本文报道了130例退休粮工及373例无粉尘接触史的退休工人的呼吸道疾患及肺功能检查的结果,显示接触组的慢性呼吸道疾病症状和体征较对照组有显著意义的升高。肺功能的检查结果表明,接触组的FVC、FEV_1、PEF、V_(75)、V_(50)、V_(25)等指标较对照组有显著的下降,两组的差别有显著及极显著意义。对男粮工与对照组进行了肺功能与接尘、吸烟两因素方差分析,结果表明粉尘和吸烟对V_(50)、V_(250及FEF_(25～75)三项指标有显著的交互作用,即吸烟可以加重粉尘对工人肺功能的影响。
This paper reports the results of respiratory diseases and pulmonary function tests of 130 retired food workers and 373 retired workers without history of exposure to dust. The results showed that the symptoms and signs of chronic respiratory diseases in the exposure group were significantly higher than those in the control group. The results of pulmonary function test showed that the indexes of FVC, FEV_1, PEF, V_ (75), V_ (50) and V_ (25) of the exposed group were significantly decreased compared with the control group, the difference between the two groups was significant and extremely significant . Two-factor analysis of variance (ANOVA) of lung function, dust collection and smoking in male food workers and control group showed that there was a significant interaction between dust and smoking on V_ (50), V_ (250) and FEF_ (25 to 75) , That smoking can increase the impact of dust on the lung function of workers.
