• Assessment
    In older adults, what is group mean error 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.
    In the oldest-old adults (age 85 and over), what is the group mean error in estimating resting metabolic rate (RMR) compared to measured RMR when using the WHO/FAO/UNU formula?
    • Conclusion

      There are insufficient studies to evaluate the magnitude of group mean errors in estimating resting metabolic rate in the oldest-old (i.e., populations aged 85 years or older).
