• Assessment
    In the oldest-old adults (age 85 and over), what is the predictive accuracy and maximum overestimation and underestimation resting metabolic rate (RMR) errors compared to measured RMR when using the Harris-Benedict formula?
    • 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 prediction accuracy and maximum overestimation and underrestimation errors in resting metabolic rate when using the Harris-Benedict formula?
    • Conclusion

      Individual errors in older adults can range from overestimation of RMR by 12% to underestimations by 27%in women and overestimation of RMR by 9% to underestimation of 19% in men. In normal weight men, 50 y or greater, the Harris-Benedict overestimated group mean RMR by <1% and the overestimate was within 3-4% when older adults representing all weight classifications were measured.
