Prenatal PCB-153 Exposure and Decreased Birth Weight: The Role of Gestational Weight Gain
نویسندگان
چکیده
Verner et al. (2013) recently questioned whether the association between cord levels of PCB-153 (poly chlorinated biphenyl-153) and birth weight reported in our recent metaanalysis (Govarts et al. 2012) might be attributable to the influence of gestational weight gain (GWG), a factor that may be related to both PCB-153 concentrations and birth weight. By using simulated data in a physiologically based pharmaco kinetic (PBPK) model, Verner et al. (2013) concluded that

Is the Relationship between Prenatal Exposure to PCB-153 and Decreased Birth Weight Attributable to Pharmacokinetics?
BACKGROUND A recent meta-analysis based on data from > 7,000 pregnancies reported an association between prenatal polychlorinated biphenyl (PCB)-153 exposure and reduced birth weight. Gestational weight gain, which is associated negatively with PCB levels in maternal and cord blood, and positively with birth weight, could substantially confound this association. OBJECTIVE We sought to estimat...

متن کاملPrenatal exposure to polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) may influence birth weight among infants in a Swedish cohort with background exposure: a cross-sectional study
BACKGROUND Prenatal exposure to persistent organic pollutants, e.g. polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) has been suggested to negatively affect birth weight although epidemiological evidence is still inconclusive. We investigated if prenatal exposure to PCBs and PBDEs is related to birth weight in a Swedish population with background exposure. METHODS B...
متن کاملBirth Weight and Prenatal Exposure to Polychlorinated Biphenyls (PCBs) and Dichlorodiphenyldichloroethylene (DDE): A Meta-analysis within 12 European Birth Cohorts
OBJECTIVES Exposure to high concentrations of persistent organochlorines may cause fetal toxicity, but the evidence at low exposure levels is limited. Large studies with substantial exposure contrasts and appropriate exposure assessment are warranted. Within the framework of the EU (European Union) ENRIECO (ENvironmental Health RIsks in European Birth Cohorts) and EU OBELIX (OBesogenic Endocrin...

Background and purpose: The newborn birth weight is an important indicator for prenatal care, general health and fetal viability. The aim of this study was to assess the relationship between pre-pregnancy BMÏ and pregnancy weight gain on neonatal birth weight. Materials and methods: Ïn a descriptive-analytical study, 16-40 years old pregnant mothers registered to prenatal clinics of Lowlagar...
