  1. aTEE measured by doubly labeled water (DLW) method
  2. bTEE estimated by equation of Dietary Reference Intakes (DRI) for Japanese [4], basal metabolic rate (BMR) standard (kcal/kg/d) × body weight (kg) × PAJ-DRI (physical activity coefficient)
  3. cTEE estimated by equation of Institute of Medicine (IOM) [5]
  4. dTEE estimated by equation of FAO (Food and Agriculture Organization of the United Nations) [12]
  5. eRoot mean squared error
  6. fPercentage of the subjects predicted by equation within ± 10% of measured TEE
  7. gPercentage of the subjects predicted by equation < 90% of measured TEE
  8. hPercentage of the subjects predicted by equation > 110% of measured TEE
  9. *Significantly different from TEEDLW, p < 0.05 (repeated measures analysis of covariance with Bonferroni correction, adjusting for measurement timing)
  10. Signigicantly correlate with TEEDLW, p < 0.05 (Partial correlation coefficient, adjusting for measurement timing)
