摘要
Objective:To study the association of environmental adverse factors with early embryo loss,and explore the possible risk factors in daily life. Methods:A questionnaire was administered to 93 new cases of embryo loss(case group) collected in four general hospitals in Tianjin from April 2007 to April 2008 and 93 matched cases of induced abortion(control group) in normal pregnant women who sought the abortion by other reasons.The questionnaire covered information on parental exposure to various environmental factors during and before pregnancy,and the information on daily life.Data were analyzed by single-factor analysis,multiple linear regression and logistic regression analysis.Possible risk factors were identified and odds ratio calculated. Results:Cooking frequently during pregnancy,more daily traffic hours,and decoration history in early pregnancy and paternal exposure to toxic matters three months before pregnancy were associated with early embryo loss, while maternal education was a protective factor. Conclusion:Women exposed to the harmful substances from traffic emissions,cooking and decoration could be at an increased risk of early embryo loss.
