Background
Diabetes mellitus is known to be an international health concern with micronutrient deficiencies, especially an imbalance of vitamin D and iron levels, being identified as possible risk factors for increased development of diabetes. This report proposes research that examines correlations between vitamin D, hemoglobin, ferritin, and diabetes for the Saudi Arabian population.Objective
The aim is to evaluate the association between serum vitamin D, ferritin, and hemoglobin levels and glycemic status, as measured by fasting blood glucose (FBS) and glycated hemoglobin (HbA1c), among adult patients attending a tertiary care hospital in Al-Ahsa, Saudi Arabia.Methods
This Cross-sectional study was carried out in King Faisal Polyclinics in Al-Ahsa, Kingdom of Saudi Arabia between Aug 2024 and Jan 2025 on 249 participants (proportional sampling for both genders). The variables were measured for Fasting Blood Sugar (FBS) levels, HbA1c%, Hemoglobin (Hb), Ferritin level, and Vitamin D level. All analyses were done in SPSS software version 26. Correlation analysis between variables were done by using One-Way ANOVA and Pearson's Chi-Square Tests. Significance level was kept at p<0.05.Results
The mean age (in years) was 47.4 ± 13.8 years. For HbA1c, the value was 18.9% for diabetics, 21.3% for pre-diabetics, and 40.6% for non-diabetics. Vitamin D deficiency (<20 ng/mL) was observed in 11.2% of the subjects. Ferritin had a significant association with HbA1c and FBS (p <0.05). For females, hemoglobin approached significance in the context of FBS. Vitamin D.Conclusion
The results indicate the importance of ferritin and hemoglobin levels for glucose regulation as well as the uncertain and potentially insignificant role of the level of vitamin D. Larger follow-up studies will have the potential to clarify the importance of micronutrients for the prevalence of diabetes.
