Status of a lipid accumulation product, triglycerides/glucose index and visceral adiposity index on cardiometabolic risk factors in young polycystic ovary syndrome patients

Abstract

Objective: To determine whether the triglycerides/glucose index (TyG-index), lipid accumulation product (LAP), and visceral adiposity index (VAI) would differ in young polycystic ovary syndrome (PCOS) patients when compared to the non-PCOS group, and to investigate the relationship between these markers and cardiovascular disease (CVD) risk in PCOS patients. Materials and methods: One hundred and ninety two women with PCOS, and 148 age and body mass index (BMI) matched healthy women without PCOS were enrolled. Levels of serum androgens, sex hormones, lipids, fasting glucose, fasting insulin, and N-terminal pro-brain natriuretic peptide (Nt-probnp) were determined. The 75 g oral glucose tolerance test was performed. The Homeostatic Model Assessment-Insulin Resistance Index (HOMA–IR) and Matsuda insulin sensitivity index were calculated. Levels of TyG-index, LAP, and VAI were determined. Results: TyG, LAP, and VAI were significantly higher in PCOS patients than in the control group (P = 0.001 vs. P = 0.001 vs. P = 0.001, resp.). HOMA-IR was significantly higher in PCOS patients and Matsuda ISI was significantly lower in PCOS patients (P = 0.001 vs. P = 0.001, resp.). Levels of Nt-probnp were significantly higher in PCOS patients (P = 0.001). Serum total testosterone and androstenedione levels had significant correlations with TyG, LAP, and VAI. Nt-probnp was significantly correlated with TyG, LAP, and VAI. LDL was positively correlated and HDL was negatively correlated with TyG-index, LAP, and VAI. Conclusion: PCOS patients have increased values of TyG-index, LAP, and VAI. TyG index, LAP, and VAI may indicate an increased risk of CVD and hyperandrogenism in PCOS patients.
