HDL-C high-density lipoprotein cholesterol (mg/dL), TG triglyceride (mg/dL), FBG fasting blood glucose (mg/dL), BP blood pressure (mmHg)
Criterion for diagnosing Components of the metabolic syndrome was obtained based on Adult Treatment Panel III: TG ≥ 110 mg/dL, HDL-C ≤ 40 mg/dL, WHR greater than 0.5, FBG ≥ 100 mg/dL, and SBP or DBP ≥ 90th percentile for age, sex and height
^aAdjusted for age, sex, living area, SES, PA, ST, healthy and unhealthy eating behaviors, family history of chronic diseases and parental BMI
