Suicide is one of the ten leading causes of death in Western countries and the second leading cause in people aged 15-19 years. In recent decades, annual suicide attempts reportedly ranged from 2.6 to 1,100 per 100,000 people, while the rate of lifetime prevalence ranges from 750 to 5,930 per 100,000 worldwide.1 Studies regarding suicide in Iran showed that most attempts originated in urban areas, and a recent systematic review focusing on seasonal variation indicated that most suicides were committed in the spring and summer seasons.2
