Epidemiology of childhood anxiety disorders

SummaryThis review studies the epidemiology of anxiety disorders of childhood and adolescence, including prevalence rates, comorbidity patterns, risk factors and course. Comorbidity is very important: most children with anxiety disorders also have one or several other anomalies, usually anxiety or mood disorders. The authors point out the main evidence suggesting that a number of risk factors are associated with childhood anxiety disorders: age, sex, low socioeconomic setting; child's personality, and lastly, familial risk factors which have a very strong influence: children of parents with current or past anxiety disorders are more at risk of having anxiety disorders. Concerning the course of disorders, we have tentatively defined subsets of children or adolescents with anxiety disorders, and tried to clarify the recovery rate of these subsets. Future directions for research are suggested.
