摘要：This study examined the validity of nursery teachers1 report on the physical activity of young children. Subjects were twenty-one children aged 3 to 4 years (12 boys and 9 girls) at a nursery in Toyama Prefecture, Japan. Children wereequipped with the Actiwatch (Mini-mitter Company Inc.) activity monitor and the Caloriecounter Select U (Kenz, Co, Ltd) for three consecutive weekdaysto assess their daily physical activity levels. Nursery teachers completed a questionnaire containing questions on chil-dren's activity level during the measurement periods at the nursery. The results showed that subjects with a high frequency of physical activity were significantly associated with an increasing trend in total energy expenditure and activity counts per day. Children whose physical activity was rated as "very often11 had a significantly higher activity level per day from the Actiwatch instrument, compared with peers whose physical activity was rated as "not often" (570.5q•192.8 counts vs. 334.9*123.4 counts, p<0.05). Regarding energy expenditure originating from physical activity and steps per day from the Caloriecounter, a significant difference was found between "very active" children and "inactive" children as rated by the nursery teachers (140.7*17.5 kcal vs. 78.2*17.4 kcal, p<0.05; 16103*1896 steps vs. 10038*32 steps, p<0.05). This study indicates that children's physical activity level as reported by their teachers in nursery surroundings is in accordance with the objective data from the Actiwatch and the Caloriecounter. The results suggest that nursery teachers' respondent for children in physical activity may be used as a valid measure to evaluate young children's physical activity levels, especially in nursery setting.
