The suicide rate in Taiwan has remained highly in the last decade. Gradually, the suicide related problems have been taken seriously. Researchers from many different fields have been devoting themselves to explore this topic, e.g. epidemiology, psychiatry, psychology, sociology, economics...etc. The aim of this study is to explore the possible risk factors for suicide and its recurrence. Accumulating four data sets from four medical centers in Taiwan, we applied logistic regression to explore the possible relationships between the odds of recurrent event of suicide and some potential prognostic factors. The comparisons of cumulative occurrence rates of suicide were done by the Kaplan-Meier method. Cox''s Proportion Hazards Models were used to compare the duration from date of birth to the time of first suicide or time to hospitalization due to suicide after adjusting the effects of some potential confounding variables. We found that the risk of recurrent rate was higher for younger person. Other significant risk factors were gender (Female was higher than male) and marriage status (single was higher than married). After adjusting the effect of age, the hazard rates of first time suicide and/or first time hospitalization due to suicide were statistically significant among different education levels and/or marital statuses. Especially, person with education level lower than or equal to junior high has lower occurrence rate compare to other education level person.
