title: Gender and ethnicity in first admissions to a psychiatric unit in Trinidad.
abstract: It has been recognized that there are gender disparities in the admission rates to psychiatric units. While the community prevalence of the major non-organic psychotic mental disorders are thought to have no gender bias, non-psychotic disorders such as depression are more commonly diagnosed in women. Gender differences in admission may indicate differences in severity or in presentation to psychiatric services and would have important implications for the targeting of preventative strategies. The case notes of all admissions to the psychiatric unit at the San Fernando General Hospital were obtained for the calendar year 1999. The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) diagnoses and gender were analysed to determine the distribution of diagnostic categories by gender. A total of 119 patients were admitted to the unit for the first time in the period under review, 72 were male (60.5%) and 47 were female (39.5%). There were no significant differences in age by gender. Substance use related admissions and psychotic illnesses (schizophrenia spectrum and affective psychoses) were significantly more common in men (p = 0.006; p = 0.03 respectively). These differences were especially marked for those of East Indian descent. Non-psychotic illnesses were more commonly diagnosed among women (p = 0.0008). These findings suggest that a larger proportion of males are admitted to the general hospital psychiatric unit among first time admissions. This is also true for re-admissions. Men are more likely to be diagnosed with substance use and psychotic disorders, while for women, major depression and non-psychotic illnesses are the main diagnoses. Community surveys are needed to determine whether this demographic pattern of admission reflects the population prevalence of these disorders. Reduction of admission rates will require interventions that are sensitive to gender differences in diagnosis among those admitted to psychiatric units.
