*ISO-BMI = age and gender-specific body mass index [BMI] for children up to 18 years. Cut-off point for overweight/obesity according to ISO-BMI defined by Cole et al. [19]. **WC = Waist Circumference. Cut-off points for overweight/obesity according to WC percentiles produced by McCarthy et al. [20]
