Abstract: ABSTRACT: Background: Vitamin D deficiency is currently recognized as a global epidemic and has been linked to many diseases. According to recent studies in Saudi Arabia showed a high prevalence of Saudi population having vitamin D deficiency. Objectives: The objective of this project was to find out how common vitamin D grade is and to look at the relationship between body fat proportion and vitamin D status among female university students. Methods: University female students were the subject of a cross-sectional study. After obtaining their permission, s le of 300 students were selected to participate. Weight, height and waist circumference were taken. Body composition were analyzed by using bioelectrical impedance analysis (BIA). Bloodspot testing was used to determine 25 hydroxyvitamin D (25(OH) D) level. Results: this research found significant relationship between vitamin D deficiency and the body fat percentage. Overweight and obese people have lower vitamin D levels than slimmer people. The relationship between the two variables is medium strong and inverse meaning that students with high proportion of body fat have decreased levels of vitamin D and vice versa. This finding is supported by the linear regression model between the two variables that reveals that if all factors affecting vitamin D status are held constant, the percentage body fat explains 28.2% of the variability in the vitamin D status. Conclusion: In conclusion, there is a statistically significant connotation between body fat and vitamin D status amongst female students. Further investigation is in need to tackle this health issue.

Abstract: Many researchers have reported that vitamin D can affect brain development as well as brain function. The prevalence of vitamin D deficiency in the Saudi population is 81% and it is more among women than among men. Though many studies have been done to find out the factors influencing the academic performance of Health sciences students, there is not adequate evidence regarding the influence of vitamin D level on academic performance. Therefore, this study aims to find out the association if any, between the vitamin D level and academic performance of health sciences students. After obtaining the ethical committee approval, the data was collected from 86 female medical students, 70 female applied medical sciences students and 57 nursing students of Northern Border University. The detailed questionnaire contained the aim of the study, demographic characteristics and academic performance predictors such as self-efficacy, academic motivation, academic engagement and social engagement. The vitamin D levels were measured by an enzyme-linked immunosorbent assay (ELISA) machine (BioTek) which is available in the local hospital. The multiple linear regression analysis was used to find out the association between vitamin D levels and academic performance. This study showed that vitamin D level had a significant association with the overall performance of the students as well as their self-efficacy. Since there is a lot of stress among health sciences students due to subject overload and inadequacy of time, the health aspects are often overlooked. This study emphasizes the importance of early screening of vitamin D levels and early intervention in those with low vitamin D levels for better academic performance. There is very little awareness of the impact of vitamin D deficiency on academic motivation, academic engagement, social engagement and self-efficacy among medical and health sciences students. This study can increase awareness. There are very few studies done to find out the association between Vitamin D level and academic performance. This study is unique as it has highlighted the association between vitamin D level and grade point average (GPA) and also the association between vitamin D level and academic predictors such as self-efficacy, academic motivation, academic engagement and social engagement.
