JCEM:妊娠期间全氟和多氟烷基物质浓度与产后健康

2020-07-06 MedSci原创 MedSci原创

妊娠期间EtFOSAA、PFOS和PFOA的浓度与不良的产后心脏代谢指标相关。

全氟烷基物质和多氟烷基物质(PFAS)是与体重增加和2型糖尿病相关的环境化学物质。近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,研究人员旨在评估妊娠期间PFAS血浆浓度与产后人体测量学和生物标记物之间相关的程度。

研究人员分析了1999-2002年间在Viva项目前瞻性队列中招募的并测量了血浆PFAS浓度的妇女,PFAS包括全氟辛烷磺酸(PFOS)、全氟辛酸(PFOA)和2-(N-乙基-全氟辛烷磺酰胺)乙酸(EtFOSAA)。786-801名妇女进行了三年产后人体测量,而761名妇女可进行了血压测量,450-454名妇女进行了血液生物标志物测定。研究人员使用多元回归分析评估了log2转化的PFAS与产后人体测量学指标、血压和血液生物标志物(瘦素、脂联素、性激素结合球蛋白[SHBG]、血红蛋白A1c [HbA1c]、白细胞介素6 [IL-6]、C反应蛋白[CRP]),并根据年龄、孕前BMI、婚姻状况、种族/民族、教育程度、收入、吸烟、产次和母乳喂养史进行了调整。

妊娠期间某些PFAS的浓度与肥胖率较高相关(例如,EtFOSAA每增加一倍,腰围增加0.4cm [95%CI:-0.1,0.9];PFOA中每增加一倍,上臂中部增大0.2cm [95%CI:-0.1,0.5];PFOS每增加一倍,肩下和三头肌皮褶的总厚度增加1.2mm [95%CI:0.1,2.2],而收缩压更高(例如,PFOS每增加一倍,血压升高1.2mmHg [95%CI:0.3,2.2])。EtFOSAA浓度越高,每增加一倍,IL-6浓度就升高10.8%(95%CI:3.3,18.9),而SHBG降低6.1%(95%CI:0.7,11.2)。

由此可见,妊娠期间EtFOSAA、PFOS和PFOA的浓度与不良的产后心脏代谢指标相关。
