To clarify changes in mental disorder distribution in suicide attempters, a comparison was made between the period when an economic recession started (1992, 1993) and the period when the recession became serious (2000). The subjects were 212 suicide attempters admitted to the Emergency Medical Center of Tokai University Hospital during a 2-year period between 1992 and 1993 (group A) and 255 suicide attempters admitted during a 1-year period between January and December 2000 (group B). Mental disorders were classified according to the International Classification of Diseases (10th revision; ICD-10). Distribution was compared between groups A and B and significant differences were observed in mental disorder distribution (P < 0.001). The percentages of subjects with depression, those with neurotic disorders, and those with other disorders were higher in group B than in group A. Conversely, the percentage of subjects with schizophrenia was lower in group B than in group A. Mental disorder distribution in suicide attempters significantly changed. However, it was not certain that this change was related to the economic recession and increased unemployment in Japan.
