How many people have Bulimia?
Incidence and prevalence rates for bulimia nervosa have been estimated at widely varying levels. Part of the problem in determining this is that many people with bulimia don’t report their symptoms and are treated only for the complications, with their prime condition never being diagnosed. At least two studies have indicated that only about one tenth of the cases of bulimia in the community are detected (Hoek 1995, and Ontario Health Survey, 1996). Other studies show that on average people with DSM IV classifiable bulimia nervosa have the disorder for 7.5 years before detection (Turnbull et al, 1996) The rate for bulimia nervosa seems to be growing steadily (Turnbull et al, and Hoek) particularly in young women. A study of Dutch data bases showed a one year prevalence rate to be 170 per 100,000 young females attending GPs, and an estimated rate of 1500 per 100,000 in the community (Hoek). International community studies have shown a lifetime prevalence for bulimia of 1.6% and for bing
