Background: Despite the numerous functions of vitamin D, there are still billions of people worldwidewho have vitamin D deficiency or insufficiency, and the highest prevalence is in the Middle East, mostly females.
Aim of The Study: This study aimed to assess the knowledge and behaviors of applied medical science female students regarding vitamin D. Participants and methods: A cross- sectional study was conducted at the Faculty of Applied Medical Sciences- Umm Al-Qura University. An electronic questionnaire was assigned for (156) students from female section and chosen from an age group (18-22 years) to assess their vitamin D knowledge and attitudes. Data analysis was done using the Statistical Package of the Social Science (SPSS) version 20, using frequency and chi-square test. A p-value less than or equal to 0.05 was considered significant.
Results: About 57% of the students were not aware that the overuse of sunscreen could block the ultraviolet rays from reaching the skin, thus decreased production of vitamin D. The overall knowledge of the students about vitamin D sources (fortified milk, mushrooms and eggs) was decent.
Conclusion: the students had a good background of vitamin D functions, sources, and deficiency symptoms but wasn't reflected on their behavior, this gap between their knowledge and their lifestyle must be filled through health education for better health.
