cm, centimetres; m, meters; SD, standard deviation. ^{a} Healthy weight, overweight or obese classified using the UK age and gender-specific
BMI z-score cut-off points that correspond to a BMI of 25 for overweight and 30 for
obese at 18 years of age. * *P*-values for the comparison of excluded participants and remaining participants using
the students t-test (two-tailed) were not significant (*P* > 0.05). †*P*-values for the comparison of excluded participants and remaining participants using
the Wilcoxon test (two-tailed) were not significant (*P* > 0.05).
