摘要目的 分析2005年至2014年浙江省结核病报告的空间分布特征,找出聚集区域.方法 运用空间扫描统计量的分析方法,对2005年至2014年浙江省结核病登记报告的数据进行统计分析和结果展示.结果 2005年至2014年浙江省共登记报告结核病患者377707例,全省年均登记率为72.61/10万(28.85/10万~182.90/10万).空间扫描结果显示,全省共14个聚集性区域(RR=1.05~1.62),差异均有统计学意义(均P<0.05);时间扫描结果显示,2005年至2009年存在结核病患者登记的聚集现象(RR=1.27,P=0.001);时空扫描结果显示,全省共6个聚集区域(RR=1.19~3.55),差异均有统计学意义(均P<0.05).空间扫描分析的一级聚集区域所包含的县(市)与时空扫描结果基本一致.结论 浙江省结核病登记报告呈由西向东逐渐递减的趋势,在时间、空间和时空水平都具有明显的聚集现象,并非随机分布.

abstractsObjective To analyze the epidemic characteristics of tuberculosis (TB) cases in Zhejiang province from 2005 to 2014, and to identify the cluster spots.Methods TB notification data in Zhejiang province from 2005 to 2014 were analyzed at county and district level by using spatial scan statistic analysis method, which was showed on the digital map.Results In zhejiang province from 2005 to 2014, a total of 377 707 cases of patients with tuberculosis were reported.The average annual registration rates of the entire province was 72.61/100 000 (range: 28.85/100 000-182.90/100 000).Spatial analysis identified 14 clusters (RR=1.05-1.62) with statistical significance.Temporal analysis revealed that there were clusters between 2005 and 2009 in terms of the notification data on TB cases (RR=1.27,P=0.001).Spatio-temporal analysis identified 6 clusters (RR=1.19-3.55) with statistical significance.Counties and districts included in the first class cluster were similar by using the two different methods-spatial analysis and spatial-temporal analysis.Conclusions There is a descending trend of TB cases notification rates from western to eastern Zhejiang during the study period.The distribution of the TB case notified is not random at spatial, temporal and spatio-temporal levels.
