Background: Menstrual disturbance in polycystic ovary syndrome (PCOS) may be a predictor for grade of insulin resistance (IR). Objectives: To observe relation of variants of menstrual disturbances with IR and metabolic syndrome in PCOS. Methods: This cross sectional study included 100 PCOS women [age: 22.34±4.40 years; body mass index (BMI) 25.96±4.87 kg/ m2; mean±SD], diagnosed by Rotterdam criterion and 60 age matched controls (age: 22.98±4.64 years, BMI 21.15±3.91 kg/ m2; mean±SD). The subgroups were classified according to menstrual cycle length as: gr-I (<26 days; polymenorrhoeic), gr-II (26–34 days; eumenorrhoeic), gr-III (35–45days; mild oligomenorrhoeic), gr-IV (6 weeks to three months; severe oligomenorrhoeic) and gr-V (>3 months; amenorrhoeic). Insulin and glucose were measured to determine glycemic status and IR. Results: Oligomenorrhoea was more among the age group of 16–30 (~60%), whereas one third of age group of 31–35 was amenorrhoeic. BMI and waist circumference (WC) were significantly higher in all subgroups of PCOS than control (gr-I: 30±4.49, gr-II: 24.75±3.85, gr-III: 26.08±5.37, gr-IV: 26.02±4.68, gr-V: 83.58±14.51, control: 21.14±3.90 kg/m2; p<0.001; WC: 92.00±0.00, 81.28±9.75, 85.56±11.57, 81.22±10.61, 83.58±14.51 and 72.02±7.44, respectively; p<0.001). PCOS
and control also showed statistically significant differences for IR (100% vs. 27.3% vs. 51.4% vs. 53.8% vs. 61.5% vs. 3.3%, respectively; p<0.001) and metabolic syndrome (50% vs. 11.1% vs. 31.3% vs. 22.25% vs. 41.7% vs. 3.3%; p=0.002) and prediabetes (50% vs. 22.25% vs. 29% vs. 27.8% vs. 33.3% vs. 1.6%; p=0.002). Each subgroup had statistically significant values of fasting glucose, 2-h glucose, fasting insulin, FG/FI, HOMA-IR, total cholesterol, triglycerides, HDL, LDL than that of control (p<0.05 for all). Multiple regression analysis revealed that cycle length of menstruation (p=0.014), WC (p=0.050) and Ferriman-Gallwey score (p=0.0108) were independent predictors of homeostatic model assessment (HOMA-IR) in PCOS. Conclusions: Prevalence of IR and metabolic abnormalities are higher in PCOS. Subgroups with amenorrhoea and oligoamenorrhoea have adverse metabolic profile and IR.
