  • Assessment
    In obese adults, what is the prediction accuracy and maximum overestimation and understimation errors compared to measured resting metabolic rate when using the Owen et al formula?
    • Conclusion

      The Owen, et al. equation predicted RMR within 10% of measured RMR in obese (BMI 30-40 kg/m2) individuals by 75% with the remaining 25% including 5% overestimations and 20% underestimations. In the same study, the Owen, et al. equation predicted RMR within 10% of measured RMR in 33% of severely obese (BMI >40 kg/m2) individuals with the remaining 67% including 7% overestimations and 60% underestimations. The individual error range was a maximum overestimate of 15% to a maximum underestimate of 37%.

    • Grade: II
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.
