选择电镀和皮革厂58名作业女工及95名对照组女工进行生直流行病学调查．结果表明，接触组女工的月经异常率（18.96％）和痛经发生率（46.55％）显著高于对照组（6．32％，P＜0．05；3．16％，P＜0．01）。接触组的经期异常和经量增多也高于对照组，但无统计学意义．接触组的妊娠合并症（13．51％）高于对照组（9．10％，P＞0．05），无统计学意义。接触组异常妊娠结局，死产和自然流产发生率分别为4．05％和13．51％，显著高于对照组（0和5.17％，P＜0．05），接触组和对照组早产的比值比（OR）也大于1，提示铬对作业女工的生殖功能可能存在不良影响．
58 workers in the electroplating and tannery and 95 women in the control group were selected for direct-to-health epidemiological survey. The results showed that the abnormal menstruation rate (18.96%) and dysmenorrhea incidence rate (46.55%) in the exposed group were significantly higher than those in the control group (6.32%, P <0.05; 3.16%, P <0.01) . The contact group’s menstrual abnormalities and the amount of increase also higher than the control group, but not statistically significant. Pregnancy complications (13.51%) in the exposure group were significantly higher than those in the control group (9.10%, P> 0.05). There was no statistical significance. The incidence of abnormal pregnancy outcomes, stillbirth and spontaneous abortion in the contact group were 4.05% and 13.51%, respectively, which were significantly higher than those in the control group (0 and 5.17%, P <0.05) The odds ratio (OR) was also greater than 1, suggesting that chromium may have an adverse effect on the reproductive function of working women.
