10+ years’ experience with particular focus on planning, conducting, and evaluating research studies dealing with health and exercise, which also include clinical trials. As a sports and exercise scientist I use knowledge of how the body works to help people improve their health and sporting ability at large. However, I have also profound insight into physical anthropology, and I understand the complexity of how physical activity affect the human body and its composition; but, also into social anthropology that helps to understand the social side of the same issues. With a background as a Ph.D. from the University of Novi Sad and postdoc from the University of Ljubljana, as well as a teacher and research at the University of Montenegro, I have achieved the following key competencies: knowledge of teaching and the ability to design courses, project and data management, study design expertise, excellent communication skills, and dissemination skills in both written and oral etc. I currently hold several leading positions in the national and international projects, as well as leading roles and memberships in the governing bodies of professional and scientific organizations. My friends describe me as tenacious, detail oriented, and successful who is a very determined and highly motivated person. I do take my job seriously but I’m able to see things in perspective and believe I’m quite easy-going to work with. I am an optimist rather than a pessimist – but I am also a realist.
Background: The present study investigates the role of different sources of social support in the relationship of BMI and PA in an international sample of children and adolescents. Methods: Data included 170,211 adolescents (51.5% female), aged 10–16 (M = 13.6, SD = 1.64) from 37 European countries/regions and were retrieved from the 2013/14 Health Behaviour in School-aged Children (HBSC) international database. Results: PA levels in adolescents are lower for girls, decrease with age, and are lower for overweight and obese adolescents compared to underweight and normal-weight adolescents. Peer support and teacher support significantly predict PA (ORpeer = 1.11; ORteacher = 0.97) and vigorous PA frequency (ORpeer = 1.13; ORteacher = 0.94). Family support only affected vigorous PA frequency (OR = 1.03). Family support had a moderating effect on PA in overweight (ORfamily*BMI(overweight) = 0.94) and obese (ORfamily*BMI(obese) = 0.90) adolescents. Peer support had a moderating effect on vigorous PA frequency in obese (ORpeer*BMI(obese) = 1.08) adolescents. Teacher support had a moderating effect on PA (ORteacher*BMI(normal) = 1.05; ORteacher*BMI(overweight) = 1.09) and vigorous PA frequency (ORteacher*BMI(normal) = 1.07; ORteacher*BMI(overweight) = 1.08) in normal-weight and overweight adolescents. Conclusion: Social support helps adolescents to be active. Especially for obese adolescents, support by and relations with peers are important to reach a significant amount of PA.
