Regional differences in schizophrenia incidence in Denmark
Abstract:Objective:To examine the regional distribution of schizophrenia incidence in Denmark.
Method:A cohort consisting of 2441 Danish psychiatric patients, with first‐time admissions between January 1, 1978 and December 31, 1982, and diagnosed as having schizophrenia (ICD‐8) at least once in a 10‐year period of observation was divided into three regional groups by degree of urbanization.
Results:Incidence increased for both sexes with increasing urbanization. A diagnostic delay was most pronounced in the least urbanized areas and was most pronounced for women.
Conclusion:Our study confirms the existence of regional differences in schizophrenia incidence on a national basis. Marked regional differences in diagnostic delay were also demonstrated. A possible explanation could be regional differences in diagnostic procedures, underlining the importance of uniform diagnostic patterns as a means for reliable mapping of psychiatric morbidity and, hopefully, adequate treatment.
