title: Substance abuse in high school students in association with socio-demographic variables in northwest of iran.
abstract: BACKGROUND
  Substance abuse in adolescents and its often tragic consequences, including addiction, is one of the preventable major public health problems. The aims of this paper were to estimate the prevalence of substance abuse and to evaluate its some associated factors in adolescents of Tabriz City (northwest of Iran).
  
  
  METHODS
  A self-administered questionnaire was completed in 4903 randomly selected students with mean age of 15.7 years old. The aim of the questionnaire was obtaining information on substance abuse, socio-economical information, cigarette smoking behavior, general risk taking behavior, self-esteem, attitude towards smoking and self-injury as well as demographical characteristics.
  
  
  RESULTS
  Prevalence of substance abuse was 1.4% (95% CI: 1.1-1.7) which was different statistically significant between boys (2.4%) and girls (0.6%) (P<0.001). Older age (OR=1.43), not living with parents (OR=2.34), having general risk taking behavior (OR=2.26), higher smoking stage (OR=2.39), lower self-esteem (OR=1.09) and positive attitude toward smoking (OR=1.08) were factors associated with student's ever use of substance.
  
  
  CONCLUSIONS
  The result has shown low prevalence of substance abuse in Iranian adolescents. Our findings showed some associated factors such as lower self-esteem with adolescent's substance abuse.
