Background: The importance of risk factors in the prevention of suicide has been recognized. The aim of this study was to identify important risk factors associated with the repetition of suicide attempts in adolescents and adults using one-inflated positive count modelMethods: The subjects of this research consisted of 701 patients (183 adolescents and 518 adults) with at least one unsuccessful suicide attempt in Isfahan, Iran. Data were collected using the ‌Diagnostic and Statistical ‎Manual of Mental Disorders, 4th edition (DSMIV). The collected data were analyzed through descriptive statistics and positive one-inflated regression models.Findings: The one-inflated positive Poisson was the best fitted model for adolescents in this study. The factors of age and family history of suicide had a positive effect, and adjustment disorder, compared to depression disorder, had negative effect on repetition of suicide attempts among adolescents. The results of one-inflated positive negative-binomial model for adults suggests that rural inhabitancy, family history of suicide attempts, and impulsive suicide attempts had positive effects on repetition of suicide attempts. In addition, a higher rate of repetition of suicide attempts was observed in individuals with bipolar disorder than subjects with depression.Conclusion: The factors of adjustment disorder and age had significant effects in adolescents, and rural inhabitancy and bipolar disorder were effective factors in adults. Moreover, family history of suicide was associated with repeated suicide attempts in both adolescents and adults.
