Demographic information for the study sample. IQR = interquartile range; BMI-for-age Z-scores used. The cutoffs for the weight categories were based on the World Health Organization standards and definitions [12]. The category of “slightly underweight” children was added as an intermediate category to include children between 1 and 2 standard deviations below the mean BMI-for-age.
