The Correlation Between the Vitamin D Level and Glycemic Control Status Among Diabetic Patients - A Clinical Observational Study

Abstract

Background: Vitamin D deficiency is widespread and coexisted with diabetes. However, the relation between Vitamin D level and glycemic control is not yet fully understood. This study examines the correlation between vitamin D level and glycemia indicators and diabetic microvascular complications.
Methods: The study is a cross-sectional study, had been done at the outpatient department in Najran university hospital, Saudi Arabia from May 2019 to February 2020. 220 patients recruited by simple random sampling.
Results: 60% of diabetes (n-130) had been using oral anti-glycemic medications, though most of them had uncontrolled glycemic status and had got microvascular complications. It is notable that among diabetes having a low vitamin D level; 55.5% had high FBS, 45.6% had high RBS and 65% had high HBA1C. Besides,17% have retinopathy, 16.6% have nephropathy, 26.2% have peripheral neuropathy and 1.9% have a diabetic foot.
Conclusion: The clinical and laboratory assessments are essential to control the glycemic state in diabetes. The study noted that an inverse relationship between the level of vitamin D with blood sugar levels and diabetic microvascular complications. To assure the feasibility of the prediction of vitamin D level in assessing the progress of diabetes further studies are needed.
