All other weights from Annex 1. to increase energy expenditures and thus counter the possible current down- ward trend in physical activity. 2.1.5 Estimated Average Requirements The Panel found that the measure- ments of total energy expenditure using DLW were on average in agreement with observed dietary energy intakes from modern infant formulas and with FAO/WHO/UNU values without the 5 per cent increment. The EARs for energy for infants are summarised in Table 2.1 and were derived by combining the evidence from different sources outlined above. The figures are intended only for formula-fed infants and assume that the Southgate and Durnin factors!8 are used to estimate the metabolisable energy content of foods. In the absence of contradictory evidence the EARs for boys and girls are assumed to be identical when expressed on a body weight basis. 2.1.6 Research needs ‘The Panel noted the recent reports which link slower growth during the first year of life to higher risk of ill health during adulthood, and recognised the need for more detailed information on the effects of nutrition and growth during fetal development, infancy and childhood on later well-being?°. 2.2 Energy requirements of children aged 3-10 years 2.2.1 The Panel found insufficient data to calculate EARs based on measure- ments of energy expenditure in children aged 3 to 10 years. Therefore, the Panel accepted that EARs should be based on intakes. 2.2.2 There are a number of studies which provide data for the UK on energy intakes in this age group2!-25. These are consistent with the values quoted as ‘Intakes’ by FAO/WHO/UNU:%. The Panel therefore accepted these values as
