About 4 in 10 high school students say they engaged in binge eating in the past month.
The Centers for Disease Control survey finds it's more common among girls, and among students who are Black, Hispanic or multiracial.
One adolescent medicine researcher tells STAT the findings are "extremely alarming."
This is the first time the survey asked about this eating disorder, which is defined as eating an unusually large amount of food in a short period of time and experiencing a loss of control. Health groups are calling on the CDC to include questions for teens about restrictive eating, such as dieting, fasting and purging. More data can lead to better treatment for eating disorders.
