a Transformations were applied to achieve normality (logBMI, 1/WC); b weight status categories were defined according to the criteria of the World Health Association [41]; c increased waist circumference was assessed by the International Diabetes Federation cut-offs [42]; means ± standard deviations for variables with normal distribution are shown. Medians and interquartile ranges (25th–75th) are shown for skewed variables. Categorical variables are displayed as absolute numbers and %. Student t-test was used to compare means of variables with a normal distribution. Mann–Whitney test was used to compare differences in non-normally distributed variables. Chi-square test was used to compare means of categorical variables. BMI: body mass index; WC: waist circumference.
