Abstract OBJECTIVE: To find the prevalence of somatoform disorders (SDs) among internal medical inpatients and to study the comorbidity with other psychiatric disorders. METHODS: Of 392 eligible consecutive medical inpatients, 294 (75\%) accepted to participate and, using a two-phase design, were assessed for ICD and DSM-IV somatoform diagnoses and for ICD-10 psychiatric diagnoses. RESULTS: A total of 18.1\% (95\% CI: 12.8-24.9\%) of the patients fulfilled the diagnostic criteria for an ICD-10 disorder, and 20.2\% (95\% CI:14.7-27.2\% ) for a DSM-IV SD. The prevalence of specified disorders revealed marked differences between the two diagnostic systems, e.g., concerning somatisation disorder (SD), which was more prevalent in the ICD-10 (5\%) than in the DSM-IV (1.5\%) equivalent. Quite the contrary was found in undifferentiated SD (0.7\% in ICD-10 and 10\% in DSM-IV). According to ICD-10 criteria, 3.5\% had hypochondriasis, 2.6\% a dissociative disorder, 3.2\% a somatoform autonomic dysfunction, 1.5\% had neurasthenia or persistent somatoform pain disorder, and 5\% had an SD, unspecified. SDs were more prevalent among younger females. Thirty-six percent of the patients with SDs also had another psychiatric disorder, 11\% a depression, and 25\% an anxiety disorder. The physicians detected about 1/3 of the cases. CONCLUSION: Somatoform disorders were prevalent among internal medical inpatients especially among younger women. Copyright 2004 Elsevier Inc.
