Purposes of this study were to describe the nutrient intake of upper elementary children by age and sex and to demonstrate criterion-related validity for the performance device, What I Usually Eat (National Dairy Council and Iowa State University, 1980). The device was designed to be used by teachers as an alternative method for estimating children's food intake;The parents of the 67 fourth and sixth graders who participated in the study kept detailed 7-day food records of their children's food intake. Female students comprised 55% of the sample. Average daily intakes of nutrients were calculated by age-sex groups. Nutrient intakes were compared to the 1980 Recommended Dietary Allowances (RDA) (Food and Nutrition Board, National Research Council);Carbohydrates, iron, and calcium were the nutrients most often found below the 1980 RDA. Individual RDA for protein and vitamin A were over 100% for all subjects. Meal patterns differed from snack patterns with less nutrient-dense and higher sugar content foods being eaten for snacks;The participating children responded to the performance device at school. They selected from 40 food cards, displayed on a pegged board, those foods that were representative of what they would typically eat in one day. Their parents responded to the device during a personal interview. The 40 food cards represented foods from the Basic Four Food Groups, used as the standard, and a group of foods not making significant nutrient contributions that were designated as other;Parents' and childrens' device scores and mean dietary intake of each child were calculated by food group from the individual 7-day food records. These responses were compared by food group using a two-way analysis of variance. Orthogonal comparisons using t-tests were computed between parent-child device scores and parent-child device scores/reported intake scores;A significant difference between parent-child means for the fruit/vegetable group was noted. Parent-child/reported scores differed significantly for all food groups. The children were more accurate in estimating reported intake than their parents in the critical areas of fruit/vegetable and milk consumption. These responses demonstrate criterion-related validity for the device;What I Usually Eat provides one measure of what children eat. Use of the device enables teachers to identify areas of possible nutrient insufficiency and to teach to these needs.
