SEATTLE -- A new study by University of Washington Medicine found there is no safe level of alcohol consumption by women who are pregnant.
The study, published Wednesday in Advances of Pediatric Research, found that the risk of damage to a fetus from alcohol isn't solely dependent on how much a mother drinks during pregnancy.
The genetics of a fetus also comes into play, the study found.
Researchers looked at 48 pairs of twins, over a 26-year period who were exposed to the same amount of alcohol during pregnancy.
They found that while identical twins with identical DNA experienced the same fetal alcohol outcomes, fraternal twins often had different fetal alcohol outcomes, said Susan Astley Hemingway, lead author on the study and a professor of pediatrics at the University of Washington School of Medicine.
“Sometimes the results were strikingly different, with one being born with severe fetal alcohol syndrome while the other was only mildly affected,” Hemingway wrote in a news release announcing the study. “Given that, the only safe level of alcohol consumption for a mother during pregnancy is none at all.”
