title: Resting energy expenditure in the obese: a cross-validation and comparison of prediction equations.
abstract: OBJECTIVE
  To examine the accuracy and precision of 12 equations or tables for predicting resting metabolic rate (RMR) in obese persons.
  
  
  METHODS
  Observational (correlational) study.
  
  
  METHODS
  Obesity Research Center, St Luke's/Roosevelt Hospital, New York, NY.
  
  
  METHODS
  One hundred twenty-six (73 women, 53 men) healthy, obese subjects recruited through the Obesity Research Center's Weight Control Unit.
  
  
  METHODS
  RMR by indirect calorimetry. Weight and height were measured to the nearest 0.1 kg and to the nearest 1 cm.
  
  
  METHODS
  Bivariate regression of predicted RMR on measured RMR; paired t tests for the difference between means of predicted RMR and measured RMR.
  
  
  RESULTS
  Of the 12 prediction equations, 6 had intercepts or slopes that were significantly different from 0 and 1, respectively. With two exceptions, the equations accounted for between 56% and 63% of the variance in measured RMR. The Robertson and Reid (1952) equation and the Fleisch (1951) equation performed best with our obese sample.
  
  
  CONCLUSIONS
  The Robertson and Reid (1952) and the Fleisch (1951) equations are recommended for clinical use with obese patients.
