对长春市纺织工业系统的三家工厂中接触不同声强级稳态噪声的已婚女工879人,进行回顾性及现状职业流行病学调查。结果表明,接触噪声前后,月经功能异常率有非常显著差异;好高症、自然流产、早产及低体重儿的发生率有增高趋势,但差异不显著;高声强级组有2例出生缺陷,对照组及中声强级组则无;乳汁分配不足及过少阳性率则随声强级增加而增高(P<0.05);接触组子代智商明显低于对照组(P<0.05)。
879 married women workers exposed to steady-state noise of different sound intensity levels in three factories of the textile industrial system of Changchun City were retrospectively reviewed and their current occupational epidemiological survey was conducted. The results showed that there was a significant difference in the abnormal menstruation before and after the exposure to noise. The incidence of hyperhidrosis, spontaneous abortion, premature birth and low birth weight children tended to increase, but the difference was not significant. There were 2 birth defects (P <0.05). The IQ of the offspring of contact group was significantly lower than that of the control group (P <0.05).
