ABSTRACT

Background: Systemic mineral and bone metabolism disorders are frequently observed in patients with hemodialysis (HD). Patients undergoing hemodialysis have vitamin D deficiency; which can affect up to 90% of HD patients, and this is linked to higher risks, as well as increased all-cause mortality. Objectives: To examine the association between dietary intake of vitamin D and (vitamin D deficiency, bone mineral biomarker) in hemodialysis patients. Methods: From January to May 2024, 100 hemodialysis patients at Dialysis Centre in Medical City, Baghdad-Iraq participated in a cross-sectional research. A questionnaire filled out by the researcher with a direct interview gathered demographic, clinical, anthropometric, laboratory, and vitamin D consumption data. Arab Board for Health Specialisations committee approved ethics. All data were obtained using Excel for Windows and analysed using SPSS 26. A p-value under 0.05 was significant. Results: The study reports that the mean age and BMI of patients were 53.38±13.69 years and 27.44±4.86 kg/m^2 respectively, with a male to female ratio of 1.2:1. Among HD patients, 79% had inadequate Vitamin D3 levels, with eggs and fats being the strongest predictors of adequate levels at specific consumption thresholds. Milk, yogurt, and fish also significantly predicted adequate Vitamin D levels at defined weekly servings. Conclusions: S. Vit D3 was Adequate among 21.0% of patients and Inadequate among 79.0%. Low levels of Hb and dietary intake of milk, yogurt, cheese, egg, fish, grains, fat, and legumes were determinants of inadequate S. Vit D3 level among HD patients. Dietary intake of egg, fat, milk, yogurt, and fish can be used as predictors for adequate vitamin D level in HD patients.
