Adolescence is a period of intense development and maturation during which young people adopt different habits and attitudes. These habits and attitudes determine their lifestyle, which has an impact on their current but also future health. It is a crucial period for adopting a healthy lifestyle because habits are still changeable and it is very likely that they will remain in adulthood. Given that many studies conducted among this age group nevertheless indicated their involvement in many risky behaviors, the aim of this paper was to examine what the findings would be among health care students. Therefore, the study was conducted among 294 students of the Rijeka Medical School. Their subjective, general assessment of life habits, eating habits, physical activity habits, involvement in the consumption of addictive substances and attitudes towars the role of school and health professionals in promoting healthy living were examined. The largest number of students evaluated their life habits as healthy, and fully or partially agree that school and health professionals have an important role in promoting healthy living, which confirmed these hypotheses. Hypotheses about differences between students in alcohol and drug use by gender were rejected, while the hypothesis of cigarette consumption was partially and stress fully accepted. It was evident that there is no difference between eating habits between students of different directions while in the physical activity there is. Due to the characteristics of that age and susceptibility to influence, young people are exposed to many risk factors, however, through education and appropriate preventive measures, their effects can be partially reduced. It is essential that young people become aware of their own impact on their health and quality of life.
