ABSTRACT. Recently, a balanced diet has been a popular object for study, both in Russia and abroad. The problem of preserving human health in the Northern regions, particularly in the area largely impacted by industry and environmental pollution, is highly relevant. Such conditions lead to a large number of chronic diseases among children and adolescents.It is known that substantial variations in power cause great harm to human health. Changes in the traditional food, a significant increase in consumption of carbohydrates (bread, sugar, canned goods) due to increased emotional stress, lead to the formation of pathology of the cardiovascular, respiratory, endocrine and other systems in the residents of the North. Formation of the strategies of local population nutrition is complicated due to a relatively poor species composition of local flora and fauna, unsuitability or small suitability of soils for agriculture, peculiarities of trace element composition of soils and food. Local residents are characterized by chronic deficiency of various micronutrients. Among the main causes of the formation of trace element deficiency states in human residents of the North, a major factor is low alimentary consumption of the trace elements themselves. The lack of micronutrients in the diet is combined with their high expenditure due to environmental and climatic stress in the northern region. It was found that even in healthy people in the North, there are signs of a polyhypoelementosis, which can cause serious metabolic disorders and impair functions of various organs and systems. The study is aimed at analyzing element status of children from the indigenous and non-indigenous population groups living in the northern regions of Russia. 300 school-age children from indigenous (Khanty) and the non-indigenous population of Yugra were observed. It was found that elemental profiles of children from the indigenous and non-indigenous population belong to different general assemblies; peculiarities of macro and trace elements level in children, depending on age and ethnicity, were revealed. Iodine and selenium were found to be most significant elements participating in the formation of child and youth population in Yugra.
