INTRODUCTION: The outbreak of the disease caused by the novel coronavirus, SARS-CoV-2 named COVID-19 has spread throughout the world. The number of registered cases is increasing and almost no country or territory worldwide has been without any COVID-19 patient. The aim of this study was to examine the level of knowledge on the SARS-COv-2 and COVID-19 among medical students and to explore the differences in attitudes, practices and fear of COVID-19 among students with sufficient and students with insufficient knowledge. METHODOLOGY: The cross-sectional study among the 1,722 medical students was conducted through an online platform of the Faculty of Medicine, University of Belgrade. The instrument used was a questionnaire with sections on socio-demographic characteristics, knowledge, attitudes and practices towards COVID-19 and the Fear of COVID-19 scale. RESULTS: Total of 1576 (91.50%) students were in the sufficient knowledge group. The multivariate logistic regression analysis showed that there was a significant association between the sufficient knowledge on COVID-19 and female sex (OR = 1.70, 95% CI = 1.18-2.45), age (OR = 1.10, 95% CI = 1.02-1.18), considering the preventive measures enforced in Serbia as good (OR = 2.57, 95% CI = 1.18-5.56), wearing the surgical mask outside of the household in the past 14 days (OR = 1.87, 95% CI = 1.22-2.87) and score on Fear of COVID-19 scale (OR = 0.94, 95% CI = 0.91-0.98). CONCLUSIONS: Medical students showed good knowledge of COVID-19 and could be a part of the promotion of health education messages as a part of preventive measures.

OBJECTIVE: The present study aimed to identify the role of mother's education in the nutritional status of children aged 2-5 years in Serbia. DESIGN: Nationally representative population-based study. Age- and gender-specific BMI percentiles of children were analysed. In accordance with the WHO growth reference, children with BMI less than the 5th percentile were considered undernourished. Logistic regression was used to calculate the association between mother's education and other socio-economic determinants as possible confounders. SETTING: UNICEF's fourth Multiple Indicator Cluster Survey, conducted in both Roma and non-Roma settlements in Serbia. SUBJECTS: Children (n 2603) aged 2-5 years (mean age 3·05 years). RESULTS: Less than 5 % of children aged 2-5 years were undernourished. There were significantly more undernourished children among the Roma population, in the capital of Serbia and among those whose mothers were less educated. There were statistically significant differences according to mother's education in all socio-economic characteristics (ethnicity, area, region of living and wealth index). Mother's level of education proved to be the most important factor for child's nutritional status; place of living (region) was also associated. CONCLUSIONS: Mother's education is the most significant predictor of children's undernutrition. It confirms that investment in females' education will bring benefits and progress not only for women and their children, but also for society as a whole.

tors associated with, burnout among medical students can help develop evidence-based programs for the prevention of burnout The most commonly used questionnaire on burnout was developed by Maslach and it measures burnout in 3 dimensions: emotional exhaustion, depersonalization and a lack of personal accomplishment The main constraint as to the use of the Maslach Burnout Inventory (MBI) is that it was intended for the use among service professionals. Consequently, the Danish National Institute of Occupational Health developed the Copenhagen Burnout Inventory (CBI) with the aim of measuring burnout in different settings The concept behind the development of CBI was that burnout syndrome is not only associated with emotional exhaustion, but also with physical exhaustion, which develops in the personal sphere, the work sphere and in interactions with clients This concept has led to the development of 3 subscales of CBI (personal burnout, workrelated burnout and client-related burnout) While CBI can be used in different settings, including the student population, it was not specifically developed for students. The instruments for assessment purposes need to be reliable, but should also be especially adapted for the student population. Therefore, the Study Burnout Inventory (SBI) was developed based on the School Burnout Inventory and the Work Burnout Inventory [3], showing good reliability. To the best of the authors' knowledge, although studies regarding burnout syndrome were previously conducted in Serbia, MBI was most commonly used as the instrument Abstract Objectives: The aim of this study was to assess the validity and reliability of the Serbian versions of the Copenhagen Burnout Inventory (CBI) and the Study Burnout Inventory (SBI) among fifth-year medical students at 5 universities in Serbia. Material and Methods: The study included 573 fifthyear medical students at 5 universities in Serbia. The research instrument consisted of SBI and CBI. The reliability of these instruments was assessed using an internal consistency measure (Cronbach's ), an intra-class coefficient (ICC) and factor analysis. Results: Cronbach's for SBI was 0.83, including for exhaustion 0.73, for cynicism 0.70, and for inadequacy 0.48. The test-retest reliability (ICC) was 0.75. Cronbach's for personal burnout on CBI was 0.89, for the faculty-related burnout 0.86, and for the faculty-members-related burnout 0.92. Cronbach's for CBI was 0.93. The factor analysis for SBI showed 2 factors and for CBI 3 factors. Conclusions: This study revealed that the Serbian versions of both SBI and CBI could be used for the assessment of burnout in this population.
