Around one in seven children and adolescents aged 10 to 19 are affected by mental health conditions – with anxiety, depression and behavioural disorders among the most common, according to a new World Health Organization and UN Children’s Fund report released on Wednesday. 

In addition, one-third of mental health conditions emerge before the age of 14 and half before the age of 18.

Published ahead of World Mental Health Day, celebrated annually on 10 October, the report seeks to support the transformation of mental health services for children and adolescents.
