This review study fills an important gap by aiming to determine the age changes in attempted and completed suicide in Iran during the past decade. A systematic review of related articles in international and Iranian databases from January 2008 to January 2020 was first conducted and relevant studies were extracted based on established criteria. Results showed that the mean age of suicide in Iran is 29.8 (range 27.7 – 31.8) years old for men and 27.4 (range 25.8 – 28.9) for women (P < 0.0001). The youngest and oldest populations of completed suicide belong to eastern and central regions of the country respectively. Findings imply the critical importance of increasing awareness through educational programs and public health campaigns to increase awareness and reduce suicidal behavior in Iran.

本综述研究旨在确定过去十年伊朗未遂和已完成自杀的年龄变化，填补了一个重要空白。首先对 2008 年 1 月至 2020 年 1 月期间国际和伊朗数据库中的相关文章进行系统评价，并根据既定标准提取相关研究。结果显示，伊朗男性的平均自杀年龄为 29.8（范围 27.7 – 31.8）岁，女性为 27.4（范围 25.8 – 28.9）（P < 0.0001）。完成自杀的最年轻和最年长的人口分别属于该国东部和中部地区。调查结果表明，通过教育计划和公共卫生运动提高认识以提高认识并减少伊朗的自杀行为至关重要。
