The aim of this study is to find the possible relationship between psychiatric disorders and epidemiological characteristics of the patients. this was a cross-sectional study in which 3935 patients were recruited from 2004 to 2010. the patients were diagnosed to at least one of the following disorders such as anxiety, cognitive, behavioural, substance abuse, bipolar I &II &NOS, psychotic, psycholotemic, and depression. The distribution of each psychiatric disorder and its related factors were analysed using logistic regression method. Ratio of male to female was 1.2. The mean±SD of the age of the patients was 33.1±0.2 that showed men were younger than women. Bipolar I, psychotic, and depression were respectively highest frequencies among the other psychotic disorders. The higher the age, the higher the chance of suffering from depression, cognitive disorder, and substance abuse and the lower the chance of suffering from bipolar I and psychotic. The odds were higher for smoker to suffer bipolar I, NOS, and drug use disorder than non-smoker. Also, patients with more hospital admission were more at risk of anxiety, bipolar I, II, and psychotic disorders. In previous studies the odds of suffering from psychotic and bipolar disorder was higher in patients with hospital readmission as was seen in this study. In this work women were seen to be more at risk of anxiety, bipolar and depressive disorders than men and also males were more prone to drug use and psychotic disorders compared to females. These results are similar to the previous studies.
