“…In our study we showed that the disease started in females approximately four years later than in males. This finding was consistent with the information that schizophrenia started earlier in males [16][17][18] . We did not find any gender difference in the subtypes of schizophrenia and this finding was consistent with other studies 16,19 .…”

“…This finding was consistent with the information that schizophrenia started earlier in males [16][17][18] . We did not find any gender difference in the subtypes of schizophrenia and this finding was consistent with other studies 16,19 . Despite socio-cultural differences, the fact that the onset age of schizophrenia was four years higher in the women than in men and that the rates of the schizophrenia subtypes were consistent with those detected in the other studies demonstrates that these rates were determined by neurobiological mechanisms rather than socio-cultural factors.…”

TURKEYABSTRACT -Background and Objectives: This study was designed to investigate the association of the gender and subtype diagnosis with the onset age of the disease, marriage, reproductive rates in the schizophrenic inpatients.Methods: Total of 463 patients (329 males and 134 females) hospitalized with the diagnosis of schizophrenia according to DSM-IV criteria and who were between 15-65 years of age were included in the study. We evaluated the age, gender, marital status, number of children, onset of the disease and subtype of schizophrenia.Results: Mean of onset of the disease score was higher statistically in the females (27.6 ± 4.3) than the males (23.7 ± 3.9) (p < 0.05) in our study. The paranoid subtype was the commonest, while women were more likely to be married than men, men had more children than women; and the paranoid subtype were more likely to be married than the other groups.Conclusions: Onset age of schizophrenia was four years higher in the women than in men and that the rates of the schizophrenia subtypes were consistent with those detected in the other studies demonstrates that these rates were determined by neurobiological mechanisms rather than socio-cultural factors.

E ver since Bleuler published his account of nearly a lifetime's work with schizophrenia patients (1), there has been great interest in studying the long-term course of this illness. The evolution of schizophrenia's conceptualization from dementia praecox to a heterogeneous disorder with variable outcomes has been well documented. The multinational International Pilot Study of Schizophrenia (IPSS; 2) initiated by the World Health Organization (WHO) showed that it is eminently possible to use the same standardized criteria and instruments to compare the course and outcome of schizophrenia in different countries and cultures. Among the few studies with more than 15 years of follow-up have been those of Tsuang and Winokur (3), De Sisto and others (4), Huber and others (5), and Moller and others (6). However, the varying nature and size of the samples, the varying duration of follow-up, and the lack of uniform definitions 564

“…1 Moreover, women with schizophrenia usually present a second peak of onset between the fourth and fifth decade of life. [1][2][3] A later onset and a second peak in women with schizophrenia have been related to the estrogenic hypothesis of psychoses, which might explain many gender differences found in recent studies. 4,5 Gender investigations focusing on age at onset and clinical features have also been conducted in delusional disorder (DD).…”

Objective: To investigate gender differences in age at onset, psychopathology, and suicidal behavior rates in delusional disorder (DD). Methods: We conducted a prospective longitudinal study of 97 patients with DD. Demographic and clinical data at baseline were recorded. Gender differences were investigated by applying analysis of covariance, using age at onset and age at first psychiatric consultation as dependent variables, comorbid depression and gender as between-subject factors, and employment status, social support, and DD types as covariates. Results: Seventy-six percent of the patients were women. The average age at onset was 48.76612.67 years, mean age at first psychiatric consultation was 54.13613.67 years, and men were more likely to be employed than women (p = 0.041). Despite the earlier age at onset and at first psychiatric consultation in men, these differences tended to disappear when adjusted for potential confounders. There were no significant gender differences in depressive comorbidity, presence of suicidal ideation and behavior, or compliance rates at follow-up. Conclusions: Our findings could not confirm that male and female DD patients differ in age at onset, age at first psychiatric consultation, or suicidal ideation and behavior, even after controlling for potential confounders.
