Visceral Adipose Tissue was Associated with Increased Risk of Insulin Resistance in Lean Polycystic Ovarian Syndrome, Independent with Retinol Binding Protein-4

Objective: To determine whether visceral adipose tissue or serum RBP-4 were related with the risk increment of insulin resistance in normal BMI PCOS patients. Methods: This was a cross-sectional study conducted in normal body mass index PCOS patients at Yasmin Clinic, RSCM, Jakarta from July 2014 until March 2015. Diagnosis of PCOS was established using Rotterrdam (2003) criteria. Insulin resistance was confirmed by using ratio of HOMA-IR >1.4. Results: Among 40 subjects, 20 subjects (50%) belong insulin resistance group. Serum RBP-4 level was higher in insulin resistance group (p=0.06). After ROC analysis was conducted, area under curve for of serum RBP-4 was 69.9% (CI 95% -3754.77 - (186.60-7696.14, p=0.061)). Cut-off level of serum RBP-4 was 23814.5 ng/mL yielded sensitivity and specificity to a level of 60% and 60%, respectively. After logistic regression were analyzed, visceral adipose tissue demonstrated substantial association with the risk increment of insulin resistance in normal BMI PCOS patients. Conclusions: Visceral adipose tissue demonstrated substantial association with the risk increment of insulin resistance in normal BMI PCOS patients, independent with serum RBP-4 levels.
