[Anxiety disorders in children: incidence, comorbidity and risk factors].

According to epidemiological studies, prevalence of children's anxiety disorders is about 10%. Among children who suffer from anxiety disorders, a majority also presents one or more anxiety or mood disorders. The children's sex and age are likely to influence anxiety disorders. As well as the children's personality: studies about 'temperament' indeed pointed up this notion. Low socio-economic level of family could be a risk-factor, the importance of which varies according to anxiety disorders subtypes. Current and/or history of parental anxiety disorders, presenting or not with mood disorders, increase the risk for their children to suffer from anxiety disorders.
