIV/AIDS in Xinjiang.Local spatial autocorrelation analysis revealed that the main cluster types were H-H and L-L.Cluster regions expanded from the northern to southern Xinjiang with time.Conclusion Spatial autocorrelation and distribution can be applied to reveal the spatial clusters of HIV/AIDS in Xinjiang.Health departments should strengthen HIV/AIDS prevention and control in the areas with spatial clustering of the epidemic.更多还原
