The purpose of the study was to analyze the level of physical health of medical students and assess the factors that affect it. Materials and methods. 230 boys and girls of the first year of the medical faculty were examined in M. I. Pirogov Vinnytsa National Medical University at the age of 17 to 22 years. According to outpatient cards and the results of the survey, all students were classified as "practically healthy" and did not go in for professional sports. Assessment of the level of physical health was carried out according to the method of quantitative express assessment of the level of somatic health (G. L. Apanasenko). The physical activity of students, the nature of their diet, the presence or absence of bad habits were determined by the method of questioning. Results and discussion. According to the results of an express assessment of the level of somatic health, it was found that out of 230 first-year students, a high level of physical health was not recorded at all, 4.3% had above average, 22.6% had an average level, 31.7% had below average and 41.3% of students had a low level of physical health. According to gender, the results of the students were divided as follows: with an above average level of physical health there were 3 (2.1%) girls and 7 (7.8%) boys; with an average level – 30 (21.4%) girls and 22 (24.4%) boys; with below average level – 44 (31.4%) girls and 29 (32.2%) boys and a low level of physical health was observed in 63 (45%) girls and 32 (35.6%) boys. Boys and girls with a level of physical health above average were excluded from the study due to the low representativeness of the sample (3 girls and 7 boys). The rest made up groups with average (30 girls and 22 boys), below average (44 girls and 29 boys) and low (63 girls and 32 boys) levels of physical health. The study of physical activity showed that only 40% of girls and 68.2% of boys with an average level of physical health were engaged in non-professional sports. With a decrease in the level of physical health, the number of girls and boys who wanted to go in for sports decreased (p<0.001). Analyzing the nutrition of young people in the first year of study, we can say that for most students it was irrational. Only 60% of girls and 59.1% of boys with an average level of physical health ate rationally. Deterioration of nutrition had a negative impact on the formation of physical health (p<0.05). 7.9% of girls and 40.6% of boys had bad habits with a low level of physical health; 6.8% of girls and 31% of boys – with below average and 6.7% of girls and 31.8% of boys – with an average level of physical health. Conclusion. The vast majority of students had average, below average and low levels of physical health. Motor activity, quality of nutrition, bad habits influenced the formation of physical health
