The lowest errors of estimation were obtained with the following quadratic polynomial regression equations for boys and girls (Figure 4.1) (Torun, 2001): Weight was selected as the single predictor, since it played a greater role than age in predicting TEE, and the exclusion of age from the predictive models did not increase the error of the estimate. Age and weight were highly correlated, with a tolerance of 0.078 among boys and 0.061 among girls. linear, multiple, polynomial, etc.) were evaluated, with age and/or body weight as predictors of TEE. Because many publications did not present results on individual children, the mean values for boys or girls of a specific age, or within a reasonably narrow age range, were used in the calculations, weighting the results of each study on the number of children. Predictive equations were derived from the studies of TEE. 4.2 Equations to predict total energy expenditure The inter-individual variability was similar to that observed with DLW among infants (18 percent for TEE/day, and 15 percent for TEE/kg/day see section 3.1). The overall mean coefficient of variation was 19 percent for energy expenditure calculated as TEE/day, and 17 percent when calculated as TEE/kg/day. Inter-individual coefficients of variation ranged from 9 to 34 percent within studies with DLW, and from 9 to 27 percent within studies with HRM. The Latin American children were four to 15 years old, and all lived in urban areas. Most (56 percent of the boys, 68 percent of the girls) were from the United States or the United Kingdom 18 percent of the boys and 18 percent of the girls were from Canada, Denmark, Italy, Sweden or the Netherlands and 26 percent of the boys and 14 percent of the girls were from Brazil, Chile, Colombia, Guatemala or Mexico. The studies reviewed for this consultation involved a total of 801 boys and 808 girls of one to 18 years of age (Torun, 2001). Therefore, studies using either DLW or HRM were included in this evaluation in order to encompass data on children and adolescents with a wider variety of lifestyles, and to include age groups with limited information, if based on DLW alone. The mean TEE measured with this technique is comparable with the mean value obtained using DLW or whole body calorimetry (Spurr et al., 1988 Ceesay et al., 1989 Livingstone et al., 1990 Livingstone et al., 1992 Emons et al., 1992 Maffeis et al., 1995 van den Berg-Emons et al., 1996 Davidson et al., 1997 Ekelund et al., 2000). On the other hand, several investigations on TEE of healthy, well-nourished children and adolescents have been done in a broader spectrum of countries and societies using minute-by-minute heart rate monitoring (HRM) and individual calibrations of the relationship between heart rate and oxygen consumption. in developing countries or poorer, largely rural societies). in developed countries or affluent societies) compared with countries and societies where cultural, economic, social and developmental circumstances require greater physical effort from an early age (i.e. However, most of the existing data on TEE measured with DLW were obtained in industrialized countries, where energy expenditure is influenced by modern technology, school environments, sedentary pastimes, mechanized transportation and social and economic support systems that demand relatively low physical effort (i.e.

Studies using the DLW technique were the starting point for estimating energy requirements of children and adolescents. 4.1 Measurement of total energy expenditure As the objective of this report is to make recommendations for healthy, well-nourished populations - thus excluding data from undernourished, overweight and stunted groups - the analysis was restricted to information from groups of healthy, well-nourished individuals. The 2001 expert consultation analysed a number of studies on TEE, growth and habitual activity patterns of children and adolescents in different parts of the world (Torun, 2001). This makes it possible to estimate energy requirements from measurements of TEE and energy needs for growth, rather than from food intake data or from estimates of time allocation and energy costs, as were previously used. In the 20 years since the 1981 joint FAO/WHO/UNU consultation (WHO, 1985), significant experimental evidence has been collected on the TEE of children and adolescents.
