The Relationship of Phthalate Exposure During Pregnancy and Preeclampsia
Study Details
Study Description
Brief Summary
Phthalates are a group of ubiquitous synthetic endocrine-disrupting chemicals. Fetal and neonatal periods are particularly susceptible to endocrine disorders, which prenatal exposure to phthalates causes. There is increasing evidence concerning the potential endocrine disrupting for phthalate exposure during pregnancy. Prenatal exposure phthalates would disrupt the level of sex hormone in pregnant women, which results in preeclampsia. The relationship of prenatal phthalate exposure with maternal and neonatal outcomes in human beings was often sex-specific associations. Because of the potentially harmful influence of prenatal phthalate exposure, steps should be taken to prevent or reduce phthalate exposure during pregnancy.
