Which statement about the weighting in the Subjective Global Assessment is true?

• A. The SGA weighting is subjective to reflect clinical judgment
• B. The SGA uses objective scoring
• C. The SGA relies on BMI only
• D. The SGA excludes dietary intake

Answer: (A)

Weighting in the Subjective Global Assessment is subjective to reflect clinical judgment. The SGA uses a clinician’s overall impression based on multiple domains—weight change, dietary intake, gastrointestinal symptoms, functional capacity, and physical examination findings like muscle wasting and edema—to categorize nutritional status. There isn’t a fixed objective scoring system with numeric weights; the clinician weighs these factors together to determine whether the patient is well nourished, moderately malnourished, or severely malnourished. This approach contrasts with relying on a single metric like BMI, and it includes dietary intake as part of the assessment rather than excluding it.
