To assess the nutrient adequacy of the diets of US infants and toddlers 4 to 24 months of age.
Descriptive analysis of the usual nutrient intakes of infants and toddlers using 24-hour recall data from the 2002 Feeding Infants and Toddlers Study.
A national random sample of 3,022 infants and toddlers, with 2 days of recall available for 703 sample members. Sample sizes by age were: infants 4 to 6 months (n=862), infants 7 to 11 months (n=1,162), and toddlers 12 to 24 months (n=998).
Using the personal computer version of the Software for Intake Distribution Estimation, we estimated (where applicable) the percentage of infants and toddlers with usual intakes below the estimated average requirement, compared the means of usual nutrient intake distributions with adequate intake levels, and compared the 99th percentile of usual intake distributions with tolerable upper intake levels.
For infants under 12 months of age, mean usual intakes exceeded the adequate intake for all nutrients. For toddlers 12 to 24 months of age, the estimated prevalence of inadequacy was low for most nutrients; however, 58% of toddlers had usual vitamin E intakes less than the estimated average requirement. Mean energy intake exceeded the estimated energy requirement by 10% for infants 4 to 6 months, 23% for infants 7 to 12 months, and 31% for toddlers 12 to 24 months of age. The discrepancy between mean energy intake and the estimated energy requirement for infants 4 to 6 months of age was larger for infants fed solids than for infants consuming only breast milk or formula. Fiber intakes of toddlers were below the adequate intake.
Studies should examine whether parents overreport foods consumed by infants and toddlers, and whether infants and toddlers are consuming more energy than required. Additional research is indicated to substantiate some of the new Dietary Reference Intakes for infants and children 1 to 3 years of age.
评估美国4至24个月大婴幼儿饮食中的营养素充足情况。
利用2002年婴幼儿喂养研究中的24小时回忆数据,对婴幼儿通常的营养素摄入量进行描述性分析。
全国范围内随机抽取3022名婴幼儿,其中703名样本成员有两天的回忆数据。各年龄段的样本量分别为:4至6个月的婴儿(n = 862),7至11个月的婴儿(n = 1162),以及12至24个月的幼儿(n = 998)。
使用个人电脑版的摄入量分布估计软件,我们(在适用的情况下)估计了通常摄入量低于估计平均需求量的婴幼儿百分比,将通常营养素摄入量分布的均值与适宜摄入量水平进行比较,并将通常摄入量分布的第99百分位数与可耐受最高摄入量水平进行比较。
对于12个月以下的婴儿,所有营养素的平均通常摄入量均超过适宜摄入量。对于12至24个月的幼儿,大多数营养素摄入不足的估计患病率较低;然而,58%的幼儿通常维生素E摄入量低于估计平均需求量。4至6个月的婴儿平均能量摄入量比估计能量需求量高10%,7至12个月的婴儿高23%,12至24个月的幼儿高31%。4至6个月大的婴儿中,喂食固体食物的婴儿平均能量摄入量与估计能量需求量之间的差异比仅食用母乳或配方奶 的婴儿更大。幼儿的纤维摄入量低于适宜摄入量。
研究应调查父母是否高估了婴幼儿的食物摄入量,以及婴幼儿是否摄入了超过需求量的能量。需要进行更多研究来证实1至3岁婴幼儿的一些新的膳食参考摄入量。
