Mid-arm muscle circumference and hand grip strength are sensitive markers for what?

• A. Liver enzyme depletion
• B. Body cell mass depletion
• C. Bone mineral decrease
• D. Kidney function decline

Answer: (B)

Mid-arm muscle circumference and hand grip strength reflect the amount and function of lean body tissue, particularly lean muscle mass. They are sensitive indicators of body cell mass depletion because muscle mass and its strength decrease early when protein and energy intake are insufficient or during chronic illness, often before changes in overall weight become apparent. Grip strength, in particular, correlates with nutritional status and functional capacity, signaling problems with protein-energy reserves. These measures are not direct markers of liver enzymes, bone mineral density, or kidney function, which involve different biological processes and tests. Using them helps detect early malnutrition and guide targeted nutrition interventions to preserve or restore lean body mass.
