本文对79名棉絮加工女工和73名对照女工的肺通气功能四项参数进行了对比分析,结果是(1)观察组的FEV_1、FEV_1/FVC、MMEF显著低于对照组,肺通气功能异常率明显高于对照组;(2)接尘工龄15年以上者FEV_1、FEV_1/FVC、MMEF显著低于低接尘工龄组,肺通气功能异常率明显高于低接尘工龄组;(3)接尘工龄15年以上者FEV_1、FEV_1/FVC、MMEF的异常率与对照组比较AR分别增加了15.15％、23.68％、25.48％,RR分别增加了4.22、5.09、4、66倍。
In this paper, we compared and analyzed the four parameters of pulmonary ventilation in 79 cotton-wool-processing women and 73 control women. The results were: (1) The FEV_1, FEV_1 / FVC and MMEF in the observation group were significantly lower than those in the control group (2) The FEV 1, FEV 1 / FVC and MMEF were significantly lower than those in the low dust exposure age group, and the abnormality rate of pulmonary ventilation function was significantly higher than those in the low dust exposure age group (3) The abnormal rates of FEV_1, FEV_1 / FVC and MMEF in dust-exposed workers aged 15 years or more were 15.15%, 23.68% and 25.48% higher than those in the control group, respectively. The RRs increased by 4.22, 5.09 and 4.66 times, respectively.
