Exposure to chemicals during fetal development has been shown to increase the risk of adverse health consequences, including preterm birth and birth defects, childhood morbidity, and adult disease and mortality according to the research team. In addition, chemicals can cross the placenta and enter the fetus, and in other studies, a number of chemicals measured in maternal urine and serum have been found in amniotic fluid, cord blood and meconium, they state.
The researchers analyzed data for 268 pregnant women from the National Health and Nutritional Examination Survey (NHANES) 2003-2004, a nationally representative sample of the U.S. population.
"Our findings indicate several courses of action. First, additional research is needed to identify dominant sources of exposure to chemicals and how they influence our health, especially in reproduction," said Woodruff. "Second, while individuals can take actions in their everyday lives to protect themselves from toxins, significant, long-lasting change only will result from a systemic approach that includes proactive government policies."
