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 possible ways of exposing perfluorocompounds (PFCs) to pregnant women during pregnancy and provide direction for further study on serum levels of perfluorinated compounds in pregnant women in early pregnancy. Methods: One-on-one interviews with pregnant women in obstetrics and gynecology clinics of a hospital in a certain place were conducted by using current research methods. The basic information, diet, lifestyle, activities and occupations of the study participants were obtained. EPI Data 3.02, Excel and SPSS Software such as data entry and statistical analysis. RESULTS: Among the 14 PFCs-related exposure items in the questionnaire, the top five exposure rates were: rice cooker cooked with non-stick cookware (87.4%), dairy products consumed daily (66.0%), , Weekly disposable paper food packaging materials (54.0%), weekly fish consumption (48.3%) and walking were the main outbound activities (43.4%). CONCLUSIONS: The exposure of pregnant women to perfluorinated compounds is mainly related to dietary behaviors, exposure to out-going activities followed by exposure to occupational exposure, and the proportion of occupational exposure to the study is small.
