Assessment of hemograms in military servicemen at different durations of professional activity in the Arctic

Abstract

Extreme environmental factors can have a negative impact on human hemograms. The goal is to assess hemogram indicators in military personnel with different durations of professional activity in the Arctic during the summer period. We observed two groups with a duration of stay in the Arctic of up to 5 (No.1, n=20) and up to 10 years (No. 2, n=31). We carried out determinations of vitamins B12 and B9, minerals (K, Na, total Ca, ionized Ca, Mg, P, Fe) in blood plasma, and sanitary-chemical studies of water. The diet was assessed based on literature data. Questioned about tobacco smoking. We assessed working conditions according to the degree of harmfulness and danger. Hemoglobin in group No. 2–154.6±0.7, No. 1–156.9±0.9 g/l (p=0.041), the average hemoglobin concentration in the erythrocyte was 334.0±0.6 and 336.2± 0.8 g/l (p=0.008), average hemoglobin content in erythrocytes 29.1±0.2 and 28.0±0.2 (p=0.001), average platelet volume 9.33±0.4 and 9.14±0.05 fl (p=).008. In groups No. 1 and No. 2, respectively, decreased red blood cells in 30.0 % and 6.7 %, decreased hematocrit in 20.0 % and 0 %, increased average volume of red blood cells in 10.0 % and 6.7 %, the hemoglobin content in the erythrocyte is reduced in 20.0 %: and increased in 20.1 %, the average hemoglobin concentration is normal and reduced in 20.1 %, the average platelet volume is normal and increased in 20.1 %, band neutrophils are reduced in 100.0 % and in 80.0 %, segmented — normal and reduced in 13.4 %. Water supply was provided with low-mineralized water, food was provided with canned food; work is harmful in terms of intensity (3.2) and severity (3.2). Quantitative and qualitative changes in blood parameters with different durations of professional activity characterize the versatility of the influence of health risk factors. The data obtained lead to a study of the content of vitamin B12, folic acid, as well as the mineral balance of the body to develop specific preventive interventions to preserve the health of military personnel.
