目的：确定幼儿期常见食物的份量（一顿饭/零食摄入的数量）、时间稳定性以及与能量摄入、体重状况和社会人口特征的关系。研究、设计：评估了三个样本：1994 年至 1996 年、1998 年个人食物摄入量持续萨里 (CSFII 94-96, 98) (n = 1039)、 1977 年至 1978 年全国食品消费调查 (NFCS 77-78) (n = 10=15)，以及研究 12 至 18 个月的纵向样本 (n = 55)。对 CSFII 94-96,98 和 NFCS 77-78 样本进行比较以评估长期趋势。在纵向样本中评估了从 12 个月到 18 个月的变化。在 CSFII 94-96、98 样本中评估了份量大小与其他相关变量的关系。结果：近几十年来，大多数食品的份量仍然非常相似。肉类部分是个例外，在最近的样本中，肉类部分较小。大多数食品的比例在纵向上保持稳定，但磨坊、面包、麦片、果汁和花生酱的比例有所增加。体重与能量摄入和份量呈正相关，但与进食次数和/或食物的数量无关。从社会人口学角度来看，份量大小与进食场合和/或食物的数量成反比。结论：儿童主要通过份量大小来调节能量摄入。社会人口统计模式可能会对以后的体重状况产生影响。
Objective: To identify portion sizes (quantity ingested at a meal/snack) of foods commonly consumed in early childhood, temporal stability, and relations to energy intake, weight status, and sociodemographic characteristics.Study, design: Three samples were evaluated: the Continuing Surrey of Food Intakes by Individuals, 1994 to 1996, 1998 (CSFII 94-96, 98) (n = 1039), the Nationwide Food Consumption Survey, 1977 to 1978 (NFCS 77-78) (n = 10=15), and a longitudinal sample (n = 55) studied from 12 to 18 months. The CSFII 94-96,98, and NFCS 77-78 samples were compared to evaluate secular trends. Change from 12 to 18 months was assessed in the longitudinal sample. Relations of portion size to other relevant variables were evaluated in the CSFII 94-96, 98 sample.Results: In recent decades, portions remained remarkably similar for most foods. An exception was for meat portions, which were smaller in recent samples. Portions were longitudinally stable for most foods but increased for mills, bread, cereal, juice, and peanut butter. Body weight was positively related to energy intake and portion size but not number of eating occasions and/or foods. Sociodemographically, portion size was inversely related to number of eating occasions and/or foods.Conclusions: Children regulate energy intake largely through portion size. Sociodemographic patterns may have implications for later weight status.
