目的 分析2009-2013年甘肃省肺结核报告发病率的时空及发病聚集区分布特征。方法 采用空间统计学方法, 利用2009-2013年甘肃省肺结核报告发病率数据, 以区(县)水平计算其空间分布的全局、局部自相关系数, 并分析时空分布特征。结果 2009-2013年甘肃省肺结核报告发病率存在空间相关性(P<0.001);局部G统计量分析显示热点区域主要分布于河西地区、临夏州、定西部分县区(渭源县、漳县、岷县、安定区), 冷点区域主要分布于兰州市、定西地区部分县区(陇西县、通渭县)、天水市、平凉市及庆阳市部分县区;时空分析结果显示, 2009-2013年甘肃省肺结核报告发病率存在时空聚集性, 高发病率最大可能聚集区分布于河西地区, 聚集时间为2009-2010年(LLR=3 031.10, RR=2.27, P<0.001), 低发病率最大可能聚集区分布于兰州市, 聚集时间为2011-2013年(LLR=1 545.52, RR=0.37, P<0.001)。结论 2009-2013年甘肃省肺结核报告发病率存在空间和时空聚集区域, 河西地区是甘肃省肺结核防控的重点地区。 |

Objective To understand the spatial-temporal specific incidence of pulmonary tuberculosis (TB) in Gansu. Methods The county-based incidence of pulmonary TB in Gansu from 2009 to 2013 was used to calculate Moran's I and G statistics, and analyze the spatial-temporal distribution of areas with different pulmonary TB incidences. Results The spatial correlation in incidence of pulmonary TB was found in Gansu from 2009 to 2013 (P<0.001), and the hot spot areas were mainly in Hexi area, Linxia, part of Dingxi, while the cold spot areas were in Lanzhou, part of Dingxi, Tianshui, Pingliang and Qingyang. Spatial-temporal analysis showed that the clustering of high pulmonary TB incidence areas were most likely in the Hexi area during 2009-2010 (LLR=3 031.10, RR=2.27, P<0.001), and the clustering of low pulmonary TB incidence areas were most likely in Lanzhou during 2011-2013(LLR=1 545.52, RR=0.37, P<0.001). Conclusion The analysis on spatial and spatial-temporal specific incidences of pulmonary TB in Gansu from 2009 to 2013 indicated that Hexi area is the key area in pulmonary TB prevention and control in Gansu. |
