What does weight for length represent in the Waterlow criteria?

• A. Wasting caused by illness
• B. Wasting caused by hypoaluminemia
• C. Wasting due to chronic malnutrition
• D. Wasting due to acute malnutrition

Answer: (D)

Weight-for-length reflects acute malnutrition because it shows how a child’s current weight compares to what would be expected for their length, capturing recent weight loss or failure to gain weight. Short-term changes in intake or illness quickly affect weight, so a low weight-for-length indicates wasting from acute malnutrition. In the Waterlow framework, wasting is the sign of acute malnutrition, while stunting is indicated by low height-for-age (longer-term malnutrition), and underweight is low weight-for-age (a combination that can reflect either acute or chronic factors).
