  • Data are mean ± SD or n (%). BMI is weight in kilograms divided by the square of height in meters. The waist-to-height ratio is waist circumference divided by height. Hypertension was defined as a systolic blood pressure of ≥140 mmHg, a diastolic blood pressure of ≥90 mmHg, or the use of antihypertensive therapy. Dyslipidemia was defined as an LDL cholesterol level >160 mg/dL (4.1 mmol/L), an HDL cholesterol level of ≤40 mg/dL (1.0 mmol/L) in men or ≤50 mg/dL (1.3 mmol/L) in women, or the use of lipid-lowering therapy.
