"Binge eating afflicts 3.5 percent of U.S. women and 2 percent of men at some point in their lives, according to a study by psychiatric researchers at Harvard University Medical School and its affiliate, McLean Psychiatric Hospital."
"It said about 0.9 percent of women and 0.3 percent of men reported suffering at some point from anorexia nervosa...It said 1.5 percent of women and 0.5 percent of men reported the condition of bulimia"
"Anorexia typically lasts 1.7 years, compared with 8.3 years for bulimia and 8.1 years for binge eating, the study said. "
(8 years for bulimia? Wow.)
