Those are shocking figures and something we should feel ashamed of.
The Ministry of Health deputy director of mental health Dr Ian Soosay commented: "It's not just here but in countries as diverse as the UK, China and India. Mental health is now becoming a leading cause of disability.
"And from a scientific point of view, we don't really know what's caused it."
So what has happened to us - and particularly to our young people?
My teenage years were a long time ago, but I never heard of any of my peers suffering from depression or taking medication.
Bullying, domestic violence and child abuse are cited as reasons behind the growing desperation that seems to be enveloping our young people, so it is just a case that life was a lot simpler back then.
I spent my time kicking a football around and while I got anxious about exams and girls (not necessarily in that order), I wouldn't have dreamed of going to a doctor.
I feel for young teens today (and I have three of them), life seems more complicated, more pressured and, of course, social media does much to exacerbate those problems.
Is it too naive to say: "It's the internet what's done it"?
Whatever is driving this, we need a serious and determined effort to turn the tide.
