The introduction of a system for monitoring the body’s functional state and nutritional characteristics into the medical university educational process seems to be a relevant solution to the problem of maintaining the health of student youth. The study aimed to test the use of the Valeoscan program for monitoring the health and diet features in the 1^st-year, 4^th-year, and 6^th-year students of the Medical Institute of the Tula State University (n = 3676). A significant (p < 0.05) increase in the time it took to complete psychophysiological tests was reported in the first-years, who studied in 2016−2023: the time to complete the correction test increased from 200.59 ± 4.21 s to 231.83 ± 5.71 s in females; from 202.40 ± 6.02 s to 229.00 ± 7.34 s in males. In the dynamics of the years of study (from the 1^st to 6^th year), a significant (р < 0.05) increase in body mass index (BMI) was revealed: from 20.81 ± 0.30 kg/m² to 22.45 ± 0.41 kg/m² in females; from 22.71 ± 0.65 kg/m² to 24.24 ± 0.54 kg/m² in males, respectively. Furthermore, an increase in the proportion of students with overweight in the BMI range ≥ 29 kg/m² was revealed. In the 6^th year, the proportion decreased of the students with excess fat in their diet (from 13.72 ± 0.09 to 8.32 ± 0.04% in females, p < 0.05; from 46.94 ± 0.28 to 6.72 ± 0.05% in males, р = 0.00039) and water deficit (from 72.41 ± 0.12 to 66.73 ± 0.21% in females, р < 0.05; from 71.85 ± 0.13 to 66.72 ± 0.21% in males, р < 0.05); the proportion of students, who followed healthy eating principles, increased (from 73.26 ± 0.64 to 81.39 ± 0.73% in females, р < 0.05; from 62.86 ± 0.52 to 65.71 ± 0.54% in males, р < 0,05). The Valeoscan program introduction into the educational process has made it possible to monitor the functional health indicators and nutritional characteristics of medical university students, which can be used to evaluate the effectiveness of the health-preserving technology being introduced.
