 Metabolic syndrome MS, comprised of central obesity, glucose intolerance, hyperinsulinemia, low HDL-cholesterol HDL-C, high triglyceride TG and hypertension, results in markedly increased risk for cardiovascular disease in the general population. The National Cholesterol Education Program Adult Treatment Panel III NCEP ATP III report recommended the use of five variables for the diagnosis of the MS including waist circumference WC, serum TG concentration, serum HDL-C concentration, blood pressure and fasting glucose concentration. A waist circumference of 80 cm in women and 90 cm in men would better identify those with the MS in Asian populations. However, the studies of modified asian criteria of metabolic syndrome in hemodialysis HD patients are scarce.
