Abstract

Objective. To investigate the possible association of calcium and vitamin D deficiency with hypoadiponectinemia in women with PCOS. Subjects and Methods. In this case-control study, 103 PCOS cases and 103 controls included. The concentrations of calcium, 25-OH-vitamin D (25OHD), adiponectin, insulin, glucose, total cholesterol, HDL-cholesterol, triglyceride (TG), and androgens were measured in fasting blood samples. Results. Adiponectin (8.4±2.7 ng/mL versus 13.6±5 ng/mL in control group, 𝑃0.00), calcium (2±0.1 mmol/L versus 2.55±0.17 mmol/L in controls, 𝑃0.00), and 25-OH-Vit D (30±2.99 nmol/L versus 43.7±5.2 nmol/L in control group, 𝑃0.00) levels were decreased in women with PCOS. Subjects with PCOS had higher concentrations of TG (1.4±0.77 mmol/L versus 1.18±0.75 mmol/L in control group, 𝑃0.019) and dehydroepiandrosterone sulfate (DHEA-S) (10.7±11 mmol/L versus 9.7±10.4, 𝑃0.02 in control group). There were significant correlations between adiponectin concentrations with calcium (𝑟0.78, 𝑃0.00) and 25OHD levels (𝑟0.82, 𝑃0.00). The association of hypoadiponectinemia and PCOS was not significant considering 25OHD as a confounding factor. Conclusion. The present findings indicate that the association of hypoadiponectinemia with PCOS is dependent on vitamin D. A possible beneficiary effect of vitamin D on the metabolic parameters in PCOS may be suggested.
