饮食监测的一个长期目标是估计摄入量高于或低于目标（例如推荐摄入量）的人口比例。然而，到目前为止，还缺乏评估食物摄入量与建议是否一致的统计方法。这项研究的目的是展示美国国家癌症研究所估算日常食物摄入量分布的方法，并确定不符合联邦饮食建议的美国人口比例。数据取自 2001-2004 年 NHANES，涉及 16,338 名 2 岁及以上的人。使用 MyPyramid 等效数据库将 24 小时召回报告的食品数量转换为各种食品组的数量。对通常的饮食摄入分布进行了建模，考虑了序列效应；周末/工作日效应、性别、年龄、贫困收入比和种族/民族。除全谷物、肉类和豆类外，大多数人并未达到所有营养丰富食物类别的建议。与此同时，从固体脂肪、添加糖和酒精饮料（“空卡路里”）中过度消耗能量的现象普遍存在。超过 80% 的年龄 >= 71 岁的人和超过 90% 的所有其他性别年龄组的空卡路里摄入量超过了可自由支配的卡路里限额。总之，几乎所有美国人的饮食习惯都不符合建议。这些发现为一个国家饮食危机中正在出现的相当令人不安的景象增添了另一幅景象。 J.努特尔。 140：1832-1838，2010。
A longstanding goal of dietary surveillance has been to estimate the proportion of the population with intakes above or below a target, such as a recommended level of intake. However, until now, statistical methods for assessing the alignment of food intakes with recommendations have been lacking. The purposes of this study were to demonstrate the National Cancer Institute's method of estimating the distribution of usual intake of foods and determine the proportion of the U.S. population who does not meet federal dietary recommendations. Data were obtained from the 2001-2004 NHANES for 16,338 persons, aged 2 y and older. Quantities of foods reported on 24-h recalls were translated into amounts of various food groups using the MyPyramid Equivalents Database. Usual dietary intake distributions were modeled, accounting for sequence effect; weekend/weekday effect, sex, age, poverty income ratio, and race/ethnicity. The majority of the population did not meet recommendations for all of the nutrient-rich food groups, except total grains and meat and beans. Concomitantly, overconsumption of energy from solid fats, added sugars, and alcoholic beverages ("empty calories") was ubiquitous. Over 80% of persons age >= 71 y and over 90% of all other sex-age groups had intakes of empty calories that exceeded the discretionary calorie allowances. In conclusion, nearly the entire U.S. population consumes a diet that is not on par with recommendations. These findings add another piece to the rather disturbing picture that is emerging of a nation's diet in crisis. J. Nutr. 140: 1832-1838, 2010.
