Prevalence of Mood Disorders in Iran


Objective: To study the prevalence and demographic characteristics of mood disorders among Iranian adults.
In this cross-sectional population-based epidemiological study (age > 18) in Iran, 25180 individuals were selected through a randomized cluster sampling method for a diagnosis using the Schedule for Affective Disorders and Schizophrenia (SADS). They were then interviewed at home by 250 trained clinical psychologists.
The estimated lifetime prevalence of Major Depressive Disorder (MDD) and Minor Depressive Disorder (mDD) were 3.1% and 0.3% respectively. Also, the estimated lifetime prevalence of Bipolar Mood disorder (BMD) type I and type II were 0.1% and 0.7% respectively. The current prevalence of MDD, mDD, BMD-I, and BMD-II were 1.8%, 0.2%, 0.04%, and 0.3% respectively. Mood disorders were associated with female gender, lower education, being married, being middle-aged, living in cities, and not being a homemaker.
Conclusion: The prevalence of mood disorders was lower among Iranian adults than reported in Western studies, and a number of demographic associations differed from those reported in Western studies. Important cultural differences in the nature or manifestation of depression are implied by these results.
