Question

Which parameter conclusively rules out malnutrition ?

• A. Edema
• B. Lean body mass
• C. Skinfold thickness
• D. Normal ECF volume

Answer 1

The Correct Option is B

In the context of ruling out malnutrition, different parameters are assessed to determine the nutritional status of an individual. Let's examine each option:

1. Edema: Edema refers to swelling caused by excess fluid trapped in the body's tissues. It can occur due to various reasons including malnutrition, particularly protein energy malnutrition. Hence, it does not conclusively rule out malnutrition.

2. Lean body mass: This parameter refers to the mass of the body minus the fat. An adequate lean body mass is a strong indicator of good nutritional status. If lean body mass is preserved at normal levels, it conclusively indicates the absence of malnutrition, making it the most reliable indicator to rule out malnutrition.

3. Skinfold thickness: This measures the subcutaneous fat layer and helps estimate body fat percentage. While it is related to nutritional status, it alone cannot conclusively rule out malnutrition.

4. Normal ECF volume: Extracellular fluid (ECF) volume refers to the fluid outside the body's cells. Normal ECF volume can be maintained despite malnutrition through fluid retention, and thus, it is not a conclusive parameter to rule out malnutrition.

In conclusion, Lean body mass is the parameter that conclusively rules out malnutrition because it directly reflects body protein reserves and overall nutrition status.
