چکیده
AIM To evaluate the association of vitamin D (VD) deficiency with gonadotropins and sex hormone in obese and non-obese women with polycystic ovary syndrome (PCOS). METHODS Of the total of 140 women, thirty obese and thirty nonobese, aged 20-40 years, were included in the study. Inclusion criteria were the women with normal level of thyroid-stimulating hormone (TSH), prolactin (PRL), parathyroid hormone (PTH), and calcium, and those who had not received any medication or VD supplementation within the last 6 months. Serum 25- hydroxyvitamin D (25(OH)D), C-reactive protein (CRP), lipid profile, fasting serum glucose, basal insulin, homeostasis model analysis of insulin resistance (HOMA-IR) index, follicle-stimulating hormone (FSH), luteinizing hormone (LH), oestrogen, total testosterone, dehidroepiandrostendion-sulphat (DHEA-S), androstendione, and sex hormone binding globulin (SHBG) were determined at follicular phase. RESULTS Body mass index (BMI), weight, waist, lipids, and CRP were significantly higher in obese than in non-obese PCOS women (p=0.000). Meanwhile, insulin and HOMA-IR were also higher in the obese PCOS (p less than 0.000), and so was the fasting glucose (p=0.004). Furthermore, obese PCOS showed significantly higher level of LH (p=0.012), but lower level of progesterone (p=0.001) and androstendione (p=0.006) than in non-obese PCOS. In total 68% of PCOS women had VD deficiency but without significant difference among groups according to BMI. There was no association of VD deficiency with gonadotropins and sex hormones except SHBG. CONCLUSION Insulin resistance was a better independent risk factor for the presence of vitamin D deficiency than SHBG. The insulin resistance and vitamin D deficiency significantly predicted the obesity risk in PCOS women.
