Which option lists the four main components used to assess nutritional status?

• A. Anthropometrical, Biochemical, Clinical, Diet
• B. Diet Records
• C. Dietary Reference Intake
• D. Food Frequency Questionnaire

Answer: (A)

Nutritional status is best understood through a four-part framework that covers body size and composition, laboratory indicators, clinical signs, and dietary intake. Anthropometrical measurements (like height, weight, BMI, waist circumference and skinfolds) track growth and body composition. Biochemical tests (in blood or urine) reveal nutrient levels and function that may not be evident from appearance alone. Clinical evaluation looks for physical signs of deficiency or excess and considers medical history that can influence nutrition. Diet assessment examines usual intake and patterns to understand what nutrients are being consumed.

These four areas—anthropometrical, biochemical, clinical, and diet—form the comprehensive assessment. Diet Records are one way to evaluate intake, but they are a method within the diet component, not the whole framework. Dietary Reference Intake is a set of nutrient recommendations, not an assessment approach. A Food Frequency Questionnaire is a single dietary assessment tool, not the complete four-part structure.
