besity 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-ß 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 25–
29.9 Kg/m2 for both groups. There were significant differences (p<0.05)
in HOMA–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-ß (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.
