title: Prevalence of Anxiety Disorders among Children and Adolescents in Iran: A Systematic Review.
abstract: OBJECTIVE
  We aimed to conduct a review to investigate the prevalence of anxiety disorders among Iranian children and adolescents.
  
  
  METHODS
  We systematically reviewed the literature up to June 2014. We searched three Persian databases (Magiran, IranMedex and SID) and three English databases: PubMed, Scopus and PsycINFO. All original studies that investigated the current prevalence of anxiety in a sample of Iranian children and adolescents were entered into the study. All studies conducted on special samples or in special settings were excluded. By searching English databases, we obtained 124 original studies. After removing duplicate papers, 120 articles remained. In the next step, we screened the articles based on their title. In sum, 95 Persian and English articles had relevant titles. After screening based on the abstract and full text, 26 studies remained. After screening based on the full text, all selected studies were qualitatively assessed by two evaluators separately.
  
  
  RESULTS
  Twenty five studies were eligible and reported different types of anxiety disorders (i.e., generalized anxiety, separation anxiety, obsessive-compulsive disorder, phobias and panic disorder). The samples varied from 81 to 2996 among studies and their age range was 5 to 18 years. These studies were conducted in different cities of Iran. SCL-90 is a frequently used questionnaire. All anxiety disorders were mostly investigated with the prevalence rates ranging from 6.8% in Saravan to 85% in Bandar Abbas. OCD was the second common study with prevalence rates ranging from 1% in Tabriz to 11.9% in Gorgan.
  
  
  CONCLUSIONS
  Our findings revealed considerable amount of anxiety disorder among Iranian children and adolescents. Given the fact that anxiety disorder has negative effects on the well-being and function of individuals and can lead to severe problems, this disorder should be considered in mental health programs designed for children and adolescents.
