Background: Studies have identified that the deficiency of vitamin D is strongly connected with diabetes mellitus type 1. Vitamin D has the capability to control increased blood glucose level. Purpose: The study appraises the association among vitamin D deficiency, type 1 diabetes mellitus, and glycated hemoglobin among children. Methods: Around, 226 diabetic children were selected for this retrospective study from outpatient department of King Abdul Aziz University Hospital. Majority of the participants were female individuals, with the rate of 61.1% and were divided into three categories, based upon the rate of vitamin D deficiency. Every participant of the study was taking intensive insulin therapy. Results: The findings of the study have shown that 77% of the diabetic patients had reduced level of vitamin D in total. The study identified, from the evaluation between HbA1c control and vitamin D status, that 66% of the diabetic and vitamin D deficient participants were poorly controlled (HbA1c>9%). Conclusion: Vitamin D deficiency among the patients of diabetes mellitus type 1 was extremely high and was closely related with glycemic control. Additionally, the findings of the study have demonstrated therapeutic implications that the supplements of vitamin D have the potential to manage glucose level.
