Nutritional studies during childhood: IV Energy and nutrient intake at age 4.
A study of the usual nutrient intake of a sample of 183 healthy 4 year olds is reported. These children have been the subject of a longitudinal study from birth. Data include daily intakes of food energy, protein, fat, carbohydrate, fibre, minerals, and vitamins. Minor differences in nutrient intake were present between the sexes. Overall nutrient intakes were at a slightly lower level than those described previously. The methodological considerations of such a community nutrition study are discussed, including the intrinsic sources of error which may have contributed to the observed differences. Changes in recreational activity level and influences of climate may also be important factors affecting food energy and nutrient intake at this age.
