Maternal exposure to endocrine disruptors and placental transmission: a pilot study

Endocrine disruptors (EDs) are known to affect maternal and child health. The objective of our study was to identify the association between some of the most important endocrine-disruptive substances (perfluorooctane sulfonate [PFOS], perfluorooctanoic acid [PFOA], di2-ethylhexyl-phthalate [DEHP] and mono2-ethylhexyl-phthalate [MEHP]) and both pregnancy variability and birth outcomes. We measured the concentration of the EDs in maternal and cord blood samples of 29 mother–newborn pairs from the Pertini Hospital in Rome between March and June 2016. Each mother reported demographic, life style and diet information. We compared concentrations of the endocrine disruptors between mother and newborn, and among different molecules. We analyzed differences and trends of each ED substance according to the demography and diet information. PFOA levels in maternal blood showed a negative association with newborn weight. Concentration levels of PFOA in both maternal and cord blood of those with physiological p...
