摘要目的 探讨蔺草粉尘接触与吸烟对工人第1秒用力呼气量(FEV1.0)的影响.方法 选择蔺草接尘工人122名为接触组,118名非接尘人员为对照组,进行问卷调查和FEVL11.0的测定,分析粉尘接触与吸烟对工人FEV1.0的影响.结果 接尘组FEV1.0%(81.8%±13.9%)明显低于对照组(95.9%±15.3%),差异有统计学意义(t=7.49,P＜0.01).接尘组FEV1.0%异常率为46.7%(57/122)明显高于对照组(8.5%,10/118),差异有统计学意义(x2=43.6,P＜0.01).吸烟组FEV1.0%(82.02%±12.9%)明显低于不吸烟组(93.33%±12.4%),差异有统计意义(t=5.18,P＜0.05).吸烟组FEV1.0%异常率(55.9%)明显高于不吸烟组(16.7%).差异有统计意义(x2=22.2,P＜0.05).接尘工龄与FEV1.0%呈负相关,差异有统计学意义(Rs1=-0.299,P=0.0008).接尘与吸烟对FEV1.0%有影响(F吸烟=42.42,F接尘=259.06.均P＜0.01),且接尘与吸烟的交互作用影响大于单独效应(F=34.70,P＜0.01).结论 粉尘接触、吸烟及其联合作用可影响蔺草工人的肺功能.

abstractsObjective To study the effect of smoking and rush-mat dust exposure on pulmonary function. Method 122 rush-mat dust exposed workers and 118 controls without dust exposure were selected.Questionnaire and FEV1.0 measurement were performed on them. Results For dust exposure, FEV1.0% of cases (81.8%±13.9% ) was statistically lower than controls (95.9%±15.3% )(t=-7A9,P＜0.01 ),the abnormal rate of FEV1.0% was 46.7%(57/122) for cases, statistically higher than controls (8.5%,10/118),x2=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% ),x2=22.2, P＜0.05.The exposing ages of workers has negative correlation with FEV1.0% (Rs1 =-0.299, P =0.0008).Exposure and smoking could affect FEV1.0% (Fe =259.06, P＜0.01, Fs =42.42, P＜0.01 ),and their interactive effect on FEV1.0%was greater than single ones (F=34.70,P＜0.01). Conclusion Rush-mat dust exposure, smoking and their interaction have influnce on FEV1.0%.
