ABSTRACT

Depression is a serious and prevalent disorder known with persistent pathology of mood as the main symptom. Lifetime prevalence of depression is up to 25 percent. In different studies depression symptoms pattern of patients is reported different by sex, age, season and place and '. For this reason in this study we evaluate the differences of depression symptoms pattern by season. In a prospective descriptive study all of the patients that come to psychiatric clinic of Imam-Reza Hospital in winter of 1382 and summer of 1383 with chief Complaint of depression and were entered to the study all of the patients visited by a psychiatrist and for all of them we were filled both demographic information questionnaire and Beck Depression Inventory [BDI]. Data From different items of depression based on BDI were compared in two groups of winter and summer with 15 percent sensitivity. 101 patients with mean age of 28.94 years enter to the study; mean score of BDI was 27.64 with standard deviation of 12.43. There was no meaningful difference between severity of depression among two groups of winter and summer although items of preoccupation with body and somatic health meaningfully were in winter then in summer [P=0.03]. Total score of BDI in male and female patients were not different meaningfully [without relation to the season], but items of difficulty in beginning of the work [P=0.008] and diminished sexual desire [P=0.018] were meaningfully upper in men than in women. Mean of total score of depression in rural patients were meaningfully upper than urban patients too [P=0.025]. In this study there was no difference between depression symptoms patterns of patients by sex and season
