This study aimed to explore the set of variables related to skeletal muscle mass (SMM) in both sexes, and to create age-and sex-related models of changes in SMM, using the most representative indicator of muscular status. Body composition was assessed in 8733 subjects (♀= 3370 and ♂= 5363), allocated into subsamples according to age: 18–29.9, 30–39.9, 40–49.9, 50–59.9, 60–69.9, and 70.0–79.9 years. Nine variables were used: protein mass, protein percent, protein mass index, SMM, percent of SMM, SMM index, fat-free mass, fat-free mass index, and protein/fat index. Univariate and multivariate analysis of variance (ANOVA and MANOVA) were used to determine between-and within-sex difference in all variables by age. Correlation analysis established the relationship between age and muscularity variables. Principal Component Analysis extracted the variables that loaded highest in explaining muscularity, while regression analysis determined the linearity of association between the age and indicators of muscular status. Variables SMMI and PSMM were extracted as the most sensitive to age, with SMMI being gender-independent while showing the parabolic and sinusoidal form of change as function of ageing in males and females, respectively; and PSMM being sex-dependent while showing a linear trend of decrease in both sexes. © 2020 by the authors.

Introduction/Objective Knowledge and practical skills in medical waste (MW) management are of equal importance for medical and dental doctors. The first comparative study on the knowledge and skills in the field of MW management among Belgrade students was conducted with the goal of examining whether students of medicine and dentistry are equally familiar with this extremely important field. Methods A cross-sectional study included 558 students of the sixth year of studies (430 medical and 128 dental students) who completed an anonymous semi-structured questionnaire to determine attitudes and knowledge on MW management. Results The majority of medical and dental students had no training in MW management (79.5% and 74.6%, respectively). Dental students use protective equipment more frequently than medical students (94.5% vs. 42%, p < 0.001). However, full vaccinal protection against hepatitis B is better among medical students compared to dental students (57.7% vs. 39.1%, p < 0.001). Complete knowledge on postexposal prophylaxis is better among medical students compared to dental students (44.5% vs. 13.3%, p < 0.001). However, dental students are more disciplined in reporting injuries (63.1% vs. 52.4%, p = 0.038). The students’ knowledge on primary separation of infectious waste (93% vs. 77.8%, p < 0.001) and used needles (80.3% vs. 70.4%, p = 0.007) is better among dental students compared to medical students’ correct answers. Conclusion Dental students show better knowledge on MW management and are more disciplined in using personal infection protection compared to medical students. The students support continued training on MW management and investigations on this topic. © 2019, Serbia Medical Society. All rights reserved.

Background: High levels of environmental noise may lead to psychological symptoms. The present study has hypothesized that personal listening device (PLD) use and a negative attitude to noise are significantly related to anxiety and/or depression. Methods: This is a cross-sectional study conducted on 431 six-grade students (35% male) at the Faculty of Medicine, University of Belgrade. All students completed the questionnaires related to socio-demographic data, noise/music exposure habits, behaviors related to PLD use, tinnitus, headaches, consumption of alcohol, coffee, energy drinks and cigarettes, YANS (Youth Attitude to Noise Scale), CES-D (The Center for Epidemiologic Studies Depression), and GAD–7 (Generalised Anxiety Disorder Assessment − 7 item scale) questionnaires. Results: There were 396 (91.9%) of investigated students who used PLD, with more frequent use among girls compared to boys (95.0% and 86.8%, respectively; p = 0.002). We found no significant relationship between the frequency of PLD use and depression and anxiety. However, continuous daily PLD use longer than 1 hour was significantly and positively related to depression (p = 0.006). Students with depression had a lower total YANS score compared to those without depression, indicating a more negative attitude toward noise (p = 0.042). Students with no difficulties to concentrate in noise and with a positive attitude to daily noises had about 37% lower chance to suffer from depression and anxiety, respectively. Conclusions: PLD use is common among medical students and may be associated with their mental health. Longer than 1 hour of continuous daily use of PLD may be positively related to depression. We also found a significant relationship between difficulties concentrating in noisy environments and depression, and between negative attitudes to daily noises and anxiety. © 2023 Noise & Health | Published by Wolters Kluwer - Medknow.
