Fifty seven female workers at mean age 32 years (range, 23-45 years), employed in a storage battery plant and a capacitor factory were investigated. The lead exposure period was 7.4 years (range, 1-17 years). The retrospective method was used to analyse reproductive functions of women: menses, libido, abortion and delivery. The results were compared with the control group (62 female workers, mean age 32 years; range, 24-45 years). The incidence of polymenorrhea, prolonged and abnormal menstruations, hypermenorrhea was significantly higher in the lead exposed group than in controls. The incidence of spontaneous abortions was reported by 6 exposed female workers whereas it was not observed in the control group (p = 0.01). The authors conclude that occupational lead exposure of female workers could lead to the impairment of the functions of reproductive system, however poor working conditions and workload may prove to be additional factors responsible for functional disorders in the subjects under study.
对一家蓄电池厂和一家电容器厂的57名平均年龄为32岁(范围为23 - 45岁)的女工进行了调查。铅暴露时间为7.4年(范围为1 - 17年)。采用回顾性方法分析女性的生殖功能:月经、性欲、流产和分娩情况。将结果与对照组(62名女工,平均年龄32岁;范围为24 - 45岁)进行比较。铅暴露组中月经过多、经期延长和异常、月经过多的发生率显著高于对照组。6名暴露女工报告有自然流产情况,而对照组未观察到(p = 0.01)。作者得出结论,女工的职业性铅暴露可能导致生殖系统功能受损,然而恶劣的工作条件和工作量可能是导致所研究对象功能障碍的额外因素。
