先验饮食指数提供了一种标准化、可重复的方法来评估不同人群对饮食建议的遵守情况。现有的基于营养的指数是为了反映食物/饮料的摄入量而制定的；然而，考虑到膳食补充剂 (DS) 的广泛使用及其对使用者营养摄入的潜在巨大贡献，不考虑 DS 的暴露分类是不完整的。本文的目的是回顾现有的基于营养的指数，并描述总营养指数 (TNI) 的发展，该指数的开发是为了获取美国人口中所有摄入不足的微量营养素来源的通常摄入量。 TNI 根据《美国人膳食指南》确定的八种摄入不足的微量营养素的推荐营养标准来评估美国成年人的总营养素摄入量：钙、镁、钾、胆碱和维生素 A、C、D、E。TNI 的评分范围为 0 到 100（截断为 100）。根据 NHANES 2011-2014 年饮食数据，美国成年人（≥19 岁；n = 9,954）的平均 TNI 得分为 75.4；忽略 DS 贡献的指数平均得分仅为 69.0（t 检验；p<0.001）。 TNI 通过纳入所有来源的营养摄入量来扩展现有的饮食质量衡量标准，其开发目的是为了研究、监测和政策目的。
A priori dietary indices provide a standardized, reproducible way to evaluate adherence to dietary recommendations across different populations. Existing nutrient-based indices were developed to reflect food/beverage intake; however, given the high prevalence of dietary supplement (DS) use and its potentially large contribution to nutrient intakes for those that use them, exposure classification without accounting for DS is incomplete. The purpose of this article is to review existing nutrient-based indices and describe the development of the Total Nutrient Index (TNI), an index developed to capture usual intakes from all sources of under-consumed micronutrients among the U.S. population. The TNI assesses U.S. adults’ total nutrient intakes relative to recommended nutrient standards for eight under-consumed micronutrients identified by the Dietary Guidelines for Americans: calcium, magnesium, potassium, choline, and vitamins A, C, D, E. The TNI is scored from 0 to 100 (truncated at 100). The mean TNI score of U.S. adults (≥19y; n = 9,954) based on dietary data from NHANES 2011–2014, was 75.4; the mean score for the index ignoring DS contributions was only 69.0 (t-test; p<0.001). The TNI extends existing measures of diet quality by including nutrient intakes from all sources and was developed for research, monitoring, and policy purposes.
