In a recent JAMDA article, Xie et al

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. In contrast to SMI,
skeletal muscle radiodensity and handgrip strength, IMAT was not associated with malnutrition.To read this article in full you will need to make a payment

- PreviewWe thank Drs Tasci and Naharci for their interest in our recent manuscript.1 First, according to the Global Leadership Initiative on Malnutrition (GLIM) consensus, the diagnosis of malnutrition should include at least 1 phenotypic criterion (either weight loss, low body mass index, or “reduced muscle mass”) and 1 etiologic criterion (either reduced food intake, assimilation disease burden, or inflammatory condition).2 In our study, we defined malnutrition based on this algorithm. However, we did not include reduced muscle mass as a phenotypic criterion to define malnutrition because one of our aims was to explore the association between malnutrition and muscle mass.
