尘肺并发慢性阻塞性肺疾病研究

Research on pneumonoconiosis complicated with chronic obstructive pulmonary disease

目的了解尘肺并发慢性阻塞性肺疾病（COPD）的患病情况，并探讨其影响因素。方法以湖南省5家省级矿业公司近5年新诊断尘肺的患者为研究对象，对受试者进行肺功能、胸片检查，并收集其一般资料。分析尘肺患者COPD患病率情况及其影响因素。结果相同年龄阶段，尘肺患者COPD患病率明显高于普通人群。随着尘肺期别、接尘时间、年龄、吸烟强度的增加，尘肺患者COPD患病率有增高的趋势。50岁以后尘肺患者COPD患病率明显增高。尘肺并发COPD的患者BMI较尘肺非COPD患者低。结论①尘肺患者COPD患病率明显高于普通人群。②尘肺期别、接尘时间、吸烟、吸烟指数、年龄、BMI为COPD患病的影响因素。③尘肺期别是尘肺并发COPD的最大影响因素。

Objective To learn the situation of pneumonoconiosis patients complicated with chronic obstructive pulmonary disease （COPD） and explore its influencing factors. Methods Select newly diagnosed of pneumoconiosis patients in recent 5 years in the 5 provincial mining company in Hunan province as the research object. The subjects performed spirometry, a chest radiograph, meanwhile to collect their general information. Learn the situation of pneumonoconiosis patients complicated with COPD and its influencing factors. Results In the same age class, the incidence of COPD significantly higher than the general population. With the stage, the length of service, the age, smoking intensity increasing, the prevalence of COPD in pneumonoconiosis patients is increasing. Incidence rate of COPD increased obviously in pneumoconiosis patients after the age of 50. The BMI of COPD is lower than that of non- COPD in pneumonoconiosis patients. Conclusions ① Pneumoconiosis patients have higher incidence of COPD than general population. （2）Stages of pneumoconiosis, exposure duration, smoking, smoking index, age and BM1 are influencing factors of COPD. ③Stages of pneumoconiosis is the biggest influencing factors for pneumoconiosis complicated with COPD.
