Analyses of the 1985 Continuing Survey of Food Intakes by Individuals. Volume 1.Estimating Usual Dietary Intake, Assessing Dietary Adequacy, and Estimating Program Effects: Applications of Three Advanced Methodologies Using FNS's Four-Day Analysis File

摘要

This report presents findings from a study of the feasibility of using threeadvanced statistical methodologies to analyze data from food consumption surveys. The first methodology generates improved estimates of usual dietary intake by individuals on the basis of a small number of days of survey data. The second methodology makes use of data on nutritional requirements, as well as data on dietary intake, to estimate the incidence of dietary inadequacy in a population. The third methodology generates improved estimates of the effects of any two assistance programs on dietary quality and household food expenditures when decisions to participate in the programs are made jointly.
