评估整个生命周期饮食多维成分的指数在描述饮食质量方面很有用。本研究的目的是使用健康饮食指数-2005，一个衡量饮食质量的标准，符合2005年美国人饮食指南，通过不同的社会人口特征来描述美国人的饮食质量，以提供有关饮食需要改善的见解。2005年健康饮食指数的得分是使用2003-2004年国家健康和营养检查调查参与者提供的1天饮食摄入数据估计的。平均每日食物和营养素摄入量（以每1，000卡路里表示）是使用人口比率法估计的，并与反映2005年美国人膳食指南的标准进行比较。参与者包括3，286名儿童（2至17岁）、3，690名青少年和中年人（18至64岁）以及1，296名老年人（65岁以上）。结果以最高分数的百分比报告，并进行显著性差异（P
An index that assesses the multidimensional components of the diet across the lifecycle is useful in describing diet quality. The purpose of this study was to use the Healthy Eating Index-2005, a measure of diet quality in terms of conformance to the 2005 Dietary Guidelines for Americans, to describe the diet quality of Americans by varying sociodemographic characteristics in order to provide insight as to where diets need to improve. The Healthy Eating Index-2005 scores were estimated using 1 day of dietary intake data provided by participants in the 2003-2004 National Health and Nutrition Examination Survey. Mean daily intakes of foods and nutrients, expressed per 1,000 kilocalories, were estimated using the population ratio method and compared with standards that reflect the 2005 Dietary Guidelines for Americans. Participants included 3,286 children (2 to 17 years), 3,690 young and middle-aged adults (18 to 64 years), and 1,296 older adults (65+ years). Results are reported as percentages of maximum scores and tested for significant differences (P
