STATUS OF VITAMIN D AMONG TURKISH ADULTS WITH TYPE 2 DIABETES MELLITUS IN PRIMARY HEALTH CARE

Aims: The aim of our study was to investigate the prevalence and correlates of 25-hydroxy vitamin D (25(OH)D) deficiency and the relationship between 25(OH)D and the type 2 diabetes mellitus (T2DM) in primary health care. Materials and methods: One hundred and thirty Jour Turkish adults with T2DM from the Family. Medicine outpatient clinic and 134 non-diabetic, healthy controls were included in the study. We measured serum 25(OH)D, calcium; low density. lipoprotein (LDL), insulin, parathormone (PTH) and blood fasting glucose and compared the results between the T2DM group and matched healthy control subjects. Results: Both the T2DM and healthy groups had vitamin D deficiency. The mean age for those with T2DM was 58.00 +/- 12.03 years versus 46.76 +/- 15.70 years among the controls. The mean levels of 25(OH)D were significantly lower in the T2DM adults than in the controls (11.85 +/- 8.51 ng/ml versus 15.33 +/- 17.42 ng/m1). In the T2DM adults, 35.8% were mildly (10-20 ng/ml), 35.8% were moderately (5-10 ng/ml), and 17.2% were severely (<5 ng/ml) vitamin D deficient as compared with 26.1% (mildly), 41.8% (moderately); and 11.9% (severely) in the control group. Overall, 88.8% of the T2DM patients and 79.9% of the healthy controls were vitamin D deficient. Conclusion: This study demonstrated prevalent vitamin D deficiency in patients with T2DM and normal subjects. The population in our study was generally deficierit in 25(OH)D indicating a greater need for vitamin D supplementation.
