The Prevalence of Healthy Lifestyle in Students in Europe: the Mediterranean Diet, Orthorexia Nervosa, Appropriate Physical Activity, Stress Perception, and Sleep Habits

Non-communicable diseases (NCDs) compose a substantial proportion of the global burden of diseases, posing a significant challenge in both high-income and low- and middle-income countries. In particular, certain lifestyle-related risk factors, such as unhealthy diet, physical inactivity, smoking, excessive alcohol consumption, and sleep deprivation are the leading risk factors, which place people at an increased risk of developing NCDs. On the other hand, a growing phenomenon of excessive concern about diet and health is emerging, and it is contributing to the development of a novel eating behavior disorder named orthorexia nervosa. According to recent studies, orthorexic behavior is very common among young adults and especially so in health-care professionals.

The main objective of this multi-center study is to explore and compare lifestyle habits among undergraduate medical students and other healthcare-related professions from different countries (Croatia, Lebanon, Italy, Poland, Spain, and Turkey). The goal is to obtain information on the presence of unhealthy habits in order to be able to intervene, offering the information needed for primordial disease prevention in this young and still healthy group of respondents, who are the health educators and role models of the future. The particular importance of this goal is to raise awareness of the problem of the ubiquitously present unhealthy lifestyles. Unfortunately, health-care students are not the exception regarding the prevalence of the unhealthy diet, sedentary behavior, sleep deprivation and high levels of psychological stress. Furthermore, the adoption of unhealthy lifestyle patterns in health-care workers, such as doctors and nurses, will have far-reaching negative consequences, in both their health and their patients' health. The results of this study will be used for identifying the needs and targets for intervention, enabling students to become a pillar of health education for their patients and the population in general.
