Pedagogical work, especially with preschool children, is one of the most stressful professions, and the incidence of stress-related illnesses among preschool teachers is higher than in the general population. The aim of this cross-sectional study, conducted between October 2018 and April 2019, was to examine the prevalence of the burnout syndrome in a representative sample of 482 preschool teachers in Serbia and the factors associated with it. For this purpose, the participants completed a questionnaire composed of six sections: the socio-demographic and socio-economic characteristics, health and lifestyle characteristics, workplace and employment characteristics; Copenhagen Burnout Inventory (CBI); Beck Depression Inventory (BDI), and the Zung Self-Rating Anxiety Scale (SAS). The frequency of the total burnout was 27.1 %. The frequency of burnout on the CBI was 25.4 % for personal burnout, 27.0 % for work-related burnout, and 23.4 % for client-related burnout. Multivariate logistic regression analysis with total burnout as an outcome variable showed that being single (OR: 0.18; 95 % CI: 0.05-0.58), having poor (OR: 6.05; 95 % CI: 1.05-34.91), or average (OR: 3.60; 95 % CI: 1.57-8.25) self-rated health, not having didactic/play tools (OR: 2.71; 95 % CI: 1.21-6.04), having a higher score on the BDI (OR: 1.19; 95 % CI: 1.09-1.29) or SAS (OR: 1.10; 95 % CI: 1.03-1.18) was significantly associated with the total burnout among our participants. Our study shows the worryingly high prevalence of the burnout syndrome among preschool teachers in Serbia and points to its association with mental health issues, depression, and anxiety. © 2024 Sciendo.

Objectives: Vaccine hesitancy presents one of the critical constraints in combating COVID-19 pandemic. The aim of this study was to develop and validate an instrument for measuring factors that contribute to COVID-19 vaccine hesitancy. Methods: The key constructs in the study instrument were factors that constitute the “3C” model of vaccine hesitancy: Confidence, Complacency and Convenience. Using a cross-sectional, online survey design, the 8-item COVID-19 Vaccine Hesitancy Questionnaire was administered to a sample of 667 adult citizens of Serbia in December 2020. We used confirmatory factor analysis to investigate the model that assumes three latent variables. To ensure that the instrument measures the same constructs in different groups, the measurement invariance examination was conducted. To examine criterion validity, Spearman’s correlation was applied to determine the association between the instrument total score and the single-item measuring the likelihood of getting vaccinated against SARS-CoV-2. Results: Confirmatory factor analysis established the three-factor structure, with subscales fitting within the “3C” model of vaccine hesitancy comprising confidence, convenience and complacency. The full scalar invariance was found across gender, and the partial scalar invariance was achieved for the age, region and education level. A higher level of the COVID-19 vaccine hesitancy was associated with the lower likelihood to get vaccinated against the SARS-CoV-2 virus. Conclusion: Our scale is brief and consistent, maintaining a good fit across key socio-demographic subgroups. This result implies that the scale could be useful for quick assessment of COVID-19 vaccine hesitancy in various target populations. © 2022, Czech National Institute of Public Health.

Objective: The novel coronavirus (SARS-CoV-2) has had an influence on almost the entire world and has become a major public health problem. Many countries have introduced measures that restrict the movement of the population and that may negatively influence the physical activity (PA) levels. The aim of this study was to examine the factors associated with changes in PA in Serbia during the COVID-19 outbreak. Methods: The cross-sectional study was conducted from the 9th through the 13th of April 2020. A total of 340 people, all contacted using Viber, were invited to participate in the study. The study instrument was a questionnaire that gathered information regarding social characteristics, PA during the outbreak, PA before the outbreak, and fear of COVID-19. Results: A total of 50 participants (14.7%) had low levels of PA in the 7 days prior to the study, while 133 (39.1%) had moderate and 106 (31.2%) had high levels of PA. The participants with high levels of PA had significantly higher energy expenditures before than after the COVID-19 outbreak (P <.001). There were no significant differences between the participants with different levels of PA in the scores on the Fear of COVID-19 scale (low: 13.4 ± 5.2; moderate: 12.6 ± 4.4; high: 13.8 ± 5.5; P =.204). Conclusion: One-sixth of the participants had low PA levels, and as restrictive measures are still in place in many countries, the lack of PA in high proportions of the general population may cause significant public health concerns.

