BACKGROUND Longitudinal trends in per- and polyfluoroalkyl substances (PFAS) serum concentrations across pregnancy have not been thoroughly examined, despite evidence linking prenatal PFAS exposures with adverse birth outcomes. OBJECTIVES We sought to characterize longitudinal PFAS concentrations across pregnancy and to examine the maternal-fetal transfer ratio among participants in a study of risk and protective factors for adverse birth outcomes among African Americans. METHODS In the Atlanta African American Maternal-Child cohort (2014-2020), we quantified serum concentrations of four PFAS in 376 participants and an additional eight PFAS in a subset of 301 participants during early (8-14 weeks gestation) and late pregnancy (24-30 weeks gestation). Among these, PFAS concentrations were also measured among 199 newborns with available dried blood spot (DBS) samples. We characterized the patterns, variability, and associations in PFAS concentrations at different time points across pregnancy using intraclass correlation coefficients (ICCs), maternal-newborn pairs transfer ratios, linear mixed effect models, and multivariable linear regression, adjusting for socioeconomic and prenatal predictors. RESULTS Perfluorohexane sulfonic acid (PFHxS), perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA) were detected in >95% of maternal samples, with PFHxS and PFOS having the highest median concentrations. We observed high variability in PFAS concentrations across pregnancy time points (ICC=0.03-0.59). All median PFAS concentrations increased from early to late pregnancy, except for PFOA and N-methyl perfluorooctane sulfonamido acetic acid (NMFOSAA), which decreased [paired t-test for all PFAS p<0.05 except for PFOA and perfluorobutane sulfonic acid (PFBS)]. Prenatal serum PFAS were weakly to moderately correlated with newborn DBS PFAS (-0.05

亚特兰大非裔美国母婴队列中从怀孕早期到分娩的全氟烷基和多氟烷基物质的前瞻性分析。



背景 尽管有证据表明产前 PFAS 暴露与不良分娩结局有关,但尚未彻底检查整个怀孕期间全氟烷基和多氟烷基物质 (PFAS) 血清浓度的纵向趋势。目的 我们试图描述整个怀孕期间的纵向 PFAS 浓度,并检查非裔美国人不良分娩结局的风险和保护因素研究中参与者的母胎转移比率。方法 在亚特兰大非裔美国人母婴队列 (2014-2020) 中,我们量化了 376 名参与者的 4 种 PFAS 血清浓度和 301 名参与者的另外 8 种 PFAS 的血清浓度妊娠早期 (妊娠 8-14 周) 和妊娠晚期 (妊娠 24-30 周)。其中,还测量了 199 名具有可用干血斑 (DBS) 样本的新生儿的 PFAS 浓度。我们使用类内相关系数 (ICCs) 、母婴对转移比、线性混合效应模型和多变量线性回归来表征妊娠不同时间点 PFAS 浓度的模式、变异性和关联,并调整了社会经济和产前预测因子。结果 在 >95% 的母体样本中检测到全氟己烷磺酸 (PFHxS) 、全氟辛烷磺酸 (PFOS) 和全氟壬酸 (PFNA),其中 PFHxS 和 PFOS 的中位浓度最高。我们观察到 PFAS 浓度在不同妊娠时间点的显著变化 (ICC=0.03-0.59)。所有 PFAS 浓度中位数从妊娠早期到晚期均有所增加,但 PFOA 和 N-甲基全氟辛烷磺胺基乙酸 (NMFOSAA) 除外 [所有 PFAS p<0 的配对 t 检验。05 PFOA 和全氟丁烷磺酸 (PFBS) 除外]。产前血清 PFAS 与新生儿 DBS PFAS 呈弱至中度相关 (-0.05
