| Abstract: |
| 目的 对近年全国新涂阳肺结核登记进行聚集性分析, 找出聚集区域和研究其中原因。方法 通过空间扫描统计登记数据, 利用地理信息系统展示结果。结果 空间分析共发现6个聚集性区域, RR=1.03~1.83, 且差异均有统计学意义;时间分析发现, 2005-2007年存在新涂阳肺结核患者登记的聚集现象, RR=1.27(P=0.001);时空分析共发现2个聚集区域, 一、二级聚集K域的值分别为1.35和1.49, 差异均有统计学意义。其中一级聚集区域所包含的省份与空间分析结果基本一致。结论 中国各地区新涂阳肺结核患者登记在时间、空间和时空上均不是随机分布, 存在聚集现象。 |

| Objective To analyze the notification status on new sputum-smear positive pulmonary tuberculosis (TB) over the recent years in China, and identify the clusters to address the related reasons. Methods To spatially and temporally scan the data regarding notification, and to display the results via geographic information system. Results (1) Spatial analysis identified 6 clusters and their relative risks ranged from 1.03 to 1.83 with statistical significance； (2) Temporal analysis identified there were clusters between 2005 and 2007 in terms of notification on new sputum-smear positive pulmonary TB, and the relative risk was 1.27 (P=0.001)； (3) Spatial and temporal analysis identified 2 clusters and the relative risks of the first class cluster and the second class cluster were 1.35 and 1.49 respectively with statistical significance. Provinces included in the first class cluster were basically the same as these in spatial analysis. Conclusion Distribution of the notification on new sputum-smear positive pulmonary TB was not stochastic at space, time and space-time, and clusters did exist in China. |
