Chemical Exposure in Pregnancy Tied to Birth Outcomes

JAMA Network

About The Study: This large cohort study of diverse U.S. pregnancies found widespread exposure to 10 classes of environmental chemicals, many of which were associated with differences in gestational age at birth or lower birth weight-for-gestational age z scores. These findings indicate that reducing gestational exposure to chemicals, particularly phthalates or alternative plasticizers and polycyclic aromatic hydrocarbons, could promote healthy deliveries and better child outcomes.
