Integrative estimation of vegetative status in children with different functional types of the constitution
Аim. To give an integrative estimation of the vegetative status in children 8-9 years old with different functional types of the constitution on a conceptual basis, to identify the risk groups of vegetative dystonia development. Materials and methods. 649 children (321 boys and 328 girls) of primary school 8-9 years old were examined in Tyumen. The pacing and the diary of physical activity were used to establish the individual volume of habitual motor activity (HMA). Functional type of constitution (FTC) was determined in accordance with the 3-component scheme by the level of habitual motor activity: low - LHMA-FTC-1, medium - MHMA-FTC-2 and high - HHMA-FTC-3. At rest, all children were assessed by heart rate and blood pressure, vegetative status (initial vegetative tone-IVT, vegetative reactivity-VR and vegetative maintenance of activity-VMA) with an estimation of the degree of tension of regulatory mechanisms was carried out by cardiointervalography using clinoortostatic tests. Results. Taking into account the conceptual approach (the concept of typological variability of physiological individuality), qualitative and quantitative characteristics of indices of vegetative regulation of cardiac activity in children with different levels of habitual motor activity (LHMA-FTC-1, MHMA-FTC-2, HHMA-FTC-3) were established. Vegetative profile of integrative estimation of vegetative status in terms of IVT, VR, VMA for children FTC-1 was characterized as the «lower border of sympathicotonia» - «hypersympathicotonia» - «sympathicotonia», for children FTC-2 «eutonia» - «normotonia» - «normal recovery period», for children FTC-3 «eitonium» - «the lower limit of hypersympathicotonia» - «sympathicotonia». The establishment of individual and typological features of the vegetative status in children of different FTC determines the possibility of predictive and current estimation of the body’s adaptive reserves, the identification of risk groups and the development of criteria for donor diagnostic diagnosis of vegetative dystonia.
