目的:了解407名孕妇经口接触全氟化合物的可能危险因素,探讨孕妇全氟化合物接触史与妊娠结局关系。方法:采用现状调查的方法,选取某地某医院产前诊断中心进行产检的孕妇作为研究对象,通过一对一访谈的方式,调查她们的饮食行为习惯,并对结果进行描述性统计。结果:所调查的407名孕妇经口接触全氟化合物的可能危险因素为:每天使用电饭锅或不粘锅烹饪(87.0%),饮用市售桶装水(68.8%),孕期吃鱼(≥1次/周)(66.8%)。结论:407名孕妇存在全氟化合物暴露风险的可能危险因素主要有使用电饭锅或者不粘锅烹饪和食用鱼类,建议孕妇在加强营养的同时应更加注意食品安全问题。
OBJECTIVE: To investigate the possible risk factors of oral exposure of perfluorocarbons in 407 pregnant women and explore the relationship between the exposure history of perfluorocompounds and pregnancy outcome in pregnant women. Methods: According to the status quo survey, pregnant women who took part in the prenatal diagnosis center of a hospital in a certain place were selected as the research object. Through one-on-one interviews, their dietary behaviors were investigated and the results were descriptively analyzed. RESULTS: The possible risk factors for oral exposure to perfluorocarbons for the 407 pregnant women surveyed were cooking daily (87.0%) with rice cookers or non-stick pots, drinking bottled water commercially available (68.8%) and eating fish during pregnancy ≥1 times / week) (66.8%). Conclusions: The potential risk factors for exposure of 407 pregnant women to perfluorinated compounds are mainly cooking or eating fish using rice cookers or nonstick cookware. It is suggested that pregnant women should pay more attention to food safety while strengthening nutrition.
