Epidemiological Investigation of Risk Factors of the Pregnant Women with Early Spontaneous Abortion in Beijing

Objective： To determine the risk factors of the pregnant women with early spontaneous abortion in Beijing. Methods： A total of 34,417 cases of pregnant women were participated in the survey from January 2000 to December 2013. A questionnaire was informed to each woman. The content of questionnaire includes four parts： general condition, obstetrical history, past history and family history, and living environment and habits. The mental condition was evaluated with Self-Rating Anxiety Scale（SAS） and Self-Rating Depression Scale（SDS）. Results： A total of 32,296 questionnaires were collected. The spontaneous abortion rate in the total sample was 3.0%. There was no significant difference between the normal pregnancy group and spontaneous abortion group in terms of general condition, obstetrical and past history（P〉0.05）. Significant differences between the two groups were found in terms of decoration during pregnancy, keeping pets, near mobile communication base station within 100 m around the residence, drinking during pregnancy, having a cold during pregnancy and SAS（P〈0.05）. Having a cold during pregnancy, decoration during pregnancy, near mobile communication base station within 100 m around the residence, keeping pets and high SAS were determined the independent risk factors of spontaneous abortion by Logistic regression analysis. Conclusions： Having a cold during pregnancy, decoration, keeping pets, near mobile communication base station within 100 m around the residence and high SAS are the independent risk factors of spontaneous abortion in Beijing.

农村育龄妇女自然流产危险因素流行病学研究

目的：探讨安徽省农村育龄妇女自然流产的危险因素。方法：采用随机整群抽样调查、单因素分析和Logistic回归分析。结果：安徽省农村育龄妇女1962~2001年间自然流产率达4.85%,明显高于全国平均水平3.60%。单因素分析显示,体重指数过高或过低、产前无检查、孕周检查过迟、多胎次、避孕失败、孕前吸烟或吃药、孕期吸烟或吃药均增加自然流产的危险性。Logistic回归分析得出高胎次（第2胎起）、服药避孕失败而怀孕、孕期吸烟、怀孕前近期吃药均增加自然流产的危险性。结论：该省农村妊娠妇女中并不存在特别的自然流产职业性危险因素,但进一步抓好计划生育、杜绝多胎生育、加强孕期保健等对降低自然流产率和促进妇女生殖健康是有利的。

育龄妇女早期自然流产危险因素的Logistic回归分析

目的:调查育龄妇女早期自然流产的危险因素,降低和预防自然流产的发生。方法:采用病例对照研究,用单因素和多因素Logistic回归分析探讨早期自然流产的危险因素。结果:单因素分析显示,男女双方学历、男女双方年龄、胎次与早期自然流产相关;多因素Logistic回归分析显示,女方学历、规律的妇科检查、男方年龄与早期自然流产相关。结论:女方学历、男方年龄是引起育龄妇女早期自然流产的危险因素,规律的妇科检查可降低自然流产的发生。