Background: The benefits of physical activity during pregnancy include lower maternal weight gain, a lower likelihood of gestational diabetes, low back pain, preeclampsia, preterm delivery, caesarian delivery, and macrosomia. This study aimed to examine the factors associated with insufficient leisure-time physical activity (LTPA) during the first trimester. Methods: A cross-sectional study was conducted at the Clinic for Obstetrics and Gynecology of Clinical Center of Serbia, Belgrade, between January and June of 2018. The final analyses included 162/175 pregnant women. The questionnaire was used to obtain social characteristics, pregnancy, and lifestyle characteristics (Pregnancy Risk Assessment Monitoring System—PRAMS), pre-pregnancy LTPA (International Physical Activity Questionnaire—IPAQ), and LTPA during the first trimester (Pregnancy Physical Activity Questionnaire—PPAQ). Women were classified into two groups of sufficient and insufficient LTPA during the first trimester based on the recommendations of the World Health Organization. Multivariate logistic regression analysis was applied. Results: A total of 27.2% of the women had insufficient LTPA during pregnancy. Insufficient LTPA during pregnancy was associated with <12 years of education (OR: 2.3, 95% CI: 1.05–5.04), self-rated financial status as poor (OR: 0.34, 95% CI: 0.14–0.79), and hours spent walking before pregnancy (OR: 0.87, 95% CI: 0.77–0.99). Conclusions: Our results can help direct health care professionals advice for women who are planning pregnancy towards walking as it seems to be sustained during pregnancy. © 2020 by the authors.

Background: Certain lifestyle characteristics, such as dietary patterns, physical activity, and maintenance of recommended body weight, low-risk alcohol consumption and non-smoking are associated with the lower likelihood for the development of chronic-non communicable disease in the general population. These lifestyles are called health promoting behaviors (HPBs). We aimed to examine the prevalence of the HPBs among the women of reproductive age in Serbia and the factors associated with the compliance with four or more of these behaviors. Methods: The study was the secondary analysis of the data from the National Health survey in Serbia from 2019 that examined social, health status, mental health (using PHQ-8) and lifestyle characteristics of the general population in Serbia. Results: The prevalence of compliance with four or more HPBs was 22%. Among the HPBs the most frequent was a non-risky alcohol consumption reported by 2585 participants (99.2%), followed by normal weight (201869.2%) and non-smoking (1469-69%), daily fruit and vegetables intake (969-33.2%) and sufficient aerobic PA (216-7.9%). Multivariate logistic regression analysis with four or more HPBs as an outcome variable showed that the association of compliance with four or more HPBs with tertiary education (OR 1.91, 95% CI: 1.32-2.76) use of prescription medications (OR: 0.62, 95% CI: 0.44-0.87) and score on PHQ-8 (OR: 0.88, 95% CI: 0.79-0.98). Conclusion: There is a need for deeper promotion of health-related behaviors among all educational and vocational groups, including health promotion activities at the primary health care level, which is available to the entire population. © 2024 Todorovic et al.

Citations are an important, but often overlooked, part of every scientific paper. They allow the reader to trace the flow of evidence, serving as a gateway to relevant literature. Most scientists are aware of citations' errors, but few appreciate the prevalence of these problems. The purpose of the present study was to examine how often frequently cited papers in biomedical scientific literature are cited inaccurately. The study included an active participation of the first authors of included papers; to first-hand verify the citations accuracy. Findings from feasibility study, where we reviewed 1540 articles containing 2526 citations of 14 most cited articles in which the authors were affiliated with the Faculty of Medicine University of Belgrade, were further evaluated for external confirmation in an independent verification set of articles. Verification set included 4912 citations identified in 2995 articles that cited 13 most cited articles published by authors affiliated with the Mayo Clinic Division of Nephrology and Hypertension. A citation was defined as being accurate if the cited article supported or was in accordance with the statement by citing authors. At least one inaccurate citation was found in 11 and 15% of articles in the feasibility study and verification set, respectively, suggesting that inaccurate citations are common in biomedical literature. The most common problem was the citation of nonexistent findings (38.4%), followed by an incorrect interpretation of findings (15.4%). One-fifth of inaccurate citations were due to chains of inaccurate citations. Based on these findings, several actions to reduce citation inaccuracies have been proposed. © 2021 The Author(s).

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.

The aim of this study was to examine the differences in pregnancy complications, delivery characteristics, and neonatal outcomes between women with type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM), and gestational diabetes mellitus (GDM). This study included all pregnant women with diabetes in pregnancy in Belgrade, Serbia, between 2010 and 2020. The total sample consisted of 6737 patients. In total, 1318 (19.6%) patients had T1DM, 138 (2.0%) had T2DM, and 5281 patients (78.4%) had GDM. Multivariate logistic regression with the type of diabetes as an outcome variable showed that patients with T1DM had a lower likelihood of vaginal delivery (OR: 0.73, 95% CI: 0.64–0.83), gestational hypertension (OR: 0.47, 95% CI: 0.36–0.62), higher likelihood of chronic hypertension (OR: 1.88, 95% CI: 1.55–2.29),and a higher likelihood ofgestational age at delivery before 37 weeks (OR: 1.38, 95% CI: 1.18–1.63) compared to women with GDM. Multivariate logistic regression showed that patients with T2DM had a lower likelihood ofgestational hypertension compared to women with GDM (OR: 0.37, 95% CI: 0.15–0.92).Our results indicate that the highest percentage of diabetes in pregnancy is GDM, and the existence of differences in pregnancy complications, childbirth characteristics, and neonatal outcomes are predominantly between women with GDM and women with T1DM. © 2022 by the authors.

