Abstract
Special attention is always paid to the health of children associated with the influence of environmental factors in scientific research. This is due to the fact that environmental factors play an important role in determining the health and well-being of children. Of particular importance is the search for informative integral indicators that characterize the impact of various degrees of anthropogenic load on the health of the child population. The article presents the results of a study of integral indicators of the health status of 315 children aged 4–6 years living in the territory with a high (group 1) and low (group 2) level of anthropogenic load, such as the stability of the nervous reaction, the stress index of regulatory systems, the index of vegetative equilibrium, the vegetative rhythm indicator, the indicator of the adequacy of regulatory processes. The obtained data indicate that a high level of anthropogenic load has an adverse effect on the integral indicators of the functional state of the central nervous, autonomic and cardiovascular systems. This is characterized by a decrease in the stability index of the nervous reaction, an increase in the sympathetic activity of the central nervous system, depletion of the central regulatory circuits due to prolonged activation of non-economic mechanisms for regulating the high tone of the sympathetic nervous system. At the same time, the adverse effects increase with an increase in the age of children from 4 to 6 years old living in an area with a high level of anthropogenic load. The established facts of changes in integral indicators represent a scientific justification for the use of these indicators in the development of mathematical models for managing risks to children’s health under the influence of anthropogenic factors.
