title: [ABO blood group system and vegetative-vascular disorders in children].
abstract: The distribution of the blood groups of the ABO system was examined in 159 children with various vegetovascular disorders. The results were compared with the data on the distribution of the same blood groups in local population. A statistically significant (P less than 0.001) prevalence of persons with blood group A(II) and a lesser number of persons with blood group O(I) was revealed among the patients. It is assumed that the blood group A(II) is an unfavourable factor for children with vegetovascular disorders. An analogy is drawn with various diseases and cerebral circulation impairments in adults in whom a number of authors consider the blood group A(II) to be a risk factor.
