ABSTRACT

Self-injury [SI], also called self-mutilation or cutting, is highly stigmatized emotional disorder. The aim of this study was to estimate the incidence rate of self-injury among male pupils in Tabriz - North West in Iran and to evaluate the associated risk factors. In this longitudinal study of all the pupils high school in Tabriz, 1772 [13.7%] were randomly sampled, and assessed in this and subsequent year. A self-administered questionnaire with 48 questions was distributed to high school in February and March 2005. After one year [February and March 2006], another questionnaire with 10-items was distributed to those students to determine the incidence rate of self-injury. The influence of different factors on self-injury was evaluated with a logistic regression model. The mean age of the subjects was 16.3 +/- 0.87 [min 15, max 19] years. At the end of follow-up, 4.8% of pupils reported incidence of self-injury. Most type of incidenced self-injury were cutting and burning. The results of logistic regression model indicate that transition in smoking stages [OR=2.81], incidence of alcohol drinking [OR=2.27] and having smoker friend [OR=1.78] were factors associated with incidence of self-injury. This study showed that incidence rate of self-injury in this group of adolescents was 4.8% in one year, which related to age, alcohol and ciggaret smoking
