Abstract

Background: The study of suicide and identification of mental health problems, social, cultural, and environmental communities are effective for preventive measures and reducing risk factors. Objectives: This study aimed to study the epidemiology of suicide and its associated factors over 2011 - 2015 in Zarand. Methods: In this observational-epidemiological study (cohort study), all people who committed suicide in 2011 - 2015 were recorded on a standardized questionnaire, and demographic data of Zarand were collected by the health center and government. Data were analyzed by SPSS software using descriptive statistics, Chi-square tests, and logistic regression analysis. Results: During 2011 - 2015, 2,401 persons (372 at one hundred thousand) committed suicide, of whom 33 cases (5.1 at one hundred thousand) died. Chi-square and logistic regression information showed suicide attempt rate in people with middle school education was 15.7 times greater than less or more educated ones; similar results showed the rate of suicide of the people in the age group 15-29 was 6.3 times higher than other age groups, retired, and unemployed 3.1 times more than employed and finally, urban living had suicide attempt rate of 1.6 times higher than rural living. Conclusions: In Zarand, the incidence of suicide is much higher than the global, country, and province average (more than three to four times), and leading to death was much less than expected. However, there are significant differences in the cause and manner and demographic characteristics with other studies, which require the creation of Suicide Registry Center (SRC) and qualitative studies with form layer analysis of causes in Zarand.
