职业危害因素与翼状胬肉发病关系的流行病学研究

The epidemic research of the relationship with desease between the harmful elememts and pterygium.

对接触毒物、粉尘、辐射线及混合性因素的3982名工人为接触组,及不接触职业危害的637名为对照组,进行了翼状胬肉的发病调查.结果表明:接触组检出率为9.54%,对照组检出率为5.18%.提示翼状胬肉的发病与接触职业危害因素有密切关系.接触组比对照组高0.34～2.08倍.各工龄组之间的翼状胬肉发病均呈中、高度相关,P<0.001或<0.005.

By examing 3982 workers who have contact with the poisionous matters, tiny dust, radical rays and mixtual factors, and 637 workers who have nothing to do with the above factors, we have an investigation of illness on account of pterygium. The result shows the ratio of the first group is 9.54%, the latter is 5.18%. Hence we know the illness of pterygium is closely related, with harmful elememts of the occupation. The ratio of the pterygium in the touching group is about 0.34 ~ 2.08 times higher than the control group. There is high relationship between different length of service (P< 0.001 or 0.005).
