[Matching study of lung function and respiratory symptoms in ex-dust exposure miners].
The lung function tests and respiratory symptom investigations were carried out on 156 pairs of ex-dust exposure miners and control workers according to match designing method. The matching was based on age, height, weight and smoking habit. The result showed that ex-dust exposure miners had higher frequency of abnormal lung function than that of control workers. Compared with control workers, the prevalence of respiratory symptoms and the incidence of chronic bronchitis were higher in ex-dust exposure miners.
