Is there any difference between patients depression symptoms pattern who come to clinic in different seasons ?

Introduction: Depression is a serious and prevalent disorder that is 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. Method and Material: In a prospective descriptive study all of the patients that came to psychiatric clinic of Ernam-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 are 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. Results: 101 patients with mean age of 28.94 years old enter to the study; mean score of BDI were 27.64 with standard deviation of 12.43. There were 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 had not meaningful difference (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). Conclusion: In this study there were no difference between depression symptoms patterns of patients by sex and season.
