Knowledge, Attitudes Toward, and Acceptability of Genetic Modification among Western Balkan University Students of Life Sciences (AGREE Study).

BACKGROUND: There are still no data on the attitudes and acceptance of genetic modification (GM) food in European developing countries, such as the Western Balkan countries. The aim of the study was to assess the knowledge, attitudes, and acceptance of GM but also to shed light on the multifactorial process leading to acceptance of genetic modifications among Western Balkan students of life sciences. METHODS: In this cross-sectional study, the final study population sample was composed of 1251 university students. The instrument for data collection was a questionnaire consisting of 49 items composed of 5 sections taken from the literature. Attitudes toward GM were analyzed by using Q-mode factor analysis and principal component analysis was run for the assessment of perception of personal health risks. The acceptability of GM was analyzed in binary probit models assessing the acceptability of GM products in different areas of application with Q models, sociodemographic variables, perception of personal health risks factors, respondents' knowledge about biotechnology, gender, and age as explanatory variables. RESULTS: This study demonstrated that students of life sciences supported the implementation of GM in industry and medicine production but not in food production. Their acceptance was most influenced by 3 out of 5 attitude models that were identified (p < 0.0001). Regarding the perception of personal health risks, the factor "credence risks" was seen as a negative predictor of acceptance of GM in industry and food production (p < 0.05). The main knowledge predictor of rejecting GM was misconception, whereas real knowledge had no impact (p < 0.0001). CONCLUSION: The AGREE study provided the first rough picture of the knowledge, attitudes, and acceptance of GM in this area. Given the target population, it could be expected that the general population's acceptance of all observed elements, especially knowledge, would be lower.

Organizational commitment and job satisfaction among nurses in Serbia: a factor analysis.

BACKGROUND: One of the basic prerequisites of efficient organizational management in health institutions is certainly monitoring and measuring satisfaction of employees and their commitment to the health institution in which they work. The aim of this article was to identify and test factors that may have a predictive effect on job satisfaction and organizational commitment. METHODS: We conducted a cross-sectional study that included 1,337 nurses from Serbia. Data were analyzed by using exploratory factor analysis, multivariate regressions, and descriptive statistics. RESULTS: The study identified three major factors of organizational commitment: affective commitment, disloyalty, and continuance commitment. The most important predictors of these factors were positive professional identification, extrinsic job satisfaction, and intrinsic job satisfaction (p < .0001). Predictors significantly affecting both job satisfaction and organizational commitment were identified as well; the most important of which was positive professional identification (p < .0001). CONCLUSIONS: This study identified the main factors affecting job satisfaction and organizational commitment of nurses, which formed a good basis for the creation of organizational management policy and human resource management policy in health institutions in Serbia.

Validation of the Study Burnout Inventory and the Copenhagen Burnout Inventory for the use among medical students.

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 α), an intra-class coefficient (ICC) and factor analysis. RESULTS: Cronbach's α 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 α 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 α 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. Int J Occup Med Environ Health. 2021;34(6):737-45.

Relationship between the Manner of Mobile Phone Use and Depression, Anxiety, and Stress in University Students.

Objectives: There is insufficient evidence regarding the potential risk of mobile phone use on mental health. Therefore, the aim of this research was to examine the relationship between mobile phone use and mental health by measuring the levels of depression, anxiety, and stress among university students in Serbia and Italy. Methods: This cross-sectional study was carried out at two distinguished universities in Serbia and Italy from March to May of the 2015/2016 academic year and included 785 students of both genders. The questionnaire was compiled and developed from different published sources regarding the manner and intensity of mobile phone use, along with the Depression Anxiety Stress Scale (DASS 42) for measuring psychological health. The statistical analysis of the data included the application of binary logistic regression and correlation tests. Results: Statistical analysis indicates that anxiety symptoms are somewhat more present in younger students (odds ratio (OR) = 0.86, 95% confidence interval (CI): 0.76-0.96), in those who send more text messages SMSs (OR = 1.15, 95% CI: 1.11-1.31), and in those who browse the internet less frequently (OR = 0.84, 95% CI: 0.73-0.95). Stress is more common in students who make fewer calls a day (OR = 0.79, 95% CI: 0.64-0.97), as well in those who spend more time talking on the mobile phone per day (OR = 1.28, 95% CI: 1.12-1.56). The strongest predictor of high stress levels was keeping the mobile phone less than 1 m away during sleeping (OR = 1.48, 95% CI: 1.12-2.08). Conclusions: The results indicated that the intensity and modality of mobile phone use could be a factor that can influence causal pathways leading to mental health problems in the university student population.

[Knowledge, attitudes and use of dietary supplement among students of the University of Nis (Serbia)].

INTRODUCTION: Dietary supplements, being concentrated sources of vitamins, minerals and other substances with nutritional and physiological effects, are products that supplement the normal diet. The aim of this study was to determine the use, attitudes and knowledge on dietary supplements among students of the University of Nis, paying special attention to differences in responses between male and female students. MATERIAL AND METHODS: The study used the original questionnaire which was distributed to 330 students from the University of Nis. The sample was stratified by school, year of study and sex. Out of 330 questionnaires, 301 were classified as correct and they were further analyzed. RESULTS: Dietary supplements were used by 68.10% of the respondents. Females used dietary supplements more than males. Two or more products were most commonly used. Multivitamins were the most widely used products. The majority of respondents adhered to the declaration (77.07%). A small number had health damage (2.93%). More than half of the students stated that they were not properly informed about dietary supplements. The most common source of information was the media and friends. CONCLUSION: Health professionals and users of dietary supplements should be educated better on the use of these products in order to make the supplement use safe, controlled and rational.
