The aim of this article is to study the possible relation of serum vitamin D concentrations to body mass index (BMI), visceral fat thickness (VFT), insulin resistance (IR), inflammation (serum monocyte chemoattractant protein-1 - MCP-1) and thyroid parameters in obese patients. A total of 158 non-diabetic, obese patients aged 19-68 without a history of thyroid pathology were recruited. Biochemical markers, insulin, 25-OH vitamin D, thyroid parameters (TSH, FT3, FT4, TPO antibodies, TG antibodies) and VFT were measured.
