The past year's crop of follow-up and outcome studies tends to confirm
prevailing opinion. Investigators working with hospitalized anorexia
nervosa sufferers found that many sufferers continue to suffer from ea
ting disorders, even after several years. There is, however, a tendenc
y to move toward bulimia nervosa and partial syndromes as opposed to n
oneating diagnoses. Sufferers from bulimia nervosa rarely go on to dev
elop anorexia nervosa. Nevertheless, a need for good follow-up data on
population-based samples and treatment trials remains.
