INCIDENCE OF EATING DISORDERS IN PSYCHIATRIC-HOSPITALS AND WARDS IN DENMARK, 1970-1993

Two previous studies in Denmark found diverging results in analyzing t rends in new cases of eating disorders in the psychiatric in- and day- patient services, although the same data source, the nationwide Danish Psychiatric Case Register, was used. The present study - also using i nformation from the nationwide Danish Psychiatric Case Register, but c orrecting for several register biases - confirms a highly significant increase in new cases of eating disorders in psychiatric hospitals and wards. The increase is seen exclusively in younger females. The diver ging results in the previously mentioned studies in Denmark may be asc ribed to methodological issues.
