Introduction: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting women of reproductive age. It is associated with insulin resistance (IR) and high cardiovascular risk (CVR). According to the Rotterdam consensus, four PCOS phenotypes could be established: three with clinical and/or biochemical hyperandrogenism (HA), and one non-hyperandrogenic (NHA). It is necessary to identify which of these patients are at risk of metabolic disturbances and CVR. Two indexes: lipid accumulation product (LAP) and visceral adiposity index (VAI) have been suggested as reliable markers of IR and CVR in PCOS. Objective: The present study aims to assess the reliability of LAP and VAI as IR markers in a young local population of PCOS patients. Their association with CVR parameters is also evaluated. Methodology: LAP and VAI were calculated in 130 PCOS patients. The PCOS patients were divided in two groups as HA and NHA, taking into account the signs of hyperandrogenism (clinical or biochemical). An evaluation was also made of the metabolic and anthropometric characteristics of the population and their association with CVR and IR. Results: Both LAP and VAI showed to be effective markers to asses CVR and IR in these PCOS women (cutoff values: LAP: 14.02 (sensitivity: 93.94% specificity: 93.22%) VAI: 2.17 (sensitivity: 87.88% specificity: 91.38%). There was a positive correlation of both markers with abdominal circumference and triglycerides (TG), and negative with HDL-cholesterol. The risk of IR and metabolic disturbances was similar in both phenotypes (NHA versus HA). Conclusion: Our data show that both LAP and VAI are representative markers for assessing IR and associated CVR in PCOS patients. These results also suggest that the NHA phenotype in the population studied shows the same risk of metabolic disturbances and cardiovascular disease when compared to HA phenotypes.
