Metabolic Indicators of Maladaptation of the Body of Water Transport Workers in the Republic of Sakha (Yakutia)

Changes in metabolism at high latitudes are a physiological adaptation to "northern stress" caused by the influence of meteorological and heliogeophysical factors. The study of metabolic blood parameters can serve to assess the risk of developing the disease in the future due to a decrease in the body's adaptive reserves when it is influenced by environmental factors of various nature. The stress potential of natural northern climatic and geophysical factors may increase in relation to those people who come to the North from regions with a temperate climate and work in specific conditions, in particular in water transport.The water transport workers of Yakutia in the number of 206 men were examined, with 96 of them coming from other regions of the Russian Federation. The biochemical parameters of blood serum were evaluated according to groups formed according to the level of adaptive potential (AP). Anthropometric (height, weight) and functional (heart rate (HR), systolic and diastolic blood pressure (SAD, DAD)) were determined body parameters, as well as biochemical parameters of blood serum. The level of AP, the de Ritis coefficient (CDR) and the atherogenicity coefficient (CA) were calculated. The results obtained made it possible to identify violations of adaptation processes among employees, mainly among newcomers. According to biochemical parameters, deviations in the level of enzymes, glucose, de Ritis coefficient (CDR) and atherogenicity coefficient (CA) were revealed.
