BMI = body mass index; WC = waist circumference.
^{*}p < 0.05 for difference between boys and girls.
^{**}p < 0.001 for difference between boys and girls.
Post-Hoc Tests (Tukey HSD for continuous determinants and cross-tabulation (2x2) for dichotomous determinants):
A = difference between ‘overweight BMI and WC’ and ‘BMI only’.
B = difference between ‘overweight BMI and WC’ and ‘WC only’.
C = difference between ‘overweight BMI and WC’ and ‘not-overweight BMI and WC’.
D = difference between ‘BMI only’ and ‘WC only’.
E = difference between ‘BMI only’ and ‘not-overweight BMI and WC’.
F = difference between ‘WC only’ and ‘not-overweight BMI and WC’.
^{a}p < 0.05 for A and C.
^{b}p < 0.001 for A, C, D and F.
^{c}p < 0.001 for A, B, C, E, and F.
