mid-arm muscle area

mid-arm muscle area

A derived value for estimating lean body mass as a function of skeletal muscle; ±30% below a standardised value (52 to 55 for males; 31 to 35 for females) from the Health and Nutritional Examination Surveys (HANES) data indicates a depletion of lean body mass (i.e., malnutrition).

mid-arm muscle area

A derived value for estimating lean body mass as a function of skeletal muscle; ≥ 30% below a standardized value–52–55 for ♂; 31–35 for ♀–Health & Nutritional Examination Surveys–HANES data indicates a depletion of lean body mass, ie malnutrition.; Cf Triceps skin fold.
