Results: The prevalence of depressive disorder among patients with T2DM assessed by clinical criteria of ICD 10 was 31.4% in which severe (7.6%), moderate (19.5%) and mild depression (4.3%). Health behavior associated with depression in patients with T2DM are light or moderate activities such as practising yoga, walking, riding bicycle ... that help reduce the rate of depression, while working hard or playing heavy sports increases the rate of depression.
