Epidemiology of Suicide/Suicide Attempt and Its Association with Individual, Family, and Social Factors in Eastern Part of Iran: A Historical Cohort Study

Background: Suicide/suicide attempt, as a major public health problem, has been included among anti-social behaviors. We aimed to investigate the epidemiology of suicide and some associated individual, family, and so-cial factors. Methods: A historical cohort study was conducted among all cases (748 persons) reports related to suicide/suicide attempt that register in hospital reporting system and health care center in Gonabad and Bajestan, Iran, from 2009 to 2014. The required data were extracted through a checklist. Descriptive (mean and standard deviation) and analytic statistics (t-test, Chi-square, and logistic regression) applied to analyzed data. All data were analyzed using SPSS software. Results: Of the 748 reported suicide attempters, 17 cases (2.3%) had completed suicide. The annual average incidence rate of suicide was 110.03 per 100,000 populations. The mean age of suicide attempt had significantly decreased during the time (P=0.007). Furthermore, a significant association was observed between outcome of suicide and place of residence (P=0.019), history of physical illnesses (P=0.002), and method of suicide (P=0.001). Conclusion: Due to trend of age among suicide attempters, considering intervention programs of suicide prevention for school pupils and university students especially individuals residing in rural areas, as well as individ-uals suffering from physical illness would be effective to reduce the rate of suicide.
