Association of Serum Vitamin D Concentrations with Dietary Intake in a Sample of Jordanian Students

Abstract

Abstract Background Optimal levels of vitamin D are vital for preventive health. However, vitamin D deficiency is still among the most common issues around the world at every age. Consequently, the current study is intended to investigate serum 25(OH)D levels in a sample of Jordanian students. The main aim is to assess the relationship between the estimated diatary intake of vitamin D and the serum of vitamin D, and to conduct biochemicl tests focused on the Jordanian context. Method A cross-sectional design has been adopted, 171 students aged between 18 and 25 years. and data collection and analyses were composed of several steps. Results The findings of this study revealed that the BMI showed a normal range in the majority of the participants (59.6%). The outcomes of biochemical testing were satisfactory as the levels fell within normal ranges, as mean total hemoglobin, packed cell volume, fasting blood glucose, total cholesterol, triglycerides, HDL-cholesterol, cholesterol/HDL ratio, LDL,and total preotein were 142.9 (g/L), 0.43 (l/l), 4.75 (mmol/L), 4.07 (mmol/L), 1.1 9(mmo/L),1.39 (mmol/L), 3.025, 2.17 (mmol/L), and 77.6 (g/L), respectively. Overall, from the results, it was found that the average dietary intake of students in the current sample was considered good. However, the intakes of folate, zinc, and vitamin B6 were bellow the recomendded intake. Conclusions Therefore, it is concluded that there is a need for further maintenance of optimal levels of vitamin D concentrations in their dietary intake to attain more suitable serum levels and overall health outcomes.