Background: The incidence of nosocomial infections caused by multi-drug- and extended-drug resistant strains of Acinetobacter is constantly increasing all over the world, with a high mortality rate. We analyzed the in-hospital data on the sensitivity of Acinetobacter baumannii isolates and correlated them with antibiotic treatment and clinical outcomes of nosocomial infections over a 17-mo period. Methods: Retrospective analysis was performed at the Clinical Center "Bezanijska kosa," Belgrade, Serbia. Microbiologic data (number and sensitivity of A. baumannii isolates) and clinical data (medical records of 41 randomly selected patients who developed nosocomial infection caused by A. baumannii) were matched. Results: Acinetobacter baumannii, detected in 279 isolates and obtained from 19 patients (12% of all samples), was resistant to almost all antibiotics tested, including carbapenems, with the exception of colistin and tigecycline. It was obtained most often from the respiratory tract samples. Empiric treatment of the nosocomial infections (pneumonia in 75% of cases) involved cephalosporins, metronidazole, and carbapenems (80%, 66%, and 61% of patients, respectively), whereas tigecyclin and colistin were used primarily in targeted therapy (20% and 12% of patients, respectively). The mortality rate of patients treated empirically was significantly higher (p < 0.01), reaching 100% in the elderly. Conclusions: Nosocomial A. baumannii infections represent a significant clinical problem because of their high incidence, lack of susceptibility to the most commonly used antibiotics, and the often inappropriate treatment, which favors the development of multi-drug-resistant strains. © Mary Ann Liebert, Inc. 2016.

BACKGROUND: In a view of sex work being a sexual behavioural activity, the main objective of our research was to explore the sexuality of sex workers in Serbia regarding to intensity of their sexual arousability. SUBJECTS AND METHODS: The research was conducted on 30 sex workers and 30 controls of randomly selected social and demographic characteristics, without any signs of psychiatric morbidity. For the evaluation of the intensity of sexual arousability, SAI (Sexual Arousability Index) questionnaire was used. RESULTS: The analysis of the main total scores of the SAI for the sex workers and control participants showed no statistically significant difference in the overall intensity of arousability (p>0.05). However, item by item analysis of the questionnaire showed qualitative difference in sexuality between sex workers and controls, related to certain aspects of sexuality. CONCLUSIONS: These findings allow the space for further research in the way of identifying origins of qualitative issues in the sexual profile of sex workers, in correlation to women who are not sex workers, i.e. whether they had been result of potential biological, specific psychodynamic factors, or have been formed as a result of the direct influence of the sex work.

Introduction: Burnout syndrome is being increasingly recognized as a factor that affects the health status and is being examined among different professional groups. Consequently, there is a need for a reliable and valid instrument for its examination. Teachers are emerging as a professional group of interest in the area of burnout research, so the aim of this study was to assess the validity and reliability of the Serbian version of Copenhagen burnout inventory among teachers at preschool institutions in Serbia. Materials and Methods: This research was conducted as a cross-sectional study between October 2018 and April 2019 on a nationally representative sample of preschool teachers in Serbia. The internal consistency of the scale was assessed using Cronbach’s alpha, and the construct validity was examined using exploratory (EFA) and confirmatory factor analyses (CFA). Results: The average score on total burnout was 39.1 ± 17.0, while the average score per scales on the Copenhagen burnout inventory was: 41.3 ± 18.7 for personal burnout, 41.2 ± 15.9 for work-related burnout, and 34.7 ± 22.0 for client-related burnout. The Cronbach’s alpha for the entire scale was 0.936, the Cronbach’s alpha for the personal burnout scale was 0.906, and the Cronbach’s alpha for the work-related burnout scale was 0.765, while the Cronbach’s alpha for the client-related burnout scale was 0.901. The EFA for the CBI showed three factors. The factor loadings varied from 0.575 to 0.859. The three factors explained 67.17% of the variance. Conclusions: Our study showed that the three-factor Serbian version of the Copenhagen burnout inventory can be used for the assessment of burnout syndrome among teachers. © 2021 by the authors.
