Background: In Japan, suicides are the cause of death for approximately 30,000 people every year.Suicide risks in the general population have been reported to be associated with not being married and being unemployed.However, in Japan, there is a poor understanding of the relative importance and effects of these factors in terms of suicides.Methods: All deaths identified as suicides according to the ICD-10 (codes X60-X84) were extracted from the vital statistics of Japan for the years 1995, 2000, and 2005.The population statistics for Japanese residents for these years were obtained from the census.Suicide rates were calculated for people aged 15 years and above by year, sex, marital status (married, never married, widowed, or divorced), and employment (employed or unemployed).To estimate the relative risks (RRs) of suicide and 95% CIs adjusted for age for each category, Poisson regression models were fitted to the data.Results: Crude mortality rates by marital status and employment showed that suicide rates among people who were divorced and unemployed were consistently and extremely high for both sexes, and especially among males they were 420.5 per 100,000 in 2000.In addition, Poisson regression models, which estimated relative risks of suicide for each category as compared to a reference group of employed married people, indicated that people who were divorced and unemployed had remarkably high relative risks in each year (e.g., RR =18.42 [95% Cl: 17.40-19.50] for men and RR =17.49 [95% Cl: 15.67-19.52] for women in 2005).Among women, those who were never married and were unemployed also had consistently high relative risks in each year (e.g., RR =12.54 [95% Cl: 11.31-13.91] in 2005).Conclusion: For both sexes in Japan, people who are divorced and unemployed are at a remarkably high risk for suicide.The findings suggest that the effects of divorce and unemployment on suicide deaths are multiplicative.
