III

Application of DRIs for Group Diet Assessment

The focus of Part III is on applying the appropriate DRIs for dietary assessment of groups.

Chapter 4 provides the statistical basis for the use of the Estimated Average Requirement (EAR) in assessing nutrient adequacy of groups. The chapter begins with a basic discussion of the concept of assessing the prevalence of inadequate nutrient intakes and then develops the statistical approaches for estimating this prevalence. Assumptions required for the use of the statistical approaches are discussed, as is the need for adjusting intake distributions.

Using the Adequate Intake (AI) for group-level assessment of nutrient adequacy is discussed in Chapter 5. Guidance on the extent to which the Tolerable Upper Intake Level (UL) can be used to estimate the prevalence of risk of adverse effects in groups is provided in Chapter 6.

Specific guidance with examples on appropriate applications of the DRIs for group assessment purposes is provided in Chapter 7. In this chapter, the methodological approaches described in Chapter 4, Chapter 5, and Chapter 6 are applied to some of the specific uses of dietary reference standards reported in Chapter 2. Three specific applications are presented and discussed.

Since 1994 the Institute of Medicine's Food and Nutrition Board has been involved in developing an expanded approach to developing dietary reference standards. This approach, the Dietary Reference Intakes (DRIs), provides a set of four nutrient-based reference values designed to replace the Recommended Dietary Allowances (RDAs) in the United States and the Recommended Nutrient Intakes (RNIs) in Canada. These reference values include Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL). To date, several volumes in this series have been published.

This new book, Applications in Dietary Assessment, provides guidance to nutrition and health research professionals on the application of the new DRIs. It represents both a "how to" manual and a "why" manual. Specific examples of both appropriate and inappropriate uses of the DRIs in assessing nutrient adequacy of groups and of individuals are provided, along with detailed statistical approaches for the methods described. In addition, a clear distinction is made between assessing individuals and assessing groups as the approaches used are quite different. Applications in Dietary Assessment will be an essential companion to any-or all-of the DRI volumes.
