Scientists have found evidence of a link...

    Scientists have found evidence of a link between social and economic status and childhood attention deficit disorder(ADHD)(注意力缺陷多动障碍)in the UK. A team led by the University of Exeter Medical School analysed data from the Millennium Cohort Study, a database of more than 19, 500 UK children born between 2000 and 2002 .The study was published in the Journal of Child Psychology and Psychiatry.

Findings showed that more children with ADHD came from families below the poverty line than the UK population as a whole, with average family incomes for households whose study child was affected by ADHD at £324 per week, compared to £391 for those whose child was not. The study found the odds (机会)of parents in social housing having a child with ADHD was roughly three times greater than for those who owned their own homes.

The team also found that the odds of younger mothers having a child with ADHD were significantly higher than for other mothers. Mothers with no qualifications were more than twice as likely to have a child with ADHD than those with degrees, and lone (孤独的)parents were more likely to have a child with ADHD diagnosis than households with two live-in parents.

Information was gathered from surveys when the cohort children were nine months old, and at the ages of three, five, seven and eleven.

Dr Ginny, of the University of Exeter Medical School,who led the study, said, "There is a genetic element to ADHD,but this study provides strong evidence that ADHD is also associated with a disadvantaged social and economic background. Some people believe that ADHD in children causes disadvantage to the economic situation of their family, but we found no evidence to support that theory. It's important to discover more about the causes of this disorder so that we can look towards prevention, and so that we can target treatment and support effectively. "

B. children affected by ADHD consume family incomes of £324 per week
