A study of 300 African-American and Dominican Republic children living in New York City exposed to acetaminophen prenatally determined they were more likely to have asthma symptoms at age five. Building on prior research showing an association between both prenatal and postnatal acetaminophen and asthma, this is the first study to demonstrate a direct link between asthma and an ability to detoxify foreign substances in the body. The study was conducted by the Columbia Center for Children’s Environmental Health at Columbia University’s Mailman School of Public Health and the findings were published in the journal Thorax.
