Table 2 Areas under the ROC curve of VFA, WC and BMI to identify the presence of the metabolic risk factors other than WC

From: The cutoff values of visceral fat area and waist circumference for identifying subjects at risk for metabolic syndrome in elderly Korean: Ansan Geriatric (AGE) cohort study

  1. VFA, visceral fat area; WC, waist circumference; BMI, body mass index
  2. aHigh blood pressure was diagnosed if systolic blood pressure was ≥130 mmHg, diastolic blood pressure ≥85 mmHg, or the subjects was receiving antihypertensive medications.
  3. bHypertriglyceridemia was diagnosed if triglycerides was ≥ 150 mg/dl in men and women.
  4. cLow HDL cholesterol was diagnosed if HDL cholesterol was < 40 mg/dl in men and < 50 mg/dl in women.
