AbstractObjective To assess the independent risk factors of attempted suicide and the
importance of mental illness as a risk factor. Methods Detailed assessments of 152 suicide attempters
treated in general hospitals and 152 matched controls through questionaires. Results The rate of mental
illness in the suicide attemptersgroup was significantly higher than that in the control group (37. 7 %
versus 4. 0 % , paired Chi square = 45. 45 , P < 0. 001) . Conditional logistic regression identified three
independent predictors of suicidal behavior : severe acute stress ( OR = 67. 47 , 95 % CI : 8. 852514. 56) ,
presence of mental illness ( OR = 13. 85 , 95 % CI : 2. 01295. 55) , and immense psychological effect of
negative life events in the prior year ( OR = 5. 30 , 95 % CI :1. 12226. 08) . Conclusion Mental illness is an
important risk factor of attempted suicide , but not an essential pre2condition of suicide attempts. It is
important to establish a national suicide prevention plan that which is pertinent to the conditions in China.
