Hygienic assessment of the immunobiochemical status of children of Far North aboriginal nationalities

: The study covers the influence of tuition, dwelling and nutrition conditions in boarding school on metabolism and immunity of pupils during the initial and final stage of tuition. The actual dietary intake in boarding school was found to have a carbohydrate bias and be short of micronutrients. The study established age-specific and regional peculiarities of immunological and biochemical parameters of schoolchildren's health status in Far North. The authors conclude that the alteration of metabolism typical of arctic aborigines is not genetically determined, but is observed as a result of ontogenesis. The study revealed alimentary-dependent changes in biochemical parameters of lipid, mineral and vitamin exchange. The results show that arctic children experience adaptive exertion and immunity alteration due to the change of living stereotype and the character of nutrition.
