Abstract

BACKGROUND: There have been no longitudinal studies in Japan examining national-level data for suicide risk by marital and employment status. We examined the age-adjusted relative suicide risk (RR) by marital and employment status from national data acquired for all suicides in Japan occurring in the past 25 years. METHODS: All deaths identified as suicides according to ICD-9 and ICD-10 were extracted from vital statistics data of Japan for the years 1980, 1985, 1990, 1995, 2000 and 2005. Population statistics for Japanese residents aged ≥15 years were obtained from the census. RESULTS: Suicide rates for almost all categories analyzed decreased in both genders between 1985 and 1990 and increased between 1995 and 2000, especially among men. Unemployed and divorced men had a consistently higher RR in each year analyzed. Unemployed and divorced women had a higher risk than those in other categories, especially in 2000 and 2005. In women, particularly in 1980, 1985 and 1990, those who were unemployed and never married had a similar RR to those who were unemployed and divorced. CONCLUSIONS: Unemployed and divorced people were at a high risk of suicide over the past 25 years, particularly in 2000 and 2005. Our findings suggest that the effects of divorce and unemployment on suicide risk are synergistic.
