Surge in depression among teens: Mental illness rates are rising four times faster in young people than anyone else in the US, study finds

Depression continues to surge among US teens, according to a new study.

A Columbia University study found that Americans have become increasingly depressed over the last ten years, but teens are more at risk of psychological distress than other age groups over 12 years old.

Depression among teens rose at quadruple the rate of the general population from 2005 to 2015, according to the new research.  

The study was based on an annual survey of more than 600,000 people over the age of 12 in the US.
