Summary

Assessment of resting energy expenditure (REE) by indirect calorimetry (IC) in 1400 healthy individuals for arithmetical transformation into an bedside tool to estimate energy requirements in dietary practice (BASAROTs). A multinational, multicenter, prospective cross-sectional study.

Detailed description

The assessment of energy expenditure is the basic requirement for any nutritional therapy. Nevertheless, there is still no accurate, scientifically validated and practical bedside tool. The reference method for energy expenditure measurement is indirect calorimetry (IC). High costs, time requirements and the need for trained personal are main reasons for its limited use in clinical practice. Also arithmetical calculations, such as the Harris-Benedict equation, are not widely accepted. In general energy expenditure is often estimated by so called rules of thumbs, a method requiring only one multiplication with body weight (for example: 25 kcal/kg body weight). Sex, age and BMI are usually not considered, although they are independent predictors of energy expenditure. Thus, energy expenditure estimations are often inaccurate, especially in older and overweight/obese persons. Therefore, it is important to develop a bedside tool that is more accurate but simple enough to be accepted by practitioners. In 2004, the Austrian Society of Clinical Nutrition published the first BMI, aged and sex adapted rule of thumbs, called BASAROTs (BMI Age Sex Adjusted Rule Of Thumbs). Those were, however, based on results of the Harris Benedict equation. The main objective of the present study is, therefore, to replace the existing BASAROTs by BASAROTs based on actual measurements of resting energy expenditure by indirect calorimetry (IC-BASAROTs).
