对２７１名焦化作业组女工及对照组１８３名女工的月经情况进行了调查。结果表明，作业组未婚女工月经异常、经量过多发生率比对照组高，但无统计意义（ＲＲ分别为１．４６和１．６６，Ｐ＞０．０５）；作业组已婚女工月经异常、经量过多、经期延长则高于对照组（Ｐ＜０．０５），经Ｌｏｇｉｓｔｉｃ回归分析表明，月经异常、经量过多、经期延长与焦化作业环境相关联。焦化作业环境中存在多种职业有害因素，除苯溶物（ＢＳＯ）超过国外标准外，其它毒物均未超标。
The menstrual status of 183 women workers from 271 coking workgroup women and control group were investigated. The results showed that the unmarried female workers in the working group had abnormal menstruation and the incidence of excessive menstrual flow was higher than that of the control group (RR = 1.46 and 1.66, P> 0.05) Abnormal, over-volume, menstrual prolongation was higher than the control group (P <0.05), Logistic regression analysis showed that abnormal menstruation, excessive menstrual flow, menstrual extension associated with the coking operating environment. There are many occupational harmful factors in the coking operation environment. Except for benzene (BSO) exceeding the foreign standards, other poisonous substances have not exceeded the standard.
