A dinner meal is consumed by approximately 95% of preschool children, yet few studies have characterized the dinner meal within a broader environmental context. The primary goal of this study was to identify the average quantities of foods served and consumed at the dinner meal by preschool children. A secondary goal was to look at factors that influenced the total amounts of food and energy consumed among preschoolers at the dinner meal.
Food intake at a family dinner meal was measured using digital photography in African-American and Hispanic-American preschool children (n = 231). Pictorial records were converted to gram and energy estimates of food served and consumed; grams were converted to kilocalories for each food using Nutrition Data System for Research (NDSR) nutritional software. Foods were categorized by groups/subgroups. Comparison of means and coefficient of variation was examined overall and by food groups for food grams (and energy) served, consumed, and wasted. The relationship of mother/child characteristics to amounts served and consumed were analyzed by regression and analysis of variance (ANOVA).
Plate waste was high; 30% of the foods served to the child at the dinner meal were not consumed. The amounts of food and beverage served and consumed varied within and among the food groups studied. The proportion of children served a major food group at the dinner meal varied considerably: 44% fruit/juice, 97% vegetables, 99% grains, 97% meats, 74% dairy, 66% sweetened beverages, 92% fat and oils, and 40% sweets and sugars. The amount of food served was positively associated with the amount consumed (p < 0.0001). Energy density of the dinner meal was positively associated with energy intake consumed (p < 0.0001).
Plate waste and variation in amounts served and consumed was substantial. The amount of food served was positively associated with the amount of food consumed by preschool children.
大约 95%的学龄前儿童会吃正餐,但很少有研究从更广泛的环境背景来描述正餐。本研究的主要目的是确定学龄前儿童正餐所提供和消耗的食物的平均量。次要目标是研究影响学龄前儿童正餐总食物量和能量摄入的因素。
使用数字摄影术对非裔美国人和西班牙裔美国学龄前儿童(n=231)的家庭正餐进行食物摄入量测量。将图片记录转换为食物供应和消耗的克数和能量估计值;使用 Research 营养数据系统(NDSR)营养软件,将每种食物的克数转换为千卡。将食物按组/亚组进行分类。对所供应和消耗的食物克数(和能量)进行总体比较和食物组间比较,并比较组间变异系数。通过回归和方差分析(ANOVA)分析母亲/儿童特征与供应和消耗量的关系。
餐盘浪费率很高;儿童正餐所供应的食物中有 30%未被消耗。供应和消耗的食物和饮料量在研究的食物组内和组间存在差异。在正餐供应主要食物组的儿童比例差异很大:44%水果/果汁,97%蔬菜,99%谷物,97%肉类,74%奶制品,66%含糖饮料,92%脂肪和油,40%甜食和糖。所供应的食物量与消耗的食物量呈正相关(p<0.0001)。正餐的能量密度与消耗的能量摄入量呈正相关(p<0.0001)。
餐盘浪费以及供应和消耗的食物量存在很大差异。所供应的食物量与学龄前儿童消耗的食物量呈正相关。
