title: Resting metabolic rate of Vietnamese adolescents.
abstract: OBJECTIVE
  To evaluate the FAO/WHO/UNU equations for predicting resting metabolic rate (RMR) in Vietnamese adolescents.
  
  
  METHODS
  A cross-sectional study involving healthy subjects was carried out at the Basic Nutrition Department, National Institute of Nutrition, Vietnam. The RMR was measured by indirect calorimetry and anthropometric indices were recorded. Equations derived by linear regression of RMR and body weight were compared to the FAO/WHO/UNU (1985) predictive equations.
  
  
  METHODS
  A total of 110 subjects who had normal body mass index (5-85 percentile) and divided into two groups by sex.
  
  
  RESULTS
  Mean RMRs (MJ/kg/day) were 0.1146+/-0.0054 for males and 0.1062+/-0.0103 for females. Compared to the FAO/WHO/UNU equation, our findings were 7.8% and 11.7% lower in the two groups, respectively (P<0.001).
  
  
  CONCLUSIONS
  Our findings suggest that the FAO/WHO/UNU equations may overestimate RMR in Vietnamese adolescents. Further studies on establishing reference of daily energy needs for Vietnamese adolescents should be carried out.
