A conceptual framework for individual nutrition
1981
Nestor, Joanne P.
A conceptual framework is needed for the complex interrelationships existing for factors that determine an individual's nutritional status, in order to compare and evaluate nutrition education studies and programs. A model is described which relates secondary (family, community, public, private, and medical sectors) and primary (nutrition knowledge, attitudes, beliefs, and food needs, economics, and eating options) influences on dietary habits such as food-related behavior, dietary intake, and nutrient uptake, and nutritional status. Anthropometric and biochemical status, and general vitality are outcome indicators that measure nutrient uptake and nutritional status. The factors discussed are closely related to school activities and school-based nutrition education. Each of the component stages of the model are discussed individually, as is their interaction.
