Abstract
Background: Vitamin D is a fat-soluble vitamin Known as the sunshine vitamin; vitamin D is produced by the body in response to skin being exposed to sunlight. It is also occurs naturally in a few foods -- including some fish, fish liver oils, and egg yolks. Hypo vitamin D has recently been considered a responsible factor in the onset and progression of diabetes mellitus (DM) and chronic kidney disease (CKD). Vitamin D is involved in different mechanisms related to the development of type 2 diabetes, including beta cell activity and insulin sensitivity. Vitamin D levels are lower in people with obesity and type 2 diabetes, but it is unknown if there is a causal relationship between these events. Objective: To evaluate the vitamin D status and its effect on glycemic control in patients with type2 diabetesmellitus. Patients and Methods: A cross sectional study done on 150 type 2 diabetic patients from outpatient department of the Al-Amiriyah general hospital in Al-Anbar, western Iraq from Aprilto September 2019 were selected as case group and 150 healthy subjects matched regarding sex and age (as control group) were evaluated. Results: The patients in the case group were 65 males (43.3%) and 85 females (56.7%), more than half of them were fall in the age group (41-50) and (51-60) years. The mean age was (50.7) years. While the peoples within control group were 67 males (44.7%) and 83 females (55.3%), also more than half of them were fall in the age group (41-50) and (51-60) year, and the mean age was (53.6) years. Low vitamin D level was observed in 82% of the diabetic patients, while it was observed in 58.7% of healthy individuals. The low vitamin D status was strongly associated with poor glycemic control (P<0.05). Conclusion: Vitamin D deficiency among the patients of diabetes mellitus type 2 was extremely high andwas closely related with glycemic control in our sample of diabetic patients. Association of low vitamin D status with poor glycemic control suggests a role of vitamin D in the control of type 2 diabetes mellitus and the importance of early detection of its deficiency and vitamin D supplementation.
