Statistical studies on the prognosis of anorexia nervosa

Statistical studies on the prognosis of anorexia nervosa were carried out by our research group. Subjects were 224 cases from 36 university hospitals throughout Japan. A questionnaire was mailed to each of the 224 patients in cooperation with their doctors. The outcome of 143 of the 224 cases was judged by their doctors as 'good' in 47 cases, 'intermediate' in 69 cases and 'poor' in 19 cases. 8 of the patients had died. The prognosis of typical cases was much poorer than that of atypical cases.
