Model 1 did not adjust for any variables.

Model 2 further adjusted for history of mother and father regarding gout, education of mother and father, family income, and health history of parents in addition to all variables listed in the model.

*Overweight was defined as weight-for-BMI ≥ 85th percentile (≥1.035 Z score); Obesity was defined as weight-for-BMI ≥ 95th percentile (≥1.645 Z score); Sex-specific weight-for-BMI percentiles were based on WHO growth reference (World Health Organization, 2006).

^#Hypertension was defined in accordance with the blood pressure reference standards for Chinese children as systolic or diastolic BP ≥ 95th percentile for age and sex.

Abbreviations: SBP systolic blood pressure, DBP diastolic blood pressure, FG fasting glucose, TC total cholesterol, TG triglyceride.
