abstract: BACKGROUND
  Frequency of mood disorders in patients with chronic diseases, especially diabetes and its effects on life quality are dramatically increasing.
  
  
  OBJECTIVE
  This study aimed to investigate the relation between depression and quality of life in patients with diabetes.
  
  
  METHODS
  This is a cross sectional survey. Subjects were selected from 330 eligible people referred to the only diabetes clinic in Gorgan City during 6 months, using systematic random sampling. Beak Depression questionnaire and the brief questioner with 26 questions recommended by the World Health Organization (WHOQOL-BREF) were used to measure depression and quality of life, respectively. Data were analyzed through descriptive methods, Chi-square, Independent t test and linear regression model using SPSS16; moreover, P value < 0.05 was considered as significant.
  
  
  RESULTS
  In total, 330 patients with diabetes (35.5 % male and 64.5% women) were studied. The mean and standard deviation of their age and years involved with diabetes were 50.6 ± 9.0 and 5.4 ± 4.5 years, respectively. Range of age was 25 - 75 years, as well. The prevalence of depression in all patients with diabetes was 58.2% (124 mild, 56 medium, and 12 with severe depression). Hypertension was 13.9% more in diabetic patients with depression (P value < 0.001) and physical activity in 24.7% of the cases was less with a meaningful difference (P value = 0.01). The mean and standard deviation of quality of life in diabetic patients with and without depression was 50.7 ± 14 and 60.5 ± 13.3, respectively that was significant in two groups (P < 0.0001).
  
  
  CONCLUSIONS
  The prevalence of depression is high in patients with diabetes and has a considerable impact on the consequences of diabetes and quality of life too.
