(ABCNEWS.GO) — Older and more educated women are more likely to drink alcohol during pregnancy, according to a new Centers for Disease Control and Prevention study published Friday.

About one in 13 women drink while pregnant, according to the study, and out of those women, one in four reportedly binge drink.

The researchers examined more than 340,000 self-reported surveys that were a part of the Behavioral Risk Factor Surveillance System of data from women between the ages of 18 and 44.
