Abstract

OBJECTIVES

To assess the usual nutrient intakes of 3,273 US infants, toddlers, and preschoolers, aged 0 to 47 months, surveyed in the Feeding Infants and Toddlers Study (FITS) 2008; and to compare data on the usual nutrient intakes for the two waves of FITS conducted in 2002 and 2008.

DESIGN

The FITS 2008 is a cross-sectional survey of a national random sample of US children from birth through age 47 months. Usual nutrient intakes derived from foods, beverages, and supplements were ascertained using a telephone-administered, multiple-pass 24-hour dietary recall.

SUBJECTS

Infants aged birth to 5 months (n=382) and 6 to 11 months (n=505), toddlers aged 12 to 23 months (n=925), and preschoolers aged 24 to 47 months (n=1,461) were surveyed.

METHODS

All primary caregivers completed one 24-hour dietary recall and a random subsample (n=701) completed a second 24-hour dietary recall. The personal computer version of the Software for Intake Distribution Estimation was used to estimate the 10th, 25th, 50th, 75th, and 90th percentiles, as well as the proportions below and above cutoff values defined by the Dietary Reference Intakes or the 2005 Dietary Guidelines for Americans.

RESULTS

Usual nutrient intakes met or exceeded energy and protein requirements with minimal risk of vitamin and mineral deficiencies. The usual intakes of antioxidants, B vitamins, bone-related nutrients, and other micronutrients were adequate relative to the Adequate Intakes or Estimated Average Requirements, except for iron and zinc in a small subset of older infants, and vitamin E and potassium in toddlers and preschoolers. Intakes of synthetic folate, preformed vitamin A, zinc, and sodium exceeded Tolerable Upper Intake Level in a significant proportion of toddlers and preschoolers. Macronutrient distributions were within acceptable macronutrient distribution ranges, except for dietary fat, in some toddlers and preschoolers. Dietary fiber was low in the vast majority of toddlers and preschoolers, and saturated fat intakes exceeded recommendations for the majority of preschoolers. The prevalence of inadequate intakes, excessive intake, and intakes outside the acceptable macronutrient distribution range was similar in FITS 2002 and FITS 2008.

CONCLUSIONS

In FITS 2008, usual nutrient intakes were adequate for the majority of US infants, toddlers, and preschoolers, except for a small but important number of infants at risk for inadequate iron and zinc intakes. Diet quality should be improved in the transition from infancy to early childhood, particularly with respect to healthier fats and fiber in the diets of toddlers and preschoolers.

摘要

目的

评估参与2008年婴幼儿喂养研究(FITS)的3273名美国0至47个月的婴儿、幼儿和学龄前儿童的日常营养素摄入量;并比较2002年和2008年进行的两期FITS中日常营养素摄入量的数据。

设计

2008年FITS是一项对从出生到47个月的美国儿童进行的全国随机抽样横断面调查。通过电话进行的多次24小时膳食回顾确定了来自食物、饮料和补充剂的日常营养素摄入量。

对象

调查了出生至5个月的婴儿(n = 382)、6至11个月的婴儿(n = 505)、12至23个月的幼儿(n = 925)以及24至47个月的学龄前儿童(n = 1461)。

方法

所有主要照料者完成一次24小时膳食回顾,一个随机子样本(n = 701)完成第二次24小时膳食回顾。使用个人电脑版的摄入量分布估计软件来估计第10、25、50、75和90百分位数,以及低于和高于膳食参考摄入量或《2005年美国膳食指南》定义的临界值的比例。

结果

日常营养素摄入量满足或超过了能量和蛋白质需求,维生素和矿物质缺乏风险极小。抗氧化剂、B族维生素、与骨骼相关的营养素和其他微量营养素的日常摄入量相对于适宜摄入量或估计平均需求量是充足的,但一小部分较大婴儿的铁和锌摄入量、幼儿和学龄前儿童的维生素E和钾摄入量除外。相当一部分幼儿和学龄前儿童的合成叶酸、预成维生素A、锌和钠的摄入量超过了可耐受最高摄入量。除了一些幼儿和学龄前儿童的膳食脂肪外,宏量营养素分布在可接受的宏量营养素分布范围内。绝大多数幼儿和学龄前儿童的膳食纤维含量较低,大多数学龄前儿童的饱和脂肪摄入量超过了推荐量。2002年FITS和2008年FITS中摄入不足、摄入过量以及超出可接受宏量营养素分布范围的比例相似。

结论

在2008年FITS中,大多数美国婴儿、幼儿和学龄前儿童的日常营养素摄入量是充足的,但有一小部分但数量可观的婴儿存在铁和锌摄入不足的风险。从婴儿期到幼儿期的过渡阶段应改善饮食质量,特别是在幼儿和学龄前儿童的饮食中增加更健康的脂肪和纤维。
