Prevalence of MONW and its components according to serum ferritin levels in KNHANES, 2008 to 2010 in male (a) and female (b), respectively. MONW was defined by the presence of ≥2 of the following criteria: systolic blood pressure ≥130 mm Hg, diastolic blood pressure ≥85 mm Hg, or use of antihypertensive medication; triglyceride level ≥150 mg/dL or use of lipid-lowering medication; fasting plasma glucose level ≥100 mg/dL or use of an oral hypoglycemic agent or insulin; HDL cholesterol level <40 mg/dL in men and <50 mg/dL in women or use of medication for reduced HDL cholesterol level; and HOMA-IR greater than the 90th percentile in the nondiabetic general Korean population in KNHANES. The data are presented as a percentage (standard error), and P values were obtained by the χ² test. HDL = high-density lipoprotein; HOMA-IR = homeostasis model assessment of insulin resistance; MONW = metabolically obese normal weight.
