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(χ2=26.48,P=0.000);接尘组男性翼状胬肉检出率高于女性(χ2=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。
Objective To investigate the correlation between productive dust and pterygium. Methods A total of 619 employees from cement plants, feed mill and coating factory in Nanning City were examined with ophthalmology. The data were analyzed by t-test, chi-square test and Spearman correlation analysis. Results The average age of exposed dust group was higher than that of non-infected group (t = 0.398, P = 0.691). The average length of service in dust exposure group was higher than that in non-exposure group, and the difference was not statistically significant (T = 5.398, P = 0.000). The detection rate of pterygium in the dust collection group was higher than that in the non-infection group (χ2 = 26.48, P = 0.000) (Χ2 = 8.73, P = 0.003); there was no correlation between the length of service and the detection rate of pterygium (spearman’s R = 0.11, P = 0.893); no correlation between length of service and pterygium There was no correlation between rates (spearman’s R = -0.039, P = 0.531). Conclusion Soot is an influencing factor in the pathogenesis of pterygium.
