Introduction: The relevance of scientific research is determined by the significant importance of lifestyle in preserving and strengthening the health of the population especially young people what determines the future of any society. Among the numerous youth lifestyle characteristics, particular attention is paid to behavioral factors, including the presence of bad habits. Data of scientific publications indicate a significant prevalence in student environment of tobacco-smoking, consumption of alcohol and other manifestations of unhealthy behavior, which are powerful factors of the risk of developing non-communicable diseases, injuries and other health disorders. One of the most important tasks is the formation and establishment of a healthy lifestyle among medical students, because in the future they will not only treat patients, but also carry out professional activities for the prevention of diseases and risk factors for their development, correcting and overcoming already existing risk factors. Doctors must be conscious supporter of healthy lifestyle and serve as a role model for their patients. The aim: To identify the features of prevalence of tobacco use, alcohol and energy drinks among medical students and justify ways of counteraction based on the results of own sociological research, scientific literature, WHO program and strategic documents. Materials and methods: An anonymous questioning was covered 948 students of institutions of higher medical education including 34.5% of men and 65.5% women. It had been used bibliosemantic, sociological and medical-statistical methods. The information base of the study included program and strategic documents of WHO, sources of scientific literature, data of own research. Statistical processing of the obtained results was carried out using generally accepted medical statistics methods using licensed programs (SPSS, STATA, Statistica 10.0 and MS Excel XP). Results: The results of the study indicate a sufficient significant prevalence in the student environment of tobacco, alcohol and energy drinks. Third part of students consumes tobacco, of which 15.2 per 100 respondents are regular smokers with experience, 9.3 per 100 respondents smoked 10 or more cigarettes a day. A new negative trend is the use of hookah by almost half of the interviewed students and consumption of electronic cigarettes (8.5 per 100 respondents), what must be taken into account when substantiating counteraction ways. Three quarters of the respondents consume alcohol. Despite the prevailing consumption of low-alcohol beverages and wine by respondents, every seventh of the respondents consumes strong drinks. The reason for the worrying is the fact that 13.6 ± 4.7 in 100 respondents combine the consuming of energy drinks with alcohol. By 4.9 per 100 students interviewed, energy drink increases the desire to drink alcohol. Conclusions: The revealed connection between tobacco, alcohol and energy drinks consumption among medical students proves the need for an integrated approach to reduce the prevalence of risk factors in the context of a healthy lifestyle.

Summary. One of the phenomena of personal deformation is emotional burnout (EB). Emotional burnout syndrome (EBS) can occur during studying in institution (university) and become an obstacle in its process. EBS affects up to 40% (students) of young people studying. Components of learning: social comparison and evaluation, dissatisfaction with the process and the result of learning, feelings of injustice in the assessment of knowledge, unjustified hopes, difficulties in communication are factors of emotional burnout. Aim. To determine the presence and influence of negative factors on the possibility of emotional burnout in students of higher educational institutions. Materials and methods. A one-step (transverse) study was conducted. Social networks popular among students – Telegram, Instagram – were chosen to distribute the questionnaire. In particular, the survey form was sent in such chats as NMU, KT-18, LNTU students, conversations of students of NMU named after O.O. Bogomolets, National University “Lviv Polytechnic” and Borys Hrinchenko Kyiv University. Results and discussion. When analyzing the data according to the specialization of the higher educational institution and the year of study, attention is drawn to the increase in the percentage of students studying medicine, dentistry, pharmacy according to the years of study who force themselves to work (learn subjects) despite fatigue. These are the students of second grade – 8.33%, third – 23.86%, and fifth one 25%. The number of such students studying philology tends to decrease from 100% in the third study year to 25% in the fourth one. The number of third-year students who try to study despite fatigue, in the field of economics, philology and management and marketing is greater than among students who study in the field of medicine, dentistry and pharmacy. 33.3%, 100%, 28.5% against 23.8%, respectively. Conclusions. Based on the results obtained, it can be concluded that with each study year, the percentage of students who feel depressed due to learning difficulties, who feel tired and unwilling to study in senior grades, is growing. It was also detected that in senior grades among students who experience chronic fatigue, the use of psychoactive substances is highly spread. Among the surveyed students, there is a high percentage of probable risk of development of the syndrome of emotional burnout (SEB). It is specified that the percentage of probable risk of SEB increases with each year of study. It was found that medical students tend to feel chronic fatigue and the need for additional motivation to study earlier than other students. Computer science students were the least likely to develop emotional burnout.

The aim: To determine the features and trends of dermatovenerological health of population; to identify conditions and problems of providing dermatovenerological care. Materials and methods: Bibliographic, epidemiological, medico-statistical, sociological methods were used. Scientific literature, data from the Center of Medical Statistics of the Ministry of Health of Ukraine concerning population health and dermatovenerological establishments activity on 2000-2019, data of authors` own sociological researches on opinion of dermatovenerological profile experts about available problems and ways of their decision were analyzed. Results: A long-term tendency towards a decrease in the incidence of skin and subcutaneous tissue diseases by 8,6% during 2000-2017 and the incidence of venereal diseases during 2000-2019 was revealed (for syphilis – by 15,5 times, gonorrhea – by 6,8 times). At the same time, during 2014-2019 there was an increase in the incidence of atopic dermatitis by 3,6%, of contact dermatitis – by 5,2%, of trichophytia and microsporia by 22,6%, as well as increase in the prevalence of psoriasis – by 6,0%. The incidence of sexually transmitted diseases remains significant. Trends in recent years indicate a deterioration in dermatological health and an increasing need for medical services. During healthcare reforming over the course of nineteen years there was a reduction in the amount of dermatovenerologists and their number per population by 31,5%, the amount of dermatological institutions – by 2,6 times and beds – by 3,9 times. According to 18,6±3,1 per 100 surveyed respondents, the availability of dermatovenerological care to the population is low, and its deterioration in the COVID-19 pandemic was confirmed by 80,1±4,0. Some factors that negatively affect the quality of medical services have been identified: insufficient amount and quality of medical equipment (57,1±4,0 per 100 respondents), insufficient opportunity for continuous professional development (34,0±3,8); lack of computers (30,8±3,7); lack of motivation to improve the quality of work (28,8±3,6). The priority measures that need to be taken to improve dermatovenerological medical services have been identified. Conclusions: The study of dermatovenerological profile experts` opinion regarding the current state of the dermatovenerological service, human resources, the availability and quality of the services made it possible to identify a number of organizational and administrative problems as well as to prioritize activities on providing dermatovenerological care to the population in the context of healthcare reform and COVID-19 pandemic.
