Long-term stability of anorexia nervosa treatments: follow-up study of 218 patients.

We are reporting about the stability of n = 218 female in-patient treatments of Anorexia nervosa carried out at the University Clinic at Hamburg-Eppendorf from 1965 to 1979 mainly by a special program: introductory interview (with the family present), in-patient medical treatment (bed-rest, phenothiazines, tube-feeding), strict regimen and addressing the patients' conflict situation. The average interval between the end of therapy and the follow-up examination was 9.8 years. We were able to collect data about 93 per cent (n = 202) of the former patients concerning their somatic, psychological and psychosocial status. Based on these data we could assess 30 patients (14 per cent of our basic sample) as free of symptoms while 84 patients (39 per cent) presented slight symptoms so that 53 per cent of the former patients could exercise their profession without being considerably handicapped and able to keep up a relationship with a partner. On the other hand, 39 patients (18 per cent) still showed marked symptoms at follow-up and with 19 patients (9 per cent) there were manifestations of severe or extreme symptoms. Thirty former patients (14 per cent) had died with the mortality rate distinctly increasing over the years. Possible interpretations of our results and consequences for therapy are presented.
