Abstract:
OBJECTIVETo study the effect of smoking and rush-mat dust exposure on pulmonary function.
METHOD122 rush-mat dust exposed workers and 118 controls without dust exposure were selected. Questionnaire and FEVY1.0 measurement were performed on them.
RESULTSFor dust exposure, FEV1.0% of cases (81.8% +/- 13.9%) was statistically lower than controls (95.9% +/- 15.3%) (t = -7.49, P < 0.01), the abnormal rate of FEV1.0% was 46.7% (57/122) for cases, statistically higher than controls (8.5%, 10/118), chi2 = 43.6, P < 0.01. For smoking, FEV1.0% of cases (82.02% +/- 12.9%) was statistically lower than controls (93.33% +/- 12.4%), t = -5.18, P < 0.05, the abnormal rate of FEV1.0% is 55.9% for cases, statistically higher than controls (16.7%), chi2 = 22.2, P < 0.05. The exposing ages of workers has negative correlation with FEV1.0% (R(S1) = -0.299, P = 0.0008). Exposure and smoking could affect FEV1.0% (Fe = 259.06, P < 0.01, F(s) = 42.42, P < 0.01), and their interactive effect on FEV1.0% was greater than single ones (F = 34.70, P < 0.01).
CONCLUSIONRush-mat dust exposure, smoking and their interaction have influence on FEV1.0%.
