Demographic information and clinical characteristics were collected. The participants were divided into four age groups and the characteristics of each group were compared. ResultsA total of 834 participants were included in this study. Suicide attempts were more prevalent in females, and the gender difference decreased with age. Having religious belief and less educated suicide attempts were concentrated in the elderly groups. Adolescents suicide attempts were more likely to occur in the spring, autumn and during non-office hours. Mental disorders were the major motivation for suicide among adolescents, and interpersonal and social problems were more prevalent among youths. Psychiatric medication was the leading suicidal substances among adolescents, while pesticides and herbicides were more prevalent in adults. The history of psychiatric diagnosis was more common in adolescents, while the history of somatic disorder was more prevalent in the elderly.
