Comparison of vitamin D levels in obese and non obese patients with polycystic ovarian syndrome in a South Indian population

Polycystic ovary syndrome (PCOS) is the most common metabolic abnormality occurring in young women of reproductive age. Low vitamin D levels were found to be associated with the development of obesity and insulin resistance in young women with PCOS. The study was conducted as a prospective observational study involving 121 women with PCOS. The diagnosis of PCOS cases were based on the revised Rotterdam consensus criteria. Vitamin D levels were compared in the obese and non obese PCOS groups and also with the controls. In the PCOS group, sixty subjects were obese with BMI of ?25 kg/m2 and forty seven subjects were found to be non obese. In the control group, sixteen subjects were obese and sixty five subjects were non obese. The mean vitamin D level in the PCOS group was 15.45±7.88 ng/ml and in the control group was 12.83±5.76ng/ml. The mean vitamin D levels in the obese and non obese group with PCOS were 16.11±8.9ng/ml and 14.61±6.1ng/ml respectively. Majority of the patients and controls had vitamin D deficiency and there was no difference in the vitamin D levels in PCOS group and controls as well as obese and non obese groups.
