生产性粉尘致作业工人翼状胬肉的流行病学调查

目的探讨生产性粉尘与翼状胬肉发病的相关性。方法对南宁市水泥厂、饲料厂、涂料厂等员工619名，进行眼科检查，对所得数据采用t检验、卡方检验及Spearman相关分析进行统计处理。结果接触生产性粉尘组（简称接尘组）平均年龄高于无接害组，但差异无统计学意义（t=0．398，P=0．691）；接尘组平均工龄高于无接害组，差异有统计学意义（t=5．398，P=0．000）；接尘组翼状胬肉检出率（％）高于无接害组（x^2=26．48，P=0．000）；接尘组男性翼状胬肉检出率高于女性（x^2=8．73，P=0．003）；接尘组工龄与翼状胬肉检出率无相关关系（spearman’s R=0．11，P=0．893）；无接害组工龄与翼状胬肉检出率亦无相关关系（spearman’s R=-0．039，P=0．531）。结论烟尘为翼状胬肉发病的一个影响因素。

Epidemiological investigation of industrial dust-induced pterygium among exposure workers

Objective ] To study the correlation between industrial dust and pterygium. Methods] The ophthalmologic examination was conducted in 619 workers from cement plant, feed mills and paint factory, and the result data were analyzed by t test, Chi- square test and Spearman correlation analysis. Results ] The average age of industrial dust exposure group （ exposure group ） was higher than that of non-exposure group, but the difference was not significant （ t =0.398, P =0.691 ）. The average working age of exposure group was significantly higher than that of non-exposure group （ t = 5. 398, P = 0.000 ）. The detection rate of pterygium in exposure group was significantly higher than that of non-exposure group （ X^2 = 26.48, P = 0.000 ）. In the exposure group, the de- tection rate of pterygium in male workers was higher than that in female workers （ X^2 = 8.73, P = 0.003 ）. There was no correlation between working age and the detection rate of pterygium in exposure group （ spearman＇s R = 0.11, P = 0. 893 ） , while the working age had no correlation with the detection rate of pterygium in non-exposure group （ spearman＇s R =-0. 039, P = 0. 531 ）. Conclusion] The industrial dust is one of influencing factors of pterygium.
