Notes: Numerical data are presented as mean values (95.0% lower-upper confidence interval), and Student’s t-test was used for the difference of continuous variables between genders adjusted for age and gender. Categorical data are presented by number and %, and a Chi-square test was used to evaluate the difference between genders. P value is significant at ≤0.05.

Abbreviations: BMI, body mass index; WC, waist circumference; MeS, metabolic syndrome; ow and ob, overweight and obese; TC, total cholesterol; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; TG, triglycerides; SBP, systolic blood pressure; DBP, diastolic blood pressure.

Figure 1 Frequency of individual MeS components (%) in all subjects and according to overweight/obesity status.

Notes: The P value indicates the difference in frequency distribution of individual MeS components between non-ow & non-ob and ow/ob children. A level of P < 0.05 is statistically significant.
Abbreviations: WC, waist circumference; MeS, metabolic syndrome; ow and ob, overweight and obese; non-ow and non-ob, non-overweight and non-obese; HDL-C, high-density lipoprotein cholesterol.

Notes: The P value indicates the difference in frequency of clustering of MeS components between non-ow and non-ob and ow/ob children. A level of P < 0.05 is statistically significant.
Abbreviations: ow and ob, overweight and obese; non-ow and non-ob, non-overweight and non-obese.
