Abstract

Introduction. In the conditions of the Far North (FN), it is relevant to identify disadaptation among workers.

Goal was to assess the significance of blood parameters in the diagnosis of disadaptive changes in the body in those working under FN conditions

Materials and methods. In the summer, total cholesterol, low- and high-density lipoproteins, triglycerides, vitamins (B9, B12, D), minerals (K, Na, Ca total and ionized, P, Mg, Fe), C-reactive protein, the mineral composition of drinking water was studied.

Results. Signs of anemia confirm a reduced level of cobalamin (100.7±5.2 and 101.4±3.7 pmol/L, p=0.921), B9 deficiency (86.3% and 93.3% (p=0, 696), low iron levels in 27.3% and 53.3%. Symptoms of hypotonic overhydration are determined by the consumption of low-mineralized drinking water from melted snow. The duration of work led to the development of triglyceridemia (in 50.0% and 60.0%), hypercholesterolemia (for total cholesterol in 90.0% and 93.3%, for low-density lipoproteins – in 90.9% and 73.3%). Elevated high-density lipoproteins among the first group in 72.7%, the second – in 36.7%, causing blood atherogenicity in 40.9% and in 80.0%, C-reactive protein (high in 13.6% and 66.7%) indicated to an increase in the risk of cardiovascular diseases. There were steepened vitamin D deficiency (insufficiency in 71.4% and 53.3%, deficiency in 28.6% and 46.7%), mineral imbalance (K in 9.1% and 20.0%, Ca ionized in 18.2% and 26.7%, Fe – in 9.1% and 20.0%).

Limitations. Blood indices in male military personnel with different lengths of stay in the Arctic, were studied in the summer.

Conclusion. It is necessary to determine high and low density lipoproteins, C-reactive protein, vitamins B12, B9 and D, minerals (potassium, sodium, ionized calcium and total calcium, magnesium, phosphorus, iron) regardless of age and work experience in the field.
