Abstract

Obesity is a risk factor for type 2 diabetes and low serum 25(OH) D. The relationship between vitamin D status and BMI in T2DM Jordanian patients was studied. The study was a matched case-control study on (55) diabetic cases and (55) controls. Serum levels of fasting plasma glucose, insulin, calcium, glycosylated haemoglobin, vitamin D and parathyroid hormone were determined, while body mass index, the homeostasis model assessment- insulin resistance, the homeostasis model assessment-�� secretion and the quantitative insulin sensitivity check index were calculated. Mean serum vitamin D levels for diabetic patients and nondiabetic subjects were deficient status adjusted for age and sex. Mean BMI was in the overweight level 25â�� 29.9 Kg/m2 for both groups. There were significant differences (p<0.05) in HOMAâ��IR between groups (6.1�±1.2 vs. 2.7�±1.2, respectively) and both groups had higher than normal serum insulin and insulin indices. 62.5% of the overweight and obese diabetic patients in this study were either deficient or insufficient in vitamin D compared to 37.5% of them were sufficient. For the whole sample, significant correlations, although not high, were obtained between serum vitamin D and Ca (r = 0.2, P<0.05) and PTH (r = -0.4, P<0.05). For the diabetic subjects, the significant correlation was only with PTH (r = -0.4, P<0.05). Whereas, for the non-diabetic subjects, serum insulin (r = 0.4, P<0.05), HOMA-IR (r = 0.4, P<0.05), HOMA-�� (r = 0.4, P<0.05), QUICKI (r = - 0.3, P<0.05) and PTH (r= - 0.4, P<0.05) were significantly correlated with serum vitamin D. Serum levels of vitamin D and calcium have significant inverse relationship with BMI in diabetic patients. Vitamin D deficiency seems to be a problem in different parts of Jordan. Incidence of vitamin D deficiency is high in diabetic and non-diabetic groups
