Comment on “Malnutrition in Relation to Muscle Mass, Muscle Quality, and Muscle Strength in Hospitalized Older Adults”

In a recent JAMDA article, Xie et al1 reported that patients with a malnutrition diagnosis assessed by the Global Leadership Initiative on Malnutrition (GLIM) had significantly lower skeletal muscle radiodensity, an indicator of muscle quality, and lower handgrip strength in both genders. Additionally, women, but not men, with a malnutrition diagnosis had significantly higher intermuscular adipose tissue (IMAT), another indicator of muscle quality, than women with normal nutrition; moreover, in contrast to women, men with malnutrition had significantly lower skeletal muscle index (SMI), an indicator of muscle mass.
