A total of 142 consecutive patients cared for by child and adolescent psychiatry were followed up to the age of 33-37 years; 49% were treated in adult psychiatry between the ages of 20-25 years, and 20% of these were hospitalized. The frequency of hospitalization was 4-5 times that of a control group. Between the ages of 20-34 years, 32% were admitted some time for inpatient psychiatric care. Psychiatric diagnoses of the patients: schizophrenia 4%, manic-depressive 5%, neurosis and reactive insufficiency 11%, personality disorders and/or abuse diagnosis 12%. Patients with a schizophrenia diagnosis in adulthood needed the most hospitalization. The symptom picture was stable from child and adolescent psychiatric care through to adulthood, but abuse increased with age. The frequency of sick leave was 2.5 times higher among the child and adolescent psychiatric care patients than among the control group. At the age of 34-36 years, 13% of the former patients received disability benefits as compared with 1% for the same age groups in the entire population of Sweden. Twenty-one percent received sentences for criminal offenses from the age of 20-34 years. The number of crimes decreased with increasing age. Nearly 50% were in contact with the social welfare services, 3 times as many as in the control group. A third of the men completed their national military service. A total of 6 men and 1 woman died, indicating an increased mortality rate for men. All deaths except one were related to the mental disorder.
