Background: The aim of this study was to assess the knowledge and attitude of medical students in relation to cardiovascular disease (CVD) risk factors as well as to assess the impact of medical education on their knowledge and recognition of the importance of implementation of preventive measures. Methods: This cross-sectional study included 514 students in the second year of studying at the Faculty of Medicine in Belgrade, Serbia (younger students response rate 79.57%) and 511 students in the last year of education (older students response rate 90.21%). For data collection, an anonymous self-administered questionnaire was used, which included two types of questions about CVD risk factors and questions about the student’s attitude. Results: Older students knew significantly more about CVD risk factors than students who were at the beginning of their medical studies; however, more than half of the older students did not know the correct answers about CVD risk factors. The only exceptions were questions about “bad” and “good” cholesterol, metabolic syndrome (MSy) and lipid lowering therapy in high risk subjects. Physical inactivity, obesity, type 2 diabetes, smoking and hypertension were not ranked highly enough as important CVD risk factors. Compared groups of students did not significantly differ in attitude scores. The majority of them recognized CVD as the leading cause of death, had normal weight and knew their own blood pressure. Conclusion: Knowledge of medical students from Belgrade about CVD risk factors should be improved. © 2017, Springer-Verlag Wien.

Objective The present study aimed to compare different indicators of obesity in the Serbian adult population. Design Cross-sectional study. A stratified, two-stage, national-representative random sampling approach was used for the selection of the survey sample. Data sources were questionnaires created according to the European Health Interview Survey questionnaire. Measurements of weight, height and waist circumference (WC) were performed using standard procedures. Anthropometric measures included BMI, WC and waist-to-height ratio (WHtR). Setting Data for the study were obtained from the 2013 National Health Survey, performed in line with the EUROSTAT recommendations for performance of the European Health Interview Survey. Subjects Adults aged ≥20 years. Results According to BMI, out of the whole studied population (12 460 adults of both sexes) 2·4 % were underweight, 36·4 % overweight and 22·4 % obese. Using WC and WHtR as measures of adiposity showed that 22·5 % and 42·8 % of participants were overweight and 39·8 % and 25·3 % were obese, respectively. Men and women differed significantly in all variables observed. Overweight was more frequent in men and obesity in women regardless of adiposity measure used. Conclusions In spite of strong correlations between BMI, WC and WHtR, substantial discrepancies between these three measures in the assessment of overweight and obesity were found, especially in some age groups. Which of these anthropometric measures should be used, or whether two or all three of them should be applied, depends on their associations with cardiovascular or some other disease of interest.

Background: This was a psychometric validation of the short Chronic Venous Disease Quality of Life Questionnaire (CIVIQ-14) as quality of life (QOL) instrument for chronic venous disease (CVD) patients. Methods: Patients aged >18 years who had CVD in CEAP C stages C0s to C6 were included in the study. Diagnosis was made by general practitioners according to CVD symptoms and visual examination of the lower extremities. QOL was assessed with the self-administrated CIVIQ-14. The reliability, construct, and convergent validity of the CIVIQ-14 was estimated as well as QOL of CVD patients according to CEAP C stages. Results: The study comprised 2260 subjects who fully completed the CIVIQ-14. CIVIQ-14 had a high level of reliability, construct, and convergent validity, but the structure of its three dimensions (pain [P], physical [PHY], and psychological [PSY]) was suboptimal. After adjustment for age, body mass index, and number of CVD symptoms, CIVIQ -14 global, P, PHY, and PSY scores showed significant progressive reduction of QOL from CEAP class C0s to C6. These differences were present in both sexes. The progressive impairment of the QOL involved primarily the pain and the physical items. For all CEAP C classes, the P and PHY scores were lower than the PSY scores. Global scores for men and women were: 76.7 and 73.9 for C 0s; 75.5 and 70.6 for C1; 67.8 and 64.5 for C2; 68.3 and 61.6 for C3; 60.7 and 54.6 for C4; 49.5 and 50.2 for C5; and 41.3 and 46.7 for C6. Conclusions: CVD in the lower extremities has a substantial effect on both physical and psychologic aspects of QOL, the physical aspects of QOL (P and PHY items) being more important. CIVIQ-14 is valuable in assessing QOL in CVD patients. Further investigations are necessary to confirm the stability of its two dimensions. © 2013 Society for Vascular Surgery.© 2013 by the Society for Vascular Surgery.
