概括

这项研究没有发现PFAS化学物质暴露与无孕妇女流产之间的明显联系. 需要进一步的研究来了解影响怀孕结果的环境因素.

科学领域:

生殖流行病学生殖流行病学
环境健康环境健康
毒理学毒理学毒理学

背景情况:

流产影响了大约15%的已知的怀孕,很少有可改变的原因.
和多醇基物质 (PFAS) 是可以干扰生殖途径的环境污染物.
PFAS暴露与人类流产风险之间的关联尚不清楚.

研究的目的:

调查各种PFAS的血度与最近流产的发生之间的关系.
评估PFAS混合物对流产风险的影响.

主要方法:

在挪威的母亲,父亲和儿童队列研究 (MoBa) 中进行了一项嵌套病例控制研究.
血PFAS水平 (PFHxS,PFHpS,PFOS,PFOA,PFNA,PFDA,PFUnDA) 测量了2525名没有孕妇的妇女.
后勤回归和基于量子的g计算被用来分析与最近流产的关联,调整混因素.

主要成果:

在单个PFAS度或整体PFAS混合物和最近流产之间没有观察到显著的关联.
随着PFAS水平的增加,流产的几率比率没有显著变化 (OR 0.95;95%CI:每四分位数增加0.83-1.09).
对BMI,月经周期和口服避孕药的调整没有改变零结果.

结论:

这项研究没有发现PFAS度与无孕妇女流产之间的明显关联.
这些发现表明,PFAS可能不是这一群体中流产的重要直接风险因素.
对环境暴露和流产的进一步调查是合理的.

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
