The Nutrition Diagnosis comes from specific terminology found in eNCPT (previously the IDNT Reference Manual) .
The Nutrition Diagnosis terms are classified into three categories:
Intake: these diagnosis relate to intake and nutrition related problems (oral, enteral and parenteral nutrition). Intake diagnosis cover the areas including energy balance, fluid intake, bioactive substances and nutrient intake.
Examples: excessive energy intake, less than optimal intake of types of carbohydrate, inadequate calcium intake.
Clinical: these diagnosis include medical or physical conditions that have a nutritional impact. The clinical category covers the areas of functional changes or impairments, biochemical changes (altered ability to metabolize nutrients) and weight.
Examples: altered GI function, impaired nutrient utilization, overweight/obesity.
Behavioral-Environmental: this category covers the nutritional problems associated with nutrition knowledge and belief (including attitude), physical activity and function (e.g. ability to self care) and food access and safety).
