Abstract
Objective: The study was aimed at determining the characteristics and lifestyle choices of dietary supplement users and to assess knowledge, attitude, and practice related to dietary supplements in the health sciences students versus other individuals in Saudi Arabia. Methods: A descriptive cross-sectional, online questionnaire-based study was conducted on 351 participants (138 were health sciences students and 203 were not). The results were documented and analyzed using SPSS- version 22. Results: More than half of the participants consumed dietary supplements, 53.6% of the health sciences students versus 56.3% of the other individuals. Multivitamins were the most commonly used supplement in all participants (49%). Both groups believed that people might need dietary supplements more during specific times as pregnancy or recovery from diseases, with higher percentage in health sciences students than other people (43% versus 38%). Most of the students were somewhat aware about the facts concerning dietary supplements compared to others. Significant difference (P <= 0.05) was found concerning opinion and beliefs related to dietary supplements between the two groups. However, the health sciences students were not highly knowledgeable about the facts regarding supplements. Conclusion: The users of dietary supplements tend to incorporate these products into their lifestyles as part of a broader focus on healthy living. Many of health sciences students do not have accurate information about dietary supplements. It is important to strengthen the health science curriculum concerning this topic, with the aim of producing better-informed future professionals.
