esearchers at Duke Medicine and the University of North Carolina School of Medicine were surprised to find that in a study of 1,420 children, those who bullied others were twice as likely to display symptoms of bulimia, such as bingeing and purging, when compared to children who are not involved in bullying. The findings are published in the December issue of International Journal of Eating Disorders.
"For a long time, there's been this story about bullies that they're a little more hale and hearty," said lead author William Copeland, Ph.D., associate professor of psychiatry and behavioral sciences at Duke University School of Medicine. "Maybe they're good at manipulating social situations or getting out of trouble, but in this one area it seems that's not the case at all. Maybe teasing others may sensitize them to their own body image issues, or afterward, they have regret for their actions that results in these symptoms like binge eating followed by purging or excess exercise."
