It is known that external and internal factors influence the formation of human mineral metabolism depending on its habitat, climate, nutrition, nature and type of activity, features and national traditions. Aim. Assessment of the content of potassium, sodium, calcium, magnesium, phosphorus in the hair of students to identify the features of mineral exchange of foreign students depending on the region of permanent residence; according to the results of the survey to recommend a set of measures aimed at reducing the incidence, increasing adaptive capacity, improving the quality of life and education in the first year of study at the University. Material and Methods. Male (177 people) students of the first year of study (average age from 18 to 38 years), who came to study from different countries of the world, were selected hair samples for analysis of the content of macroele-ments (K, Na, Ca, Mg, P) by inductively coupled plasma mass spectrometry (ISP-MS) on the Nexion 300D device ("Perkin-Elmer", USA) after microvawe decomposition. Results. The content of these macroelements in hair was compared between groups of foreign male students from different countries, as well as for-eign students with Russian students. The elemental composition of hair in different countries is different, especially the difference in the content of cal-cium in the hair of students of the 5th and 6th groups compared to the 4th. In terms of potassium content, a significant difference was found in the 3rd group compared to the 1st and 2nd. According to the concentration of magnesium in the hair, significant differences were observed between groups 1 and 3, 1 and 4, 2 and 5, 3 and 4, 5 and 4, 6 and 4. In terms of sodium content, significant differences were found between the 1st and 3rd groups. The phosphorus concentration was significantly different in groups of 5 and 3. Conclusions. Determination of the content of potassium, sodium, calcium, magnesium and phosphorus in the hair of foreign students of the first year of study with subsequent corrective measures can be recommended in or-der to improve adaptation, increase the effectiveness of training and reduce morbidity.
