EE: Mifflin-St. Jeor: Older Adults (2005)

  • Assessment
    In older adults, what is the group mean error in estimating resting metabolic rate (RMR) compared to measured RMR when using the Mifflin-St. Jeor formula?
    • Conclusion
      The Mifflin-St. Jeor equation underestimates RMR in males by a group mean of 5% and in Caucasian women by 4-11% (mean age 61 y +/- 8 y and 67.1 +/- 4.4 y), representing a group mean of  60 kcal/day difference.   
    • Grade: II
      • Grade I means there is good evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited;
      • Grade IV is Expert Opinion;
      • Grade V is Not Assignable.
    • Evidence Summary: Mifflin-St. Jeor Group Mean Errors: Older Adults
    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 Mifflin-St. Jeor formula?
