SD = standard deviation.
∗IQR = interquartile range.
†Clinical cut points: CRP > 3 mg/dL; glucose ≥ 100 mg/dL; triglycerides ≥ 150 mg/dL; HDL <40 (men) or <50 (women); waist circumference >102 cm (men) or >88 (women); BMI ≥ 30 kg/m²; systolic blood pressure ≥ 140 mm Hg; and diastolic blood pressure ≥ 90 mm Hg.
‡Meets 3/5 ATP III criteria for metabolic syndrome (source: [30] ). Five criteria include (1) glucose ≥ 100 mg/dL; (2) triglycerides ≥ 150 mg/dL; (3) HDL < 40 (men) or <50 (women); (4) waist circumference > 102 cm (men) or >88 cm (women); and (5) blood pressure ≥ 135/85 mm Hg.
