The importance of the frequency of suicide attempts as a risk factor of suicide.
The number of suicides in Japan has increased from approximately 22,000 per year in 1988-1997 to over 30,000 per year since then. The number has also increased in Mie Prefecture during this period. According to many reports, suicide attempts are one of the risk factors of suicide. In the present study, we investigated the incidences and circumstances of all suicide cases between 1996 and 2002, focusing in detail on the frequency of suicide attempts and general differences in the frequency of all suicide cases. During the 7 years, 1979 male and 969 female suicides were reported to Mie Prefectural Police Headquarters. During the test period, there were suicide attempts in 13.4% of all suicidal cases, 10.7% for men and 18.9% for women. The average age was 48.98 years (SD 17.68), 47.07 years (SD 16.32) for men, and 51.19 years (SD 18.89) for women. Among men, we discovered the risk factors of suicide attempts in completed suicides, which were "single time" of suicide attempts, "living with family" for the family constitution, and "visiting treatment" of the admission statuses. Among women, the risk factors were "living with family" and "visiting treatment". We must pay attention to those risk factors.
