title: Gender and schizophrenia: age at onset and sociodemographic attributes.
abstract: A consecutive series of 214 patients (125 males, 89 females) who met the Research Diagnostic Criteria for schizophrenia were studied to determine gender differences in age at onset of the illness and sociodemographic attributes. The immediate family's first awareness of psychotic symptoms or signs and age at first presentation in hospital were used as indices of onset; male patients had a significantly earlier age of onset than females. By the time they were 30 years of age, 83% of male patients had already become ill and only 66% of females had done so. Significantly more females than males were married at the time of first contact with hospital. Married males did not differ from married females in age at onset of illness, suggesting that patients who marry may have late onset.
