The main challenges leading to the decrease of bone mineral metabolism in the conditions of the North are covered. The presented results of a study of 29 soldiers serving in the extreme conditions of the North, to study the mineral density of bone tissue in the distal forearm. Revealed a significant decrease in bone mineral density, as well as a deficiency of essential elements in this cohort. So, when densitometric training of servicemen serving in the North, the average Z-test was 0±1,8 SD, the change in bone mass corresponded to the Z-test less than -2 SD, was determined at 31,03%. Vitamin D3 deficiency was detected in 96,5% of cases. Analysis of the bio-element state of the hair revealed a deviation of the reference interval in 100% of military personnel, a decrease in essential elements: cobalt, selenium, magnesium, vanadium and an increase in the level of barium, bromine, arsenic, as well as caesium. The interrelation of the elemental status and bone mineral density is revealed. 100% of the examined hair samples showed a significant decrease in the level of cobalt, selenium and iodine. (p0,05) a decrease in boron, magnesium, calcium, vanadium (p0,05) and a significant increase in chromium, manganese, and copper. A quantitative study of toxic elements revealed a significant (p0,05) increase in mercury, rubidium, strontium, and caesium. A correlation was established between the Z-test and the level of vitamin D3, body mass index and dynamometer. The data obtained determine the required level of trace elements in order to prevent disturbances of mineral metabolism and bone loss.
