483名孕期妇女全氟化合物暴露途径的调查

Investigation on 483 pregnant women 's exposed pathways of perfluorinated compounds

目的:探讨孕期妇女对全氟化合物(PFCs)暴露的可能途径,为深入研究孕早期妇女全氟化合物血清负荷水平提供方向。方法:采用现况研究方式对某地某医院产科门诊孕妇进行一对一访谈,获取研究对象的基本信息、饮食习惯、生活方式、活动场所及职业相关情况等,应用EPI Data 3.02、Excel和SPSS等软件进行资料的录入与统计分析。结果:调查问卷的14条PFCs相关暴露条目中,显示暴露发生率前5位分别是:每天所食饭菜为电饭锅或不粘锅烹制(87.4%)、每天食用乳制品(66.0%)、每周使用一次性纸质食品包装材料(54.0%)、每周食用鱼类(48.3%)和步行等为主要外出活动方式(43.4%)。结论:孕妇暴露于全氟化合物的途径主要与饮食行为有关,外出活动方式的暴露率次之,职业暴露在研究中所占比例较小。

Objective ： To explore the pregnant women＇s exposed pathways of perfluorinated compounds （PFCs） and provide direc- tion for further research on early pregnant women of perfluorinated compounds in serum. Methods： A cross - sectional study of pregnant women in an obstetrics clinic was one - on - one interviews to access to the informations about objects ： the basic information, diet, lifestyle, surrounding of activity and occupation related situation. EPI Data 3.02, Excel and SPSS softwares were used for entry and statistical analysis of data. Results： To eat meals cooked by electric rice cooker or non - stick eookware every day, to eat dairy products every day, to consume disposable paper food packaging materials every week, to eat fish every week and walking as the main traffic mode were the top 5 most com- mon exposed pathways, with the incidence rate of 87.4%, 66. 0%, 54. 0%, 48.3% and 43.4%, respectively, among 14 exposed path- ways of the questionnaire. Conclusion： Exposure of pregnant women to perfluorinated compounds is mainly associated with dietary behavior, then traffic mode and occupational exposure.
