One in ten children aged 5-16 has a clinically diagnosed mental disorder, the most common being conduct disorder, followed by anxiety or depression, a proportion which appears to have been stable at least since 1999. However, the average amount of alcohol drunk by children aged 11-15 has increased, doubling since 1990.
These findings are contained in two reports from National Statistics1. On mental health the main findings are that boys are more likely than girls to have a mental disorder. Among 5-10 year olds, 10 per cent of boys had a mental disorder, compared with 5 per cent of girls. In 11- 16 year olds, the proportions are 13 per cent for boys and 10 per cent for girls. The prevalence of mental disorders is greater among children:

Other factors associated with an increased prevalence of disorders are lower status jobs, living in the social or rented sector and living in areas classified as ‘hard pressed’ compared with more affluent areas.
Children with emotional disorders and with conduct disorders are significantly more likely than others to smoke, drink and take drugs, the largest differences being in relation to smoking and drug taking.
In relation to drinking by 11-15 year olds, the figures for 2004 are in line with the trends of previous years. The proportion of children who report drinking did not change – indeed, in 2004 there was a 2 per cent drop compared with the previous year – but the amount consumed by children who did drink increased. The average weekly consumption of alcohol increased from 5.3 units in 1990 to 10.7 in 2004. A quarter of children who had drunk in the last week had consumed 14 or more units, an average of two or more units per day.
