aHigh systolic/diastolic blood pressure (BP) was defined as ≥95th percentile for sex, age, and height from the National Heart, Lung, and Blood Institute’s recommended cut points. bDyslipidemia was defined according to the recent recommendations of the American Heart Association, ie, total cholesterol (TC) ≥200 mg/dL (5.2 mmol/L) and/or triglyceride (TG) ≥200 mg/dL (2.26 mmol/L) and/or low-density lipoprotein cholesterol (LDL-C) ≥130 mg/dL (3.38 mmol/L) and/or high-density lipoprotein cholesterol (HDL-C) <40 mg/dL (1.04 mmol/L). cSignificant difference between the 3 surveys in 15–19 year age group. dSignificant difference between the 3 surveys in 10–14 year age group.
