摘要
目的：研究职业性噪声接触与女工发生早产之间的关系。方法收集1985—2012年国内公开发表的关于职业性噪声接触与女工发生早产有关的文献，严格按照纳入和剔除标准筛选接触稳态噪声的文献。根据噪声接触强度将女工分为85-89 dB（A）组、90-99 dB（A）组、100-115 dB（A）组和对照组。采用Review Manager 4.2软件进行Meta分析，计算合并的相对危险度（ RR）值及其95％可信区间（ CI）。结果19篇文献纳入Meta分析。85-89 dB（A）组女工早产发生率和对照组差异无统计学意义[RR=1.13，95%CI为（0.85-1.50），P〉0.05]；90-99 dB（A）组和100-115 dB（A）组女工早产的发生率均高于对照组[RR分别为1.71和1.94，95%CI分别为（1.18-2.480和（1.61-2.33），P〉0.05]。结论孕期接触职业噪声≥90 dB（A）时，女工发生早产的风险增加。
Objective To analyze the correlation between occupational noise exposure and women premature delivery. Methods The domestic publication literature about occupational noise exposure and women premature delivery from 1985 to 2012 were collected. According to the inclusion and exclusion standard,literatures of occupational steady-state noise expo-sure were selected strictly. Based on the levels of steady-state noise exposure,female workers were sorted into 85-89 dB（ A） group,90-99 dB（ A）group,100-115 dB（ A）group and control group. Meta analysis was carried out with Review Manager 4.2 software. Pooled relative risk（RR）and 95% confidence intervals（CI）were calculated as well. Results Nineteen domestic publication literatures were included in the Meta analysis. Compared with the control group,the premature delivery rate in 85-89 dB（A）group was no statistical significant difference（RR=1. 13,95%CI：0. 85-1. 50,P＆gt;0. 05）,but the premature delivery rates both in 90-99 dB（ A）group and 90-99 dB（ A）group were significantly increase respectively（ RR=1. 71,95%CI：1. 18-2. 48,P〉0. 01;RR=1. 94,95%CI：1. 61-2. 33,P〉0. 01）. Conclusion Prenatal exposure to occu-pational noise of 90 dB（ A）or higher could lead to an increased risk of premature delivery in female workers.
