Perfluoroalkyl substances in umbilical cord serum and gestational and postnatal growth in a Chinese birth cohort
Abstract
Although animal studies have found that perfluoroalkyl substances (PFASs) affect gestational and postnatal growth, the epidemiological findings are limited and not in agreement. We explored the associations of PFAS concentrations in umbilical cord blood with gestational and postnatal growth in China. Three hundred thirty-seven singleton newborns and their mothers were recruited from November 2013 to December 2015 in Zhoukou City, China. Umbilical cord blood was collected to measure eleven PFASs by liquid chromatography-mass spectrometry. The index of gestational and postnatal growth contained fetal weight, length, and head circumference. These were obtained at birth and at the follow-up investigation (mean 19 months). Exposed to higher perfluorooctanoic acid (PFOA) were connected with reduced length at birth (p for trend = 0.01) and decreased postnatal weight (β = -429.2 g; 95% CI: -858.4, -0.121 for 2nd VS. 1st). Exposed to perfluoroundecanoic acid (PFUdA) were positively associated with indications of gestational growth and postnatal growth (p for trend = 0.02 for birth length; p for trend = 0.04 for postnatal length). Exposed to higher perfluorododecanoic acid (PFDoA) were associated with lower birth weight (β = -122.9 g, 95% CI: -244.7 to -1.2 for 2nd VS. 1st), but higher postnatal length (p for trend = 0.03). Neonates in the highest exposure group of per-fluorohexanesulfonate (PFHxS) showed decreased birth length (β = -0.33 cm, 95% CI: -0.68 to -0.01, for 2nd VS. 1st), b…

Epidemiological studies indicate that prenatal and/or in utero exposure to PFAS is associated with reductions in birth weight, birth length, and head circumference.
“A mounting body of epidemiological investigations underscored that prenatal and/or in utero exposure to PFAS was associated with the reduction of BW, BL and HC (Chu et al., 2020; Cao et al., 2018; Li et al., 2017; Chang et al., 2022; Chen et al., 2021; Ji et al., 2023; Kashino et al., 2020; Ku et al., 2022; Lee et al., 2016; Marks et al., 2021; Marks et al., 2019; Padula et al., 2023; Sagiv et al.”

PFAS can cross the placental barrier, as shown by their detection in cord blood samples from newborns.
“Alarmingly, PFAS can cross the placental barrier, as revealed by their ubiquitous detection in cord blood samples from newborns (Cao et al., 2018; Hall et al., 2022; Li et al., 2017; Mahfouz et al., 2023; Manea et al., 2020).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
