*p<0.05 and **p<0.001 compared to urban participants; Dyslipidemia was diagnosed using NCEP guidelines – hypercholesterolemia: Total cholesterol (TC) ≥200 mg/dl; hypertriglyceridemia: triglycerides ≥150 mg/dl; low HDL cholesterol: HDL-C <40 (males) and <50 mg/dl (females); high LDL cholesterol: LDL-C ≥130 mg/dl; High total cholesterol: HDL-C ratio ≥4.5; Isolated hypercholesterolemia: TC ≥200 mg/dl and triglycerides <150 mg/dl; Isolated hypertriglyceridemia: serum triglycerides ≥150 mg/dl and TC <200 mg/dl; Isolated low HDL-C: HDL-C ≤40 mg/dl (male) and ≤50 mg/dl (female) without hypertriglyceridemia or hypercholesterolemia.
