Épidémiologie des troubles psychiatriques en pédopsychiatrie

This article reviews findings from epidemiological surveys of psychiatric disorders in children and adolescents. Prevalence estimates, and gender and age correlates are provided and, when available, incidence data. We start with findings from major surveys that yielded estimates of global morbidity due to psychiatric disorders in youth. Hen, a detailed review of epidemiological findings is provided on a disorder by disorder basis, including: autism and pervasive developmental disorders, attention deficit hyperactivity disorder (ADHD), anxiety disorders, obsessive compulsive disorders, affective disorders including major depression and dysthymic disorder, anorexia and bulimia nervosa, schizophrenia and bipolar disorder. We conclude with estimates of numbers of children affected with a psychiatric disorder in France. A conservative figure is that 1 out of 8 children is suffering from a psychiatric condition at any time.
