    Additional information

    For the present FAO/UNU/WHO report, an extensive set of measurements was compiled from the literature. The data base covers some 11 000 technically acceptable measurements on individuals of both sexes and all ages, who were considered to be healthy. It includes adults of different stature and of different weight for height, as well as individuals who fell within the designated range of “acceptable” weight for height. The data also include some children and adults who may have been on limited energy intakes before the BMR measurement. This may partly explain the lower BMRs in some groups.

    A number of studies have attempted to assess the possibility of ethnic differences in BMR but these have failed to identify any differences that could not be related to the nutritional state or possibly to climatic conditions. Therefore, all studies have been incorporated into a single data base for developing the FAO/WHO/UNU equations.

    Result interpretation

    Geschat basaalmetabolisme in KJ/dag gebaseerd op het rapport van de Food and Agriculture Organization (FAO), United Nations Universtity (UNU) en de World Health Organization (WHO). 

    Hoe dit model kan worden gebruikt:
    Om onder- of overvoeding te voorkomen, dient de calorische intake te worden afgestemd op de energiebehoefte van de individuele patiënt. Het gebruik van formules om de individuele energiebehoefte te schatten heeft daarmee de voorkeur boven het aanhouden van een vaste calorische intake (bijvoorbeeld 30 kcol/kg) per patiënt. 

    In een retrospectieve validatie studie verricht tussen juli 2002 en april 2005 door Weijs et al., werden 18 verschillende formules voor het berekenen van het basaalmetabolisme geëvalueerd. In totaal werden 48 polikliinische en 45 klinische patiënten geïncludeerd voor wie indirecte calorimetrische data beschikbaar was. Daarnaast werd een subgroep van 42 patiënten met ondergewicht BMI < 18.5 kg/m2) geanalyseerd. Van alle geëvalueerde formules, gaf de FAO/UNU/WHO vergelijking de beste schatting met een afwijking van 764, 1163 en 920 KJ/dag voor respectievelijk poliklinische, klinische patiënten en patiënten met ondergewicht. Goede alternatieven bleken de Mifflin formules (met name voor patiënten met ondergewicht) en de gereviseerde Harris & Bennedict formule.
