BMI body mass index, IQR interquartile range, SDS standard deviation scores, n = count,  % = percentage. *BMI > 90th and **BMI > 97th age- and sex-specific percentile, according to the national German reference [53]. P-values of the difference between sexes were obtained from Wilcoxon-Mann–Whitney test
