Hyperactive children start smoking oftener - scientists
Children with hyperactivity syndrome begin to be interested in cigarettes and smoke earlier and twice oftener than their peers without such diagnosis, consider Britain researchers from Cardiff University.
Scientists have examined 454 children with diagnosis "attention deficit/hyperactivity disorder" that was confirmed in the age from 6 to 12 years.
Researchers have also interrogated 394 mothers of children being under test and have found out that 171 women were smoking during pregnancy. Parallel were made genetic analysis of children's blood samples and also of their parents, brothers and sisters.
Specialists have found gene one of variations of which was associated with quantity of smoked cigarettes and more difficult forms of attention deficit/hyperactivity disorder. It appeared that this gene version is polymorphism RS 1329650 - is able to be transmitted from parents and is often met among children with higher points according to behavioral tests on attention deficit/hyperactivity disorder and cognitive dysfunctions.
At the same time researchers haven't managed to determine dependence among mothers' smoking and presence of this gene.
Experts have informed that finding genetic risk factors among people can help in mental disturbance prediction and other variants of declinations.
