Which parameter is used to classify malnutrition into four levels in the Waterlow criteria?

• A. Degree of undernutrition
• B. Body mass index
• C. Serum albumin
• D. Blood pressure

Answer: (A)

Waterlow classifies malnutrition by how severely undernourished a person is, using anthropometric measurements to gauge the degree of undernutrition. The four levels come from comparing weight-for-height, height-for-age, and weight-for-age (with the presence of edema considered) to reference standards. This approach focuses on the extent of undernutrition rather than static lab values or vital signs, which is why the degree of undernutrition best explains the four-level classification.
