†Hypertriglyceridaemia was defined as a level above the 95th percentile for age and sex; low HDL-cholesterol means a level below the 5th percentile for age and sex; hypertension means a systolic or diastolic blood pressure above the 95th percentile for age, sex and height; hypercholesterolaemia means a level ⩾200 mg/dl; hyperglycaemia means a level of ⩾100 mg/dl; and high LDL-cholesterol means a level ⩾130 mg/dl.
‡The metabolic syndrome was diagnosed in patients who met three or more of the following criteria for age and sex: a BMI above the 97th percentile (z-score, 2.0 or more), a triglyceride level above the 95th percentile, an HDL-cholesterol level below the 5th percentile, systolic or diastolic blood pressure above the 95th percentile, and a fasting glucose value of at least 100 mg/dl as proposed.29 30
