title: Dietary survey of low-income, rural families in Iowa and North Carolina. I. Research procedures.
abstract: Methods used in assessing the dietary intake of selected low-income, rural families are described. The sample consisted of 668 families randomly selected from predetermined locations in Iowa and North Carolina. A 24-hr. recall method supplemented with food models was used in gathering data on family food intake. The nutritional "adequacy" of the family diets was then evaluated according to family composition and the 1968 Recommended Dietary Allowances. The adequacy of individual nutrients was also evaluated by the same criteria. Nutrients studied included: protein, calcium, iron, vitamin A, ascorbic acid, thiamin, and riboflavin. The selection of the method in relation to opinions of previous investigators is discussed.
