  1. aSubjects were classified based on BMI cutoffs [29]
  2. b FFM fat-free mass
  3. c FM fat mass
  4. dTotal energy expenditure measured by doubly labeled water of all subjects
  5. eResting energy expenditure was predicted by equation of Kaneko et al. [26]
  6. fPhysical activity level was calculated as TEEDLW / predicted REE [26]
  7. gWe excluded the data of two boys and two girls because of insufficient pedometer wearing time
  8. hTEEDLW excluding overweight and obese subjects on the basis of BMI cutoffs [29]
  9. iAnalysis of covariance on each characteristics, adjusting for measurement timing
