Abstract

Age at onset was determined in a sample of 360 patients representative of the 8069 schizophrenics hospitalised in SR Croatia. The 95% confidence interval for mean age at onset was 22.9–26.7 years. The difference between males and females was not significant, unlike the age difference between the sexes reported for age at first admission for schizophrenia. Results may be influenced by attrition of the original population of patients.
