Background: Obesity and type 2 diabetes have both rapidly raised during the last periods and are ongoing to increase at a disturbing rate universal. Several clinical and epidemiological researches demonstrated a reverse association between circulating vitamin D levels, central adiposity and the progress of insulin resistance and diabetes. Objective: The target of this work was to elucidate the complex role of vitamin D and the clinical implications of diabetes on metabolic defects related with obesity. Subjects and Methods: This study encompassed 90 diabetic patients (45 obese and 45 non obese) who were attending the National Diabetic Center/ Al-Mustansiriyah University during the period from June 2019 to January 2020; their age range was (35-60) years. All participant underwent clinical and biochemical examinations. Results: A substantial rise (p= 0.01) in waist/hip ratio, body mass index, fasting serum glucose, total cholesterol, triacylglycerol, and low density lipoprotein cholesterol in obese diabetic patients as paralleled to non-obese group. Moreover, there was an elevation in glycated hemoglobin, serum insulin, and homeostasis model assessment for insulin resistance in obese group, but it was not significant. A substantial decrease (p= 0.01) in serum high density lipoprotein cholesterol and vitamin D3 were detected in obese diabetic patients as paralleled to non-obese group.       Also, obese diabetic patients had the higher percent (61%) of D3 deficiency as paralleled to non-obese patients. Conclusions: In the present study, it is found that there is significant increase in blood sugar in the individuals with decreased vitamin D levels, which was related with insulin resistance, decreased β-cell function, and obesity.

1. One-day-old chicks were depleted of vitamin D. At 3 weeks their right tibiae, and those of a control group given vitamin D3, were fractured and pinned. After fracture the controls were kept on vitamin D3. Another group was left vitamin D-deficient. The remaining depleted chicks, divided into four groups, were given vitamin D3, 24,25-dihydroxyvitamin D3 [24,25(OH)2D3], 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] or a combination of 24,25(OH)2D3 and 1,25(OH)2D3. 2. The callus obtained after 9 and 14 days was subjected to torsional stress. The callus of chicks given vitamin D continuously showed the greatest resistance, whereas that of vitamin D-deficient chicks showed the smallest resistance. Repletion with either vitamin D3 or its metabolites increased the strength of the callus. Repletion with the combination of 24,25(OH)2D3 and 1,25(OH)2D3 produced the most marked results, in that the callus was even stronger than that of chicks replete with vitamin D3. 3. It is concluded that 24,25(OH)2D3 is essential for bone formation in addition to the known active vitamin D metabolite 1,25(OH)2D3, and the possible clinical implications of these findings are discussed.
