To examine average portion sizes consumed per eating occasion by infants and toddlers. Average portions reported for toddlers were compared to average portions for comparably aged children reported in the 1994 to 1996 and 1998 Continuing Survey of Food Intakes by Individuals. In addition, reported average portions were compared with minimum required portion sizes for meals served to infants and toddlers in the Child and Adult Care Food Program (CACFP).
Data from 24-hour recalls collected in the 2002 Feeding Infants and Toddlers Study (FITS) were analyzed. Average portion sizes were determined for major food groups and individual foods that were reported by at least 5% of the population. Most foods were reported separately; however, sandwiches were disaggregated into their components. Gram weights of portions consumed were converted, on a food-by-food basis, to household units so that foods with different volume-to-weight ratios could be analyzed together.
SUBJECTS/SETTING: A national random sample of 3,022 US infants and toddlers 4 to 24 months of age.
For each food and food group, average portion sizes per eating occasion were computed for up to six age groups. An average per-eating occasion portion was determined for each child who consumed a given food by summing the total amount of food consumed over the day and dividing by the number of eating occasions. These estimates were then summed across all children who consumed the food and divided by the total number of consumers. The number of eating occasions was defined as the total number of times a child had anything to eat or drink during the day, excluding eating occasions that included only water and/or supplements.
For most foods, there was a gradual increase in the average portion as age increased. Average portions reported for FITS toddlers were consistent with those reported for comparably aged children in the most recent Continuing Survey of Food Intakes by Individuals. The average portions reported for FITS infants and toddlers were consistent with CACFP-recommended portion sizes for formula, juice, meats, and cheese. For milk (toddlers only), cereal, breads, fruits, and vegetables, average portions reported in FITS were consistently larger than CACFP portion sizes. Distributions showed that, in many cases, the per-eating occasion portion sizes of 50% to 90% of FITS infants and toddlers exceeded the CACFP portion sizes.
Dietitians, pediatricians, and health educators can use the data presented in this article to provide guidance to parents and caregivers about reasonable portion sizes for infants and toddlers. The data should also be useful to those who plan meals for infants and toddlers in child care settings and to researchers studying dietary intakes of infants and toddlers. Advice about reasonable portion sizes should always be tempered with appropriate cautions about avoiding coercive "clean your plate" feeding practices. Parents and caregivers should be encouraged to offer infants and toddlers appropriate portions of healthful foods from the basic food groups, with a special emphasis on fruits, vegetables, and whole grains, and allow them to eat until they are satiated.
研究婴幼儿每次进食时的平均食量。将所报告的幼儿平均食量与1994年至1996年以及1998年“个人食物摄入量持续调查”中所报告的同龄儿童平均食量进行比较。此外,将所报告的平均食量与儿童及成人护理食品计划(CACFP)中为婴幼儿提供的膳食最低所需食量进行比较。
对2002年婴幼儿喂养研究(FITS)中收集的24小时膳食回顾数据进行分析。确定至少5%的人群报告的主要食物类别和单一食物的平均食量。大多数食物单独报告;然而,三明治被分解为其组成部分。所食用部分的克重逐食物转换为家庭单位,以便能够一起分析具有不同体积与重量比的食物。
对象/场所:对3022名4至24个月大的美国婴幼儿进行全国随机抽样。
对于每种食物和食物类别,计算多达六个年龄组每次进食时的平均食量。对于食用特定食物的每个儿童,通过将一天中所食用食物的总量相加并除以进食次数来确定每次进食的平均食量。然后将这些估计值在所有食用该食物的儿童中求和,并除以消费者总数。进食次数定义为儿童一天中吃或喝任何东西的总次数,不包括仅包含水和/或补充剂的进食情况。
对于大多数食物,平均食量随着年龄增长而逐渐增加。FITS幼儿所报告的平均食量与最近一次“个人食物摄入量持续调查”中同龄儿童所报告的食量一致。FITS婴幼儿所报告的平均食量与CACFP推荐的配方奶、果汁、肉类和奶酪的食量一致。对于牛奶(仅针对幼儿)、谷类食品、面包、水果和蔬菜,FITS中所报告的平均食量一直大于CACFP的食量。分布情况表明,在许多情况下,50%至90%的FITS婴幼儿每次进食的食量超过了CACFP的食量。
营养师、儿科医生和健康教育工作者可以利用本文提供的数据,为家长和照料者提供有关婴幼儿合理食量的指导。这些数据对于在儿童保育机构为婴幼儿制定膳食计划的人员以及研究婴幼儿饮食摄入量的研究人员也应是有用的。关于合理食量的建议应始终辅以适当的告诫,避免强制实行“吃完盘子里的食物”的喂养方式。应鼓励家长和照料者为婴幼儿提供来自基本食物类别的适量健康食物,特别强调水果、蔬菜和全谷物,并让他们吃到饱足。
