Violence-related behaviors and self-inflicted injuries among 15-18 year old Iranian adolescents.

In this population-based cross-sectional study, we determined the prevalence of intentional injuries and associated factors among 1201 adolescents in Tehran, Iran. Overall, 63.9% of adolescents had at least one intentional injury behavior which was significantly higher in males. Gender preference for males by parents, very high or very low supervision, waterpipe smoking, and alcohol consumption were significantly associated with injuries in females. In addition, poor wealth index, parental punishment and smoking were incriminating factors in males.
