Comorbidity in an inpatient eating disordered population: clinical characteristics and treatment implications.
Data are presented that describe the clinical characteristics of 96 patients treated at the C.F. Menninger Memorial Hospital, Topeka, Kansas, from November 1983 to June 1989. Their Axis I eating disorder diagnoses were as follows: 53 had diagnoses of bulimia; 21 had anorexia nervosa; 2 had both diagnoses; 17 had atypical disorders or eating disorders not otherwise specified; and 2 had a diagnosis of psychological factors affecting physical conditions. Seventy-three percent of the cohort were found to have either Axis I or Axis II disorders or both, comorbidity. Borderline personality disorder was found in 46% of the sample, although 20% of the patients with borderline disorders were diagnosed retrospectively. Depression was the largest comorbid Axis I diagnosis. Patient variables for sexual abuse, drug and alcohol addiction, purgative behaviors, and interpersonal relationships are also described. The authors conclude that a substantial subpopulation of eating disordered patients are significantly comorbid for other psychiatric illnesses. This high incidence of comorbidity may help explain the frequency of refractoriness of many eating disordered patients who do not respond to outpatient or short-term inpatient hospitalization. The authors recommend that additional research studies address the problems of the comorbid eating disordered patient and suggest that the findings be taken into account by clinicians and payers.
