Estimate Population Mean Intakes
Purpose
One of the most frequently cited measures in dietary assessment is mean intake. Because NHANES is a sample of the US population, weighted sample means are estimates of the population means. This module covers the estimation of mean food intakes and the estimation of mean nutrient intakes.
Task 1: Estimate Mean Food Intakes
This task reviews the key concepts related to measurement error associated with mean food intakes and the need to group foods for analysis. It also provides instructions on deriving means and standard errors, using intake of milk consumed as a beverage and total milk and milk products as examples.
