^aThe difference between the adiposity levels is significant at the 0.05 level (2-tailed)
Data are mean ± Standard Deviation. BMD was scaled to the adiposity levels (WC: < 90 cm for males and < 80 cm for females was normal; ≥90 cm for males and < 80 cm for females was obesity; WHR: < 0.9 for males and < 0.85 for females was normal; ≥0.9 for males and ≥ 0.85 for females was obesity; WHtR: < 0.5 was normal; ≥0.5 was obesity; BMI: < 28.0 kg/m² was normal/overweight; ≥28.0 kg/m² was obesity; BFP%: < 25% for males and < 35% for females was normal; ≥25% for males and ≥ 35% for females was obesity; VFI: < 9 was low; ≥9 was high)
