ON THE QUESTION OF THE IMPACT OF ENVIRONMENTAL FACTORS AND LIFESTYLE ON THE FORMATION OF THE SYNDROME OF AUTONOMIC DYSFUNCTION IN SCHOOL CHILDREN

Abstract

Introduction. Prevention of the syndrome of autonomic dysfunction (SAD) remains relevant due to the high prevalence and risk of transformation into chronic diseases of the cardiovascular system. Aim to assess the information content of the environmental factors and lifestyle in the formation of SAD in school children. Material and methods. The studies were carried out in urban and rural iodine-deficient territories of the Irkutsk region with different levels of the technogenic load. A total of 786 school children were examined, 250 children aged 7-17 years were included in the group for the analysis of informative factors. Factors of a way of life, quality of an inhabitancy, biological factors are studied. The influence of the factors studied on the formation of SAD was determined using the Bayes method. Results. SAD was found in the surveyed group at a frequency of 28.2 ± 2.8 per 100 children. The highest prevalence of this pathology was noted in children in the industrial city - 69.2 ± 3.7, in rural areas - 7.7 ± 2.8. Priority risk factors that can contribute to the development of a SAD in children are identified: an index of the air pollution = total exposure of formaldehyde > volume of training load > intensity of training work > child gender > excretion of formaldehyde > excretion of iodine in the urine> personal anxiety. Conclusions. The factors of the information content of risk factors in the formation of SAD in schoolchildren can be used for the early detection of persons at risk in conducting preventive medical examinations.
