Mental health disorders in children living in the U.S. have been rising over the past ten years.
A CDC study published in the 'Morbidity and Mortality Weekly Report' found that 13 to 20 percent of children have experienced a mental disorder.
Researchers base these figures on surveillance data from various federal agencies, including the CDC, between 1994 and 2011.
In 2010, the second leading cause of death among children aged 12 o 17 was suicide.
Data from that same year shows that mood disorders were the main diagnosis for children hospitalized in the U.S.
Of all mental disorders, ADHD was the most prevalent at 6.8 percent. Behavioral or conduct problems were next with 3.5 percent, followed by anxiety at three percent and depression at 2.1 percent.
The CDC concluded more comprehensive surveillance of these disorders is needed for the health and well-being of children.
