Epidemiology of Suicide by Burns in the Province of Isfahan, Iran

Abstract

The aim of the study was to determine epidemiologic features and factors associated with suicidal behaviors by burns requiring hospitalization in the province of Isfahan, Iran. A prospective population-based study of all suicidal behaviors by burns requiring hospitalization was conducted in the province of Isfahan, Iran, from March 21, 2005 to March 20, 2006. Data were obtained from patients, family members, and/or friends through interviews during the course of hospitalization. A total of 89 patients ages 13 to 62 years with suicidal behaviors by burns were identified during the study period, representing an overall incidence rate of 2.9 per 100,000 persons-year (P-Y; 95% confidence interval 2.3-3.5 per 100,000 P-Y). Females (4.7 per 100,000 P-Y) had a higher rate of suicidal behavior by burns than males (1.2 per 100,000 P-Y; P < .001). The age-specific rate of suicidal behavior by burns peaked at age group 20 to 29 years (6.3 per 100,000 P-Y). Among the population aged 15 to 29 years, married women had a higher rate of suicidal behavior by burns (9.3 per 100,000 P-Y) than single women (6.6 per 100,000 P-Y). The highest rate of suicidal behavior by burns was found among the unemployed population (17.7 per 100,000 P-Y). The most frequent precipitating factor for suicidal behavior was a quarrel with a family member, relative, and/or friend (61.8%). Depression and anxiety disorders were the most frequent psychiatric comorbidities associated with suicidal behaviors. Mortality rate caused by suicidal behavior by burns was 1.4 per 100,000 P-Y. A high rate of suicidal behavior among young and mostly married women in the province of Isfahan is a tragedy and great concern. Social, cultural, and economical factors may contribute to suicidal behavior in Isfahan, and they need to be addressed through education, support, and commitment. Findings of this study can be used for implementation of a preventive program(s) to reduce the incidence of suicide among high risk groups.
