Lifetime prevalence of MDD was 11% among that sample, and 12-month prevalence was 7.5%, said Shelli Avenevoli, Ph.D., of the Division of Translational Research at the National Institute of Mental Health and colleagues in the January Journal of the American Academy of Child and Adolescent Psychiatry.
Age and gender influenced prevalence, they said. Severe MDD was more common among older adolescents, and girls had two to three times the risk of MDD and four times the risk of severe depression than boys. Almost 30% of those with MDD reported suicidality, and 10.8% said they had made a suicide attempt. Significant levels of impairment and comorbid psychiatric disorders were present as well.
"[However,] the majority of depressed adolescents did not receive treatment specifically for their depression or from the mental health sector for any emotional or behavioral problem," Avenevoli and colleagues found. "These findings underscore the ubiquitous nature of this disorder in youth, suggest that a significant portion of depressive disorders have their first onset in adolescence, and support the notion of routine and universal screening during adolescence.”
