摘要
目的探讨导致早期自然流产的危险因素,研究电磁辐射暴露与早期自然流产的关系。方法采用非配对病例对照研究,对120名临床确诊为自然流产且孕周≤12周的孕妇(病例组)及363名妊娠12周经临床确诊为正常妊娠的孕妇(对照组)就家居环境及电磁辐射暴露情况进行问卷调查。抽取有代表性的家庭进行室内、室外家居环境及家用电器的电磁场检测。结果单因素分析中,病例组看电视时间>15 h/周、使用电脑时间>10 h/周、电磁炉、手机使用时间>20 min/d、居住地周围有电磁辐射设备的比例高于对照组(P<0.05);而在多因素分析中,使用电脑时间>10 h/周、使用电磁炉、手机时间>20 min/d、年龄>30岁、有不良孕产史及被动吸烟是自然流产的危险性因素。结论妊娠期经常使用电脑、手机、电磁炉可能与早期自然流产的发生有关联。
Objective To investigate the association between electromagnetic radiation and spontaneous abortion and to identify the risk factors of spontaneous abortion. Methods A case-control study was conducted. The cases （n=120） were the pregnant women of no more than 12 weeks with spontaneous abortion, recruited at the Peking Union Medical College Hospital. The controls （n=363） were the pregnant women with normal pregnancy of 12 weeks. The house environmental electromagnetic radiation exposure was matured. Results The proportion of watching TV〉15 h per week, operating computer〉10 h per week , using the mobile phones〉20 min per day, induction cooker and electromagnetic equipment near the dwell in the cases were significantly higher than those in the controls in single factor analysis （P〈0.05）; In multifactors Logistic regression analysis, operating computer 〉10 h per week ,using the mobile phones〉20 min per day ,using induction cooker frequently, abnormal pregnanc history, passive smoking during pregnancy and over 30 years old were associated with risk of spontaneous abortion. Conclusion Using the computer, mobile phones, induction cooker often during pregnancy may be involved in spontaneous abortion.
