Key result
Residence in an industrial city was associated with a higher prevalence of autonomic dysfunction syndrome in school children compared to rural areas (69.2 vs 7.7 per 100 children).
Why the study?
Prevention of the syndrome of autonomic dysfunction remains relevant due to its high prevalence and risk of transformation into chronic cardiovascular diseases.
Do environmental factors and lifestyle influence the formation of the syndrome of autonomic dysfunction in school children?
Cross-Sectional (n=786)
Yes
Do environmental factors and lifestyle influence the formation of the syndrome of autonomic dysfunction in school children?
Absolute Event Rate: 69.2% vs 7.7%
Environmental factors, particularly air pollution and formaldehyde exposure, are significant risk factors for the development of autonomic dysfunction syndrome in school children.
Environmental and lifestyle factors may inform SAD risk in iodine-deficient regions; leaves open causal validation in prospective studies.
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.

Nv et al. (2019) conducted a cross-sectional in Syndrome of autonomic dysfunction (SAD) (n=786). Environmental and lifestyle factors (industrial city residence, air pollution, training load) vs. Rural residence / lower exposure was evaluated on Prevalence of syndrome of autonomic dysfunction (SAD). Residence in an industrial city was associated with a higher prevalence of autonomic dysfunction syndrome in school children compared to rural areas (69.2 vs 7.7 per 100 children).
