背景资料：较大的部分大小的食物和饮料可能会影响整体能量摄入量在膳食和促进overeating.Objective：我们调查的能量密集的食物和能量摄入量在美国儿童和青少年的饮食场合的部分大小的趋势。设计：从1977年至2006年的四个美国全国代表性调查进行了分析（n = 31,337）。我们测量了所选食物[含糖饮料（SSB），咸味小吃，甜点，炸薯条，汉堡包，比萨饼和墨西哥快餐]的部分大小（kcal，g和mL）和能量摄入量（kcal）的趋势。趋势报告的年龄组（2-6-，7-12-，和13-18岁），性别，和社会经济地位。结果：在2003-2006年，所选的食物占每日能量摄入量的38%，在13-18岁，35%的每日能量摄入量的7-12岁，和28%的每日能量摄入量的2-6岁。在所有年龄组中，较大份量的比萨饼与食用比萨饼时较高的能量摄入量相一致。在7-12岁和13-18岁的青少年中，膳食中较高的能量摄入量与较大份量的SSB，炸薯条或咸味小吃相吻合。在所有年龄组中，墨西哥快餐的较大份额与膳食中较高的能量摄入量有关，但不显着。青春期男孩在所有时间段的食物摄入量和能量摄入量均高于女孩（P < 0.01）。从比萨饼在一顿饭中的千卡的百分比增加更急剧的非西班牙裔非洲裔美国人，在西班牙裔，并在组与低家庭教育比其他groups.Conclusions：青少年更容易增加部分大小比年幼的孩子。非西班牙裔非裔美国人和西班牙裔美国人以及受教育程度较低的个人群体是公共卫生政策的主要关切。美国临床营养杂志2011;94：1324-32。
Background: Larger portion sizes of foods and beverages could affect overall energy intake at meals and promote overeating.Objective: We investigated trends in portion sizes of energy-dense foods and energy intakes at eating occasions in US children and adolescents.Design: Four US nationally representative surveys from 1977 to 2006 were analyzed (n = 31,337). We measured trends in portion sizes (kcal, g, and mL) of selected foods [sugar-sweetened beverages (SSBs), salty snacks, desserts, French fries, burgers, pizzas, and Mexican fast foods] and energy intake (kcal) at eating occasions during which selected foods were consumed. Trends were reported by age group (2-6-, 7-12-, and 13-18-y-olds), sex, and socioeconomic status.Results: In 2003-2006, the selected foods accounted for 38% of daily energy intake in 13-18-y-olds, 35% of the daily energy intake in 7-12-y-olds, and 28% of the daily energy intake in 2-6-y-olds. In all age groups, larger portion sizes of pizza coincided with higher energy intakes at eating occasions during which pizzas were consumed. In 7-12- and 13-18-y-olds, higher energy intakes at meals coincided with larger portion sizes of SSBs, French fries, or salty snacks. In all age groups, nonsignificant larger portions of Mexican fast foods were related to higher energy intakes at meals. Adolescent boys consumed larger portion sizes of the selected foods and had higher energy intakes at meals for all periods than did girls (P < 0.01). The percentage of kilocalories from pizza within a meal increased more sharply in non-Hispanic African Americans, in Hispanics, and in the group with a low household education than in the other groups.Conclusions: Adolescents are more susceptible to increased portion sizing than are younger children. The group of non-Hispanic African Americans and Hispanics and individuals with a lower education represents key concerns for public health policies. Am J Clin Nutr 2011;94:1324-32.
