| Summary: | 碩士 === 輔仁大學 === 食品營養學系 === 87 === The purpose of the study was to examine the validity of 24-hour dietary recall to assess nutrient intakes among young children. Sixty-one (28 boys, 33 girls) children attending preschool at the age of 3-6 were recruited. Trained observers weighed and recorded all foods eaten by young children and collected the menus and recipes of preschools the day before the interviews. Twenty-four hour dietary recalls were taken by interviewers. Mothers, preschool teachers and children were required to recall the food eaten. Dietary assessment aids were used to facilitate the recall. The recalled intakes were compared with actual food intakes and preschool recipes according to food item, weight, energy and nutrient intakes. The results showed that the recall accuracy was about 80% for food items either by mothers or teachers, however teachers could recall more accurately than mothers. For food weight, underestimation was more frequent than overestimation, 70% of foods were recalled within +75% of actual food weight. When energy and nutrient intakes of young children were classified to tertile or quintile, teachers had higher accuracy than mothers. The correlation coefficients were statistically significant when comparing actual intakes to that of recalls by both mothers and teachers. Except for a few nutrients, it had good correlations between actual intakes and school recipes, but the correlation coefficients were lower than that between actual intakes and teachers’ recalls. No influence of mothers’ education level was found between actual intakes and recalls, however, the correlation coefficients between actual intakes and recalls were lower among low educated mothers than that of high educated mothers. In conclusion, 24-hour recall by mothers and teachers could accurately estimated young children’s actual food and nutrient intakes. Calculated average food provision for children from school recipes could be used to substitute teachers’ recall to simplify recall procedure. In all, using 24-hour dietary recall could be used to assess young children’s diet intake.
