Association of urinary concentrations of early pregnancy phthalate metabolites and bisphenol A with length of gestation

摘要

BackgroundEnvironmental exposure to phthalates and bisphenol A (BPA) may have endocrine disrupting effects that alter length of gestation. We assessed the association between the urinary concentrations of 11 phthalate metabolites and BPA with length of gestation in a cohort of women followed from before conception with daily 1st-morning urinary hormone measures that identified day of implantation.
