BMI body mass index
^aData are presented as mean ± standard deviation or n (%)
^bBody weight status was defined according to the World Health Organization reference data [20]
^cp values were assessed using multivariate analysis of variance (continuous variables) and a chi-squared test (categorical variable)
^dEffect sizes are considered negligible if < 0.2, small if between 0.2 and 0.5, moderate if between 0.5 and 0.8, and important if > 0.8
^eSample sizes for waist circumference were n = 5242 and n = 2976 for healthy-weight and overweight/obese, respectively
