What are the four major components of a nutrition assessment (ABCD)?

• A. Anthropometric data, Biochemical data, Clinical data, Dietary data
• B. Anthropometric data, Biochemical data, Dietary data, Clinical data
• C. Biochemical data, Anthropometric data, Clinical data, Dietary data
• D. Dietary data, Anthropometric data, Clinical data, Biochemical data

Answer: (D)

These four areas work together to give a complete picture of a person’s nutritional status. Dietary data looks at what the person eats and drinks, how much, and how often, to identify gaps or excesses in nutrient intake. Anthropometric data involves physical measurements such as weight, height, body mass index, and changes in body composition that reveal energy balance and tissue depletion or gain.

Clinical data involves the medical history, symptoms, signs, and functional status that point to nutritional problems or conditions affecting nutrition, such as chronic illness, dental issues, or gastrointestinal problems. Biochemical data includes laboratory values that reflect nutrient status and metabolic processes, like protein markers, micronutrient levels, and glucose or electrolyte measurements.

Together these four domains—dietary intake, physical measurements, clinical health information, and laboratory data—provide a holistic view that helps identify malnutrition, understand its causes, and guide appropriate care. The arrangement in this question lists all four components, which is still correct because the ABCD framework is about these four areas, just in a different order.
