目的 分析我国东部、中部和西部地区活动性肺结核患病率的差异 ,为采取相应的控制措施提供依据。方法 利用 2 0 0 0年全国结核病第 4次流行病学调查数据 ,并结合各省实际人口数 ,对 3个地区进行比较分析。结果 活动性肺结核患病率由东向西逐渐增高 ,东部低于全国平均水平 ,西部和中部高于全国平均水平。活动性肺结核患病率分别是东部地区的 1 775倍与 1 761倍 ,西部和中部与东部的差异有统计学意义 (P <0 0 1) ,西部与中部之间的差异没有显著意义。结论 我国东部的结核病患病率明显低于中部和西部。
Objective To analyze the difference of the prevalence of active tuberculosis in the eastern, central and western areas of our country and provide evidence for the corresponding control measures. Methods According to the 4th national epidemiological survey of tuberculosis in 2000 and the actual population of each province, the comparative analysis of 3 regions was made. Results The prevalence of active tuberculosis increased gradually from east to west, the eastern part was lower than the national average, the western part and central part were higher than the national average. The prevalence of active tuberculosis was 1775 times and 1 761 times respectively in the eastern part of China. There was a significant difference between the west part and the central part and the eastern part (P <0.01). There was no significant difference between the west part and the middle part. Conclusion The prevalence of tuberculosis in eastern China is obviously lower than that in central and western areas.
