摘要
目的 研究噪声对女工生殖机能、妊娠结局的影响。方法 应用回顾性队列研究方法 ,对接触噪声强度在85 0 0～ 10 3 5 0dB(A)的女工进行了队列观察 30年。结果 噪声作业女工月经功能紊乱 (47 5 6 % ,RR =2 79)、痛经(11 71% ,RR =1 80 )、自然流产 (6 5 2 % ,RR =11 44)患病率明显高于对照组 ,而早产、难产、死胎死产、先天畸形、低体重儿等观察指标虽然未见明显的影响 ,但其发生率有随接触声级增强而增高的趋势。结论 噪声对女工生殖机能、妊娠结局有影响。
Objective To study the effects of noise on female's reproductive function and pregnant outcomes.Methods A 30 year long retrospective cohort study on 1 640 female workers exposed to the noise between 85.00-103.50 dB(A) had been studied.Results The rate of menstrual disorders (47.56%, RR=2.79), dysmenorrhoea(11.71%, RR=1.80), spontaneous abortion(6.52%, RR=11.44) in exposed group appeared to be significantly higher than that in control group. However, no significant difference for the incidences of adverse pregnant outcome(premature birth, dystocia, still birth, congenital defect, lower birth weight) was shown between two groups. Conclusion Noise might be harmful to the reproductive function and the pregnant outcomes of female workers.
