User’s Guide for Analysis of Usual Intakes

This document describes the MIXTRAN, DISTRIB, and INDIVINT SAS macros that implement a statistical method for estimating usual dietary intakes of a single dietary component, whether consumed daily or episodically. This method can be used for a variety of applications, including: estimating the distribution of usual food or nutrient intake for a population or subpopulation; predicting individual food or nutrient intake for use in a disease model; and evaluating the effects of individual covariates on food or nutrient consumption.
