Background: Polycystic ovary syndrome (PCOS) is a heterogeneous disorder of uncertain etiology. Objectives: To see the phenotypes and frequencies of insulin resistance and metabolic syndrome in PCOS. Materials & Methods: This study included 100 PCOS women (age, mean±SD: 23±5 years; body mass index, BMI: 27.6±4.6 kg/m2), recruited on the basis of Rotterdam criteria and 25 healthy controls (age, mean±SD: 24±5 years; BMI: 24.2±4.9 kg/m2). Hormonal analysis was done using chemiluminescent immunoassay. PCOS phenotypes were defined as: A (oligoanovulation + hyperandrogenism + PCO), B (oligo-anovulation + hyperandrogenism), C (hyperandrogenism + PCO) and D (oligo-anovulation + PCO). Results: Frequency of PCOS phenotypes were highest for A (57%), followed by D (16%), B (14%) and C (13%). BMI, waist circumference (WC), waist/hip ratio and Ferriman-Gallwey (FG) score showed statistically significant difference when control group was included, but not among the PCOS phenotypes. Highest value of fasting insulin was observed in A followed by D, B and C, and all were higher than control. Frequencies for pre-diabetes, insulin resistance and metabolic syndrome were significantly higher in PCOS. Phenotypes (A vs. B vs. C vs. D) also showed difference for total testosterone (85.82±28.44
vs. 82.84±22.7 vs. 76.09±27.5 vs. 34.35±5.17 ng/dl; p<0.001); testosterone was higher in A, B, C but all had significantly higher level than D (p<0.001 for all). Homeostatic model assessment (HOMA-IR) significantly correlated with BMI, fasting blood glucose, 2-h glucose, total cholesterol and triglyceride in PCOS. Logistic regression showed that age > 25 years, WC > 80 cm, BMI > 25 kg/m2, and FG score were risk factors for metabolic syndrome. Using IR as a dependent variable, A and C was associated with 17-fold, 13-fold and 11-fold increased risk of developing insulin resistance, while phenotype D with 9-fold compared to control. Conclusions: Phenotype A is the most common, followed by others, while A and B have adverse metabolic outcome.
