北京某石化企业育龄妇女自然流产环境影响因素初步筛查

Preliminary Study on the Environmental Impact Factors of Spontaneous Abortion of Childbearing Age Women Worker in Petrochemical Works in Beijing 

为探讨北京某石化厂育龄女工自然流产的环境影响因素，选择首次妊娠为自然流产，且仅流产过一次的６１对２５～３０岁妇女及年龄和妊娠时间齐同的相应对照配对作为研究对象。对分析指标进行单因素卡方检验和Ｌｏｇｉｓｔｉｃ多因素回归分析。结果初步显示，嗜咸膳食（ＯＲ＝３．１７５，Ｐ＜０．０１）和接触职业毒物（ＯＲ＝２．７６１，Ｐ＜０．０５）为该地区妇女自然流产的主要危险因素；日常多吃蔬菜（ＯＲ＝０．４６８，Ｐ＜０．０５）和妊娠期乘车或骑自行车上班（ＯＲ＝０．４７４，Ｐ＜０．０５）为预防自然流产的保护因素，居住面积大（ＯＲ＝０．９３４，Ｐ＜０．０５）亦有一定影响，值得进一步深入研究。

In order to investigate the environmental impact factors of spontaneous abortion of the childbearing age women worker in petrochemical works in Beijing,61 cases with spontaneous abortion and 61 matched controls were interviewed(aged 25-30 years,same pregnancy stage and only 1 time abortion history)Monofactorial and multifactorial analyses were fitted by nonconditional logistic regression modelThe results showed that risk factors for saltovereating(OR=3175,P<001),and exposure to chemical toxicants(OR=2761,P<005) were the main risk factors for the spontaneous abortion; vegetableeating (OR=0468,P<005),and going to work by bicycle bus during pregnancy (OR=0474,P<005) and residental area for each person (OR=0934,P<005) were protective factors from the spontaneous abortionThese results were worthy for further study
