EVALUATION OF THE INDICATORS OF THE MUNICH CHRONOTYPE QUESTIONNAIRE IN MEDICAL STUDENTS
The aim of the study was to assess the chronotype in the transition period of 2019 (March-May), taking into account the BMI of medical students living in the city of Vladikavkaz (43°01'00" N 44°41'00" E), North Ossetia-Alania. A voluntary survey of 270 medical students (210 girls, 60 boys) was carried out with the Munich Chronotype Questionnaire (MCTQ). The indices of the entire group were evaluated, separately for boys and girls on weekdays and weekends - the duration of sleep, the time of falling asleep, the middle of sleep, which determines the chronotype, and "social jetlag". Analysis of the data showed significant sex-based differences, the duration of sleep in the mixed group is shorter on weekdays, but for boys it is significantly less than for girls on weekends. The time of falling asleep in the mixed group was shifted to a later time (29 minutes); for girls - by 22 minutes, and for boys - by 51 minutes. In the mixed group, significant differences were found between the duration of sleep on weekdays and weekends (by 29%), the shift in the middle of sleep to the morning hours (by 1 h 36 min). Students have “slightly late” (girls) and “moderately late” defined chronotypes. The prevalence of "late" chronotypes among medical students is accompanied by low resistance to the social environment; a chronic difference between endogenous and external biorhythms leads to an increasing tension of adaptation, which forms dysregulatory disorders, and is a risk factor for the development of pathology of the NEIM system.
