The day-to-day variations of energy and nutrient intake were studied in infants aged 4, 9, 15 and 24 months. There were 40, 40, 38 and 40 infants in the four groups, respectively. In the 4-month-old infants 3-day weighed food records were used, and in the infants of the other three ages, 7-day weighed food records. The smallest number of daily records required to classify the individual infants into the correct category with low or high intake with a specified degree of accuracy was calculated. Fewer daily records for energy and nutrient intake were needed for the 4-month-old infants than for the older ones.
对4个月、9个月、15个月和24个月大的婴儿的能量和营养摄入量的日常变化进行了研究。四组婴儿分别有40名、40名、38名和40名。对于4个月大的婴儿，使用了为期3天的称重食物记录；对于其他三个年龄段的婴儿，则使用了为期7天的称重食物记录。计算了将个体婴儿准确分类为低摄入量或高摄入量正确类别的所需的最少每日记录数。4个月大的婴儿所需的能量和营养摄入量的每日记录比年龄较大的婴儿少。
