title: [Characterization of metabolic resting rate and proposal of a new equation for a female Brazilian population].
abstract: OBJECTIVE
  The goals of this study were to standardize resting metabolic rate (RMR) in the Brazilian female population and evaluate the suitability of the HB equation.
  
  
  METHODS
  In order to do so, 760 indirect calorimetry (CI) measurements performed in Brazilian female patients between 18 and 65 years old, were used. The results were tabulated, the population distributed according to the quintiles of weight, and the statistical analyses applied.
  
  
  RESULTS
  The average RMR varied from 1,226 to 1,775 calories/day. The HB equation overestimated the RMR by about 7%. From the correlation between the variables, we conclude that weight has a positive correlation with RMR and age a negative correlation.
  
  
  CONCLUSIONS
  The RMR and respiratory quotient (QR) can be used as obesity predictors. Two new equations were proposed in our study, one for the population with body mass index (BMI) > 35 kg/m(2) and another for the population with BMI < 35 kg/m(2).
