Objectives: To assess the general (non)knowledge of students of the Faculty of Dental Medicine and Health in Osijek regarding the side effects of steroid use. Study Design: Cross-sectional survey. Participants and Methods: Students of the Faculty of Dental Medicine and Health in Osijek. Results: The results indicate important knowledge about the connection between physical activity and attitudes towards steroids. First, individuals who participate in sports more often have a better knowledge of steroids, their uses and failures compared to those who are less or not physically active. This suggests a direct relationship between frequency of physical activity and education about steroids. Second, people who are more physically active, are more exposed to the use of steroids. This may be due to a greater presence of steroids in sports or a greater motivation to achieve sporting goals with steroids. Also, individuals who engage in physical activity more often are aware of the long-term consequences of steroid use, which increases awareness of potential risks. Moderate recreational athletes often perceive steroids as a serious problem in sports, which encourages awareness and prevention. Also, people who engage in physical activity more often believe that they are sufficiently informed about the side effects and risks of steroids, but students need to be better educated about them. This implies the need for stronger educational programs and campaigns aimed at this population. Finally, people who engage in physical activity are better acquainted with the methods of preventing the use of steroids, which indicates the importance of education and information in reducing the use of steroids in sports. Conclusion: The results emphasize the importance of recognizing the connection between physical activity and use, recognizing side effects, and preventing the use of steroids in fitness and sports.
