| Research Abstract |
Because suicide is increasingly becoming a public health threat in Japan, it is necessary to identify high-risk groups to develop effective preventive measures. The suicide mortality trends from 1985 to 2004 for Japanese aged between 15 and 79 years were analyzed by a Bayesian age-period-cohort analysis to evaluate the independent effects of age, period, and birth cohort. Moreover, we tried to analyze a Cluster analysis for the 47 regional suicide data. In conclusion, a gender difference was detected in the effects of age, period, and cohort on suicide risk among Japanese. Cluster analysis for the 47 regional suicide data revealed the different impact of age, period and cohort effects on suicide mortality between urban and rural regions.
