BACKGROUND Per- and polyfluoroalkyl substances (PFAS) are widespread persistent organic pollutants and endocrine disruptors. High doses of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) exposure can cause pregnancy loss and infant deaths in animals, but the associations between PFAS exposures and risk of miscarriage in humans are not well studied. METHODS Using a case-control study nested within the Danish National Birth Cohort (DNBC, 1996-2002), we compared 220 pregnancies ending in miscarriage during weeks 12-22 of gestation, with 218 pregnancies resulting in live births. Levels of seven types of PFAS [PFOS, PFOA, perfluorohexane sulfonate (PFHxS), perfluoroheptane sulfonate (PFHpS), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), and perfluorooctanesulfonic acid (PFOSA)] were measured in maternal plasma collected in early gestation (mean gestational week 8). We estimated the odds ratios (ORs) and 95% confidence intervals (CIs) for miscarriage and each PFAS as a continuous variable or in quartiles, controlling for maternal age, parity, socio-occupational status, smoking and alcohol intake, gestational week of blood sampling, and maternal history of miscarriage. Stratification by parity and PFAS mixture analyses using weighted quantile sum (WQS) regression were also conducted. RESULTS We observed a monotonic increase in odds for miscarriage associated with increasing PFOA and PFHpS levels. The ORs comparing the highest PFOA or PFHpS quartile to the lowest were 2.2 (95% CI: 1.2, 3.9) and 1.8 (95% CI: 1.0, 3.2). The ORs were also elevated for the second or third quartile of PFHxS or PFOS, but no consistent exposure-outcome pattern emerged. An interquartile range (IQR) increment in the WQS index of seven PFAS was associated with 64% higher odds for miscarriage (95% CI: 1.15, 2.34). The associations were stronger in parous women, while findings were inconsistent among nulliparous women. CONCLUSION Maternal exposures to higher levels of PFOA, PFHpS, and PFAS mixtures were associated with the risk of miscarriage and particularly among parous women. Larger replication studies among nulliparous women are needed to allay concerns about confounding by reproductive history. https://doi.org/10.1289/EHP6202.

母体血浆全氟烷基物质和流产:丹麦全国出生队列中的嵌套病例对照研究。

背景全氟和多氟烷基物质 (PFAS) 是广泛存在的持久性有机污染物和内分泌干扰物。高剂量的全氟辛烷磺酸 (PFOS) 和全氟辛酸 (PFOA) 暴露可导致动物流产和婴儿死亡,但 PFAS 暴露与人类流产风险之间的关联尚未得到充分研究。方法 使用嵌套在丹麦国家出生队列 (DNBC,1996-2002) 中的病例对照研究,我们比较了 220 例在妊娠第 12-22 周以流产结束的妊娠,其中 218 例妊娠导致活产。七种 PFAS [PFOS、PFOA、全氟己烷磺酸 (PFHxS)、全氟庚烷磺酸 (PFHpS)、全氟壬酸 (PFNA)、全氟癸酸 (PFDA)、和全氟辛烷磺酸 (PFOSA)] 在妊娠早期(平均妊娠第 8 周)收集的母体血浆中进行测量。我们将流产和每个 PFAS 的比值比 (OR) 和 95% 置信区间 (CI) 估计为连续变量或四分位数,控制了母亲的年龄、产次、社会职业地位、吸烟和酒精摄入量、妊娠周血抽样,以及母亲流产史。还进行了使用加权分位数总和 (WQS) 回归的奇偶分层和 PFAS 混合分析。结果 我们观察到与 PFOA 和 PFHpS 水平增加相关的流产几率单调增加。比较最高 PFOA 或 PFHpS 四分位数与最低四分位数的 OR 分别为 2.2(95% CI:1.2、3.9)和 1.8(95% CI:1.0、3.2)。全氟己烷磺酸或全氟辛烷磺酸的第二或第三四分位数的 OR 值也有所升高,但没有出现一致的暴露结果模式。七个 PFAS 的 WQS 指数的四分位间距 (IQR) 增量与流产几率增加 64% 相关(95% CI:1.15、2.34)。这种关联在经产妇女中更强,而在未生育妇女中的研究结果不一致。结论 母亲暴露于较高水平的 PFOA、PFHpS 和 PFAS 混合物与流产风险相关,尤其是在经产妇女中。需要对未生育妇女进行更大规模的复制研究,以减轻对生育史混淆的担忧。https://doi.org/10.1289/EHP6202。七个 PFAS 的 WQS 指数的四分位间距 (IQR) 增量与流产几率增加 64% 相关(95% CI:1.15、2.34)。这种关联在经产妇女中更强,而在未生育妇女中的研究结果不一致。结论 母亲暴露于较高水平的 PFOA、PFHpS 和 PFAS 混合物与流产风险相关,尤其是在经产妇女中。需要对未生育妇女进行更大规模的复制研究,以减轻对生育史混淆的担忧。https://doi.org/10.1289/EHP6202。七个 PFAS 的 WQS 指数的四分位间距 (IQR) 增量与流产几率增加 64% 相关(95% CI:1.15、2.34)。这种关联在经产妇女中更强,而在未生育妇女中的研究结果不一致。结论 母亲暴露于较高水平的 PFOA、PFHpS 和 PFAS 混合物与流产风险相关,尤其是在经产妇女中。需要对未生育妇女进行更大规模的复制研究,以减轻对生育史混淆的担忧。https://doi.org/10.1289/EHP6202。PFAS 混合物与流产风险有关,尤其是在经产妇女中。需要对未生育妇女进行更大规模的复制研究,以减轻对生育史混淆的担忧。https://doi.org/10.1289/EHP6202。PFAS 混合物与流产风险有关,尤其是在经产妇女中。需要对未生育妇女进行更大规模的复制研究,以减轻对生育史混淆的担忧。https://doi.org/10.1289/EHP6202。
