Objective: Suicide is one of the most important health problems in the world. Financial, academic, social, and environmental difficulties along with genetic, physical, and mental disorders affect suicide attempts. This study aimed to find risk factors for completed suicide in Ilam province according to the suicide registry in Ilam province. Method : This was a prospective study and was performed based on suicide case registration data, pre-determined checklist data, and death registration data in Ilam province from March 2019 to September 2020. Logistic regression models and the Chi-square test were used to determine the relationship between completed suicide and its risk factors. Results: Among 1,410 attempted suicides, 66 (4.7 %) were executed. Rate of completed suicides was higher in men (6.5%) compared to women (4.5%), (p = 0.005), age groups over 65 years (P < 0.001), retirees and farmers (P = 0.009), illiterate people (P < 0.001), villagers (P = 0.02), people motivated due to physical problems (P = 0.016), suicide by physical methods (P < 0.001) and self-immolation (P < 0.001). Logistic regression showed that incidence of completed suicide was significantly higher in the age group over 65 years, illiterate people, people using physical methods, villagers, and men. Multivariate logistic regression also showed that men and individuals using physical methods of suicide were significantly more successful in suicide. Conclusion: Men, the elderly, illiterates, villagers, and people who used physical suicide methods were in high-risk groups. Despite lower prevalence of suicide, a higher rate of completed suicide was demonstrated. To decrease completed suicide rates, we must pay attention to these groups.
