Abstract

OBJECTIVES: To evaluate i) the correlation between vitamin D (vit. D) serum concentrations and metabolic syndrome (MetS); ii) the efficacy of 6 months supplementation therapy with vit. D.

METHOD: 200 patients were enrolled. Blood analyses and anthropometric measurements were carried out. Patients with hypovitaminosis D received an oral supplement therapy.

RESULTS: 81% of the sample shows vit. D levels < 30 ng/mL. Rate of MetS was significantly higher in vit. D deficiency group than in vit D insufficiency (p = 0.009) and sufficiency (p = 0.002) groups. Vit. D shows a significant negative correlation with both waist circumference (WC) (ρ - 0.202 p = 0.004) and glycaemia values (FBG) (ρ -0.185 p = 0.009). After the supplementation therapy in a group of 60 subjects a significant increase in vit. D levels (p = 0.001) and a significant reduction in WC values (p = 0.001) were observed.

CONCLUSIONS: MetS, WC and FBG appeared to be associated vit. D status and it is well-known that central obesity, with the inflammatory alterations thereto correlated that determine insulin resistance, can be considered the "primum movens" for the development of MetS.
