Table 4 Frequency of metabolic syndrome components in patients with metabolic syndrome according to IDF and NHLBI/AHA criteria

From: Prevalence of the metabolic syndrome in patients with carotid disease according to NHLBI/AHA and IDF criteria: a cross-sectional study

Metabolic syndrome component Without MetS MetS by both criteria MetS by IDF only MetS by NHLBI/ AHA only pvaluea

  Number (%) Number (%) Number (%) Number (%)

  1. a For comparison between IDF criteria only and NHLBI/AHA criteria only; p values were not calculated for waist circumference because of the basic differences between the two metabolic syndrome definitions.
  2. b > 94 cm in men and > 80 cm in women, by IDF criteria; > 102 cm in men and > 88 cm in women, by NHLBI/AHA criteria.
  3. c ≥ 1.7 mmol/L or specific medication
  4. d ≥ 5.6 mmol/L or history of diabetes mellitus or taking antidiabetic medication.
  5. e Systolic blood pressure ≥ 130 mmHg or diastolic blood pressure ≥ 85 mmHg or antihypertensive therapy.
  6. f High density lipoprotein cholesterol < 1.03 mmol/L in men, and < 1.29 mmol/L in women or specific medication.
