One in 10 children and young people of this age (or 293 million worldwide) lives with at least one diagnosable mental disorder. In these matters, age matters.

Anxiety predominates in the 5 to 9 year old group, while depressive disorders are more prevalent in the 15 to 19 year old and 20 to 24 year old groups. Sex is also determining. Men are more likely to suffer from alcoholism or drug abuse problems, while anxiety, depression or eating disorders is more prevalent among women.
