美国农业部 (USDA) 2005 年健康饮食指数 (HEI-2005) 是量化和评估美国人口饮食质量的工具。它由 12 个组成部分组成，以食物组或营养素与能量摄入的比率表示。这些成分的评分范围为 0 到 M，其中 M 为 5、10 或 20。理想情况下，HEI-2005 是根据个人通常的饮食摄入量计算的。通过 24 小时回忆收集的摄入量数据通常只能获得每个人一天的数据。在本文中，我们研究了当可以获得人群样本中的一天饮食信息时，如何最好地估计人群的平均通常 HEI-2005 成分和总分。考虑三种方法：个体得分平均值、个体比率平均值得分以及总食物组或营养素摄入量与总能量摄入量之比的得分，我们称之为总体比率。我们通过计算机模拟研究哪种方法偏差最小。这些模拟基于参与“美国餐桌饮食研究”的 738 名女性报告的摄入量分布的统计模型。结果表明总体人口比例评分是首选方法。因此，我们建议使用这种方法评估和监测美国人口的饮食质量。
The U.S. Department of Agriculture’s (USDA) Healthy Eating Index-2005 (HEI-2005) is a tool to quantify and evaluate the quality of diet consumed by the US population. It comprises 12 components, expressed as ratios of a food group or nutrient to energy intake. The components are scored on a scale from 0 to M, where M is 5, 10 or 20. Ideally the HEI-2005 is calculated on the basis of the usual dietary intake of an individual. Intake data, collected via a 24-hour recall, are often available for only one day on each individual. In this paper, we examine how best to estimate a population’s mean usual HEI-2005 component and total scores when one day of dietary information is available for a sample of individuals from the population. Three methods are considered: the mean of individual scores, the score of the mean of individual ratios, and the score of the ratio of total food group or nutrient intake to total energy intake, which we call the population ratio. We investigate via computer simulation which method is the least biased. The simulations are based on statistical modeling of the distributions of intakes reported by 738 women participating in the Eating at America’s Table Study. The results show that overall the score of the population ratio is the preferred method. We therefore recommend that the quality of the US population’s diet be assessed and monitored using this method.
