Relationship of vitamin D level with HOMA IR and LH in PCOS patients

Background: the most prevalent endocrine disorder in young women is polycystic ovary syndrome (PCOS). In many patients, vitamin D insufficiency aggravates the condition. Early diagnosis of insulin resistance and vitamin D insufficiency will simplify management and reduce morbidity in the future. This study analyzes the relationship between vitamin D levels and HOMA IR and LH in PCOS patients and compares the levels of LH and HOMA IR between obese and non-obese PCOS. Method: This study used a cross-sectional study on 48 women of reproductive age who were diagnosed with PCOS according to the Rotterdam criteria and who met the inclusion and exclusion criteria. Subjects were taken by consecutive sampling, measured levels of vitamin D, HOMA IR, and LH, then correlated and compared between obese and non-obese. Results: 48 samples were included in the study conducted within 3 months. A significant relationship was found between vitamin D and HOMA IR levels in PCOS patients with a p-value of 0.000. There was a significant relationship between vitamin D and LH levels in PCOS patients with a p-value of 0.000. There were significant differences in HOMA IR and LH levels in obese and non-obese PCOS patients, with higher HOMA IR in obese patients with a p-value of 0.001 and higher LH levels in non-obese PCOS patients with a p-value of 0.045. Conclusion: there was a significant relationship between vitamin D levels and HOMA IR and LH in PCOS patients and a significant difference in HOMA IR and LH in obese and non-obese PCOS patients.
