VANCOUVER, British Columbia, May 5 (UPI) — African-American infants are at increased risk from prenatal tobacco smoke exposure, U.S. researchers found.
Researchers at Cincinnati Children’s Hospital Medical Center found it was the African-American children who were at increased risk from tobacco smoke exposure rather than the white infants.
“We found that low-level prenatal tobacco exposure was associated with deficits in both motor and cognitive development, but only for black children,” lead investigator Kimberly Yolton said in a statement.
Yolton and colleagues focused on the developmental differences between 242 white and black children at ages 1 and 2. They limited the study to children whose mothers had measurable levels of a biological byproduct of nicotine — cotinine — in their blood during pregnancy.
The study findings were presented at the annual meeting of the Pediatric Academic Societies in Vancouver.
