【摘要】：目的了解湖南省肺结核空间分布规律,确定肺结核重点防疫区域,为制定肺结核防治对策与措施提供科学依据。方法收集湖南省2012年1月—2013年12月新涂阳肺结核患者登记的相关信息和数据,应用ArcGIS 10.2软件制作肺结核空间分布地图,并采用空间自相关和趋势面分析探索其发病的聚集性和热点区域。结果湖南省2012和2013年新涂阳肺结核患者登记率分别为40.6/10万和36.4/10万;全局自相关分析结果显示,2012和2013年湖南省新涂阳肺结核患者登记率的Moran'I统计量分别为0.86和0.58(Z=17.89、12.06,均P0.05),均存在空间聚集性;局部空间自相关结果显示,2012年凤凰县、泸溪县、吉首市、花垣县、保靖县、永顺县、武陵源县、古丈县、永定区、桑植县、慈利县等11个县(市、区)存在高高聚集,2013年凤凰县、泸溪县、吉首市、花垣县、保靖县、武陵源县、古丈县、永定区、桑植县、慈利县等10个县(市、区)存在高高聚集;趋势面分析结果显示,2012和2013年湖南省肺结核总体分布由西至东呈一条直线逐渐降低,由南至北2012年呈明显"U"形,2013年呈轻微"U"形。结论2012和2013年湖南省分别有11和10个县(市、区)存在新涂阳肺结核患者登记率高高聚集,新涂阳肺结核患者登记率在湖南省西部地区高于东部地区,南北地区高于中部地区。
[Abstract]:Objective to understand the spatial distribution of pulmonary tuberculosis in Hunan Province, and to determine the key areas of tuberculosis prevention and control, and to provide scientific basis for the formulation of tuberculosis prevention and control strategies and measures. Methods the information and data of new smear positive pulmonary tuberculosis patients in Hunan province from January 2012 to December 2013 were collected, and the spatial distribution map of pulmonary tuberculosis was made by using ArcGIS 10.2 software. Spatial autocorrelation and trend surface analysis were used to explore the clustering and hot spots of the disease. Results the registration rates of new smear positive pulmonary tuberculosis patients in Hunan Province in 2012 and 2013 were 40.6 / 100,000and 36.4 / 100000, respectively. The results of global autocorrelation analysis showed that the Moran'I statistics of the registration rate of new smear positive pulmonary tuberculosis patients in Hunan Province in 2012 and 2013 were 0.86 and 0.58, respectively (P 0.05, P 0.05). Local spatial autocorrelation results show that 11 counties (cities and districts) such as Fenghuang County, Luxi County, Jishou City, Huayuan County, Baojing County, Yongshun County, Wulingyuan County, Guzhang County, Yongding District, Sangzhi County, Cili County, and other 11 counties (cities, districts) gathered high in 2012. Fenghuang County, Luxi County, Jishou City, Huayuan County, Baojing County, Wulingyuan County, Guzhang County, Yongding District, Sangzhi County, Cili County and other 10 counties (cities, districts) have high gathering; The results of trend surface analysis showed that the overall distribution of pulmonary tuberculosis in Hunan Province decreased gradually from west to east in 2012 and 2013, obviously in "U" form from south to north in 2012, and slightly "U" in 2013. Conclusion there are 11 and 10 counties (cities, districts) in Hunan Province in 2012 and 2013, respectively, where the registration rate of new smear positive pulmonary tuberculosis patients is high. The registration rate of new smear positive pulmonary tuberculosis patients is higher in the western part of Hunan Province than in the eastern region, and in the north and south areas higher than that in the central region.
