| Research Abstract |
Recently, it has been investigated about obesity in preschool children. We also recognized to have decreased in their physical activity at daily life. Therefore, we must be known about energy requirements throughout childhood in order to optimum the nutritional program for preschool children. So, we carried out the measurement of energy intake by food records and energy expenditure by time allocation study, resting metabolism by Teem-100 (Metabolic Analysis System) using 94 healthy children from 1 to 5 years old. And we compared results obtained with energy requirements reported in Dietary reference index. Energy and nutrients intake of preschool children achieved the standard values reported in Dietary reference index for the Japanese. Furthermore, high salt and low dietary fiber in intake were obvious. Energy expenditure balanced energy intake, nevertheless both values were smaller than the standard values reported in Dietary reference index for the Japanese. But, energy intake per kilogram body weight was higher than energy expenditure per kilogram body weight. Especially, those of 2 years old and 5 years old preschool children were the highest among them. And energy (kcal/day) per day, per capita based energy (kcal/min) by RQ and VO_2, was lower than Dietary reference index for the Japanese.
Moreover, in this study we calculated energy expenditure using the energy expenditure (Ea). Because, energy intake of preschool children was consistent with Ea rather than the activity factor (Af). For using Af as energy expenditure of preschool children, Af for preschool children is necessary.
