某矿业集团1107例尘肺患者合并结核调查

Investigation on pneumoconiosis complicated with tuberculosis among 1107 patients in a coal mine industry group

目的了解某矿业集团尘肺合并结核的合并率及影响因素,从而为尘肺结核的防治措施提供依据。方法对某矿业集团1107例尘肺患者进行流行病学问卷调查,按照全国尘肺流行病学调查办公室设计的统一方案填写"尘肺病例卡"所有内容,将所得资料用Excel2000建立数据库,以SAS8.2统计软件包进行统计学处理。结果①某矿业集团,总的尘肺合并结核率为30.5%,现患尘肺患者的结核合并率比死亡尘肺患者合并结核率低,分别为11.6%和37.3%,两者差异有统计学意义(х2=113.78,P<0.0001);②随着尘肺期别增加,尘肺结核合并率明显上升,其中Ⅰ期尘肺合并结核率为18.4%(103/561),Ⅱ期尘肺合并结核率为23.7%(61/257),Ⅲ期尘肺合并结核率为60.9%(176/289);③影响尘肺合并结核的因素有尘肺期别。结论尘肺易合并结核,其合并率随尘肺期别的增加而增高,尘肺结核的发生与尘肺期别有关。

Objective To find out the rate of pneumoconiesis complicated with tuberculosis and the risk factors, in order to provide scientific criteria for the prevention of pneumoconiosis complicated with tuberculosis. Methods An epidemiology questionnaire survey was carried out in 1 107 pneumoconiosis patients in a mining industry group, and all contents were filled in ＂ill- ness card of pneumoconiosis case＂ according to the national pneumoconiesis epidemiology unified plan designed by the office of investigation. A database was built with Excel 2000 and the data were processed by SAS 8.2 statistics software package. Results ① The total rate of pneumoconiesis complicated with tuberculosis was 30. 5%, and the complicated rate of pneumoconiosis tubereulesis among the prevalent cases （ 11.6% ） was lower than that of the death pneumoconiesis cases （37.3%）, showing significant difference （Х^2 = 113.78, P 〈 0. 000 1 ）. ②Along with the stages of pneumoconiosis increasing, the rate of complicated tuberculosis rose obviously. The rate of stage I was 18.4% （103/561）, the rate of stage Ⅱ 23.7% （61/257）, and the rate of stage m 60. 9% （176/289）. ③ Risk factors of pneumoconiosis complicated with tuberculosis were observed to be the stage of pneumoconiosis, type of work, the working-age and the times of dust exposure. Conclusion The coal workers with pneumoconiosis are prone to complicate tuberculosis, and the complication rate rises along with the stages of pneumoconiesis increasing. The occurrence of pneumoconiesis complicated with tuberculosis is related to the working-age and the times of dust exposure.
