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.
Quality of Reviewed Studies
The WHO/FAO/UNU equation has been tested for prediction accuracy in five U.S. and Canadian-residing populations (Arciero, Arciero, Case, Garrel and Taaffe). International studies represented Italy (Siervo, 2003; Scalfi, 1993 and Censi, 1998) and Germany (Luhrman. 2002). Of the eight studies, four instituted a methodologically sound standardized protocol for measuring indirect calorimetry.
Garrel studied 67 (39 male, 28 female) normal weight healthy individuals and found that the WHO/FAO/UNU equation formula predicted RMR within 10% of the measured value for 100% of the subjects. However, standard errors reported are unclear and may lead to inaccurate conclusions and were not used in the final Conclusion Statement.
