• Assessment
    In the oldest-old adults (age 85 and over), what is the prediction accuracy and maximum overestimation and understimation errors compared to measured resting metabolic rate when using the WHO/FAO/UNU predictive equation?
    • Conclusion

      There are insufficient studies to evaluate the applicability of the conclusion statement to oldest-old (i.e., populations aged 85 years or older).

    • Grade: V
      • 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.
    In older adults, what is the individual prediction accuracy and maximum overestimation and underestimation errors in estimating resting metabolic rate (RMR) compared to measured RMR when using the WHO/FAO/UNU formula?
    • Conclusion

      Individual prediction accuracy within +/- 10% is not reported for non-obese U.S.-residing adults using the World Health Organization/ Food & Agricultural Organization/United Nations University (WHO/FAO/UNU) equation.

       

      Individual error ranges in older adult males and females were overestimations by 7% and 12%, respectively to underestimations by 17% and 8%, respectively using the World Health Organization/ Food & Agricultural Organization/United Nations University (WHO/FAO/UNU) equation.

    • Grade: III
      • 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.
    In older adults, what is the group mean prediction accuracy and maximum overestimation and underestimation errors in estimating resting metabolic rate (RMR) compared to measured RMR when using the WHO/FAO/UNU formula?
    • Conclusion

      A group RMR mean underestimation error of 4% is reported using the World Health Organization/ Food & Agricultural Organization/United Nations University (WHO/FAO/UNU) equation in non-obese and underweight older adult Caucasian men. A separate study reports an group RMR mean overestimation by 3-9% in older adult, non-obese and obese Caucasian women.

    • 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.
