ЛАТЕНТНЫЕ ФАКТОРЫ КАЧЕСТВА ЖИЗНИ СТУДЕНТОВ, ОБУЧАЮЩИХСЯ ПО СПЕЦИАЛЬНОСТЯМ СРЕДНЕГО МЕДИЦИНСКОГО ПЕРСОНАЛА

The quality of life of students receiving the profession of a secondary medical specialist is studied. Latent factors that have a greater impact on the quality of life are identified. The quality of life of students according to the first factor is determined by the scales of the psychological component: for young women - Resilience, for young men - Mental health

ХРОНОТИП ОБУЧАЮЩИХСЯ ВЫСШЕЙ ШКОЛЫ В УСЛОВИЯХ ИЗМЕНЕННОГО ФОТОПЕРИОДА СЕВЕРНОГО РЕГИОНА

A chronotype resistant to changes in the photoperiod was determined for students in the North. In the men's and women's groups, the preferred bedtime, well-being in the evening and when performing physical exercises differed. Morning and evening preferences in the organization of life activities in young men are less susceptible to exogenous influences than in girls.У студентов северного вуза установлена устойчивость хронотипа к изменению фотопериода. В мужской и женской группах отличалось предпочитаемое время отхода ко сну, самочувствие в вечернее время и при выполнении физических упражнений. Утренне-вечерние предпочтения в организации жизнедеятельности у юношей менее подвержены экзогенным воздействиям, чем у девушек

СЕЗОННЫЕ ОСОБЕННОСТИ ПРОФИЛЯ ФУНКЦИОНАЛЬНОЙ АСИММЕТРИИ У ПРЕДСТАВИТЕЛЕЙ РАЗНЫХ БИОРИТМОЛОГИЧЕСКИХ СТЕРЕОТИПОВ

The aim of the study was to investigate functional brain asymmetry in youths and girls depending on the biorhythmological stereotype in different seasons of the year. Differences are established in the degree of activation of the cerebral hemispheres of the brain depending on gender, season of the year, biorhythmic patterns. In the winter season, in groups of students identified a large activation of the right hemisphere. In young woman, the predominance of right hemisphere activity was more pronounced in the arrhythmic chronotype. In the spring season, young men with arrhythmic chronotype showed signs of activation of the left hemisphere, the «owls» was symmetrical profile. In young women in the spring observed increased activation of the right hemisphere, less pronounced in «pigeons».Цель - исследование функциональной асимметрии головного мозга у юношей и девушек в зависимости от биоритмологического стереотипа в разные сезоны года. Установлены различия в степени активации больших полушарий головного мозга в зависимости от пола, сезона года, биоритмологического стереотипа. В зимний сезон в группах студентов определили бо̀льшую активацию правого полушария. У девушек преобладание активности правого полушария было более выражено у аритмичного хронотипа. В весеннем сезоне у юношей с аритмичным хронотипом обнаружили признаки активации левого полушария, у «сов» был симметричный профиль. У девушек весной наблюдали усиление активации правого полушария, в меньшей мере выраженное у «голубей»

INtersystem interrelations of functional parameters and psychosocial characteristics of students of medical university in the north

The aim of the study is a possibility justification of the functional state correction of students in the learning environment through development of adaptive behavior skills in stress and increase of subjective evaluation of life quality. Methods: research and analysis of cardiac rhythm variability parameters, functional state of the central nervous system, daily monitoring of heart rate and blood pressure, indicators of life quality associated by health condition, features of coping behavior among students of the Khanty-Mansiysk State Medical Academy (n = 96). The structure of canonical roots was identified by means of Pearson's pair correlations. The first (R1 = 0.75; p < 0.001) and second (R2 = 0.72; p = 0.004) canonical roots proved to be statistically significant. Results. The results of the canonical correlation analysis between physiological parameters and biosocial characteristics (behavior in stress and life quality self-esteem associated by health condition) were given in students of the northern medical establishment. The indicators of variation chronoreflexometry correlated to a greater extent with the choice of coping behavior; the three main styles of coping had significant factor loading (r = 0,438-r = 0,558). Parameters of variation pulsometry, mesors of heart rate and systolic blood pressure were the most correlated with life quality self-esteem among physiological parameters; the highest factor loadings were in the scales of PF ( r = 0.637) and RE (r =-0.455). Conclusion: the revealed relations substantiate the possibility of the physiological state correction in students of higher school through increasing its subjective well-being and the formation of adaptive behavior in stress. © 2018 Ekologiya Cheloveka (Human Ecology).

Factor analysis of hemodynamics daily parameters in students of the Northern Medical University

The purpose was to find out the hidden common factors characterizing the relationship between the parameters of daily hemodynamics in students of the northern medical university. Methods. A factor analysis of hemodynamics data obtained during the daily monitoring of arterial pressure and heart rate in students of Khanty-Mansiysk State Medical Academy (35 boys and 61 girls) was carried out. Results. The analysis revealed two factors in groups. According to the first factor, the mesor factor loading of the index of functional changes (r = 0,833) and the daytime values of the IFI (r = 0,923) and the IAD DB (r = 0,708) achieved significant values in the young men. In the girls: SAD (r = 0,862), DBP (r = 0,767) and IFI (r = 0,919), daily SBP values (r = 0,889), DBP (r = 0,867), IFI (r = 0,942), IV DBP (r = 0,713) (total dispersions are 34,37 % and 39,05 %). The second factor included night hemodynamic parameters in both groups. The young men had: IFI night (r = 0,808), SAD night. (r = 0,813), DBP overnight. (r = 0,892), IV SBP overnight. (r = 0,766), IV DBP at night. (r = 0,778), night decrease of SBP (r = –0,822) and DBP (r = –0,806), in girls: SAD night. (r = 0,776), DBP overnight. (r = 0,836), IV DBP of night. (r = 0,740), SB SBP (r = –0,797) and NS DBP (r = –0,865) (the total variance is 23,04 % and 17,68 %). Conclusion. Differences were found in the structure of the relationship of hemodynamic indices associated with gender. The first factor was formed by daily and average daily hemodynamic indices; in girls its composition is determined by a large number of variables 7 against 3 in boys. The second factor was formed by the night values of hemodynamic indices in both groups. Day and night indices of hemodynamics did not correlate. © 2018 Northern State Medical University.
