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.
Many previous studies applied a similar strategy (ie, without using the reduced muscle
mass criterion) to determine GLIM-defined malnutrition.

,4
According to a recent scoping review of the GLIM, approximately 25% (19/79) of previous
studies did not use the reduced muscle mass criterion.

Although this strategy might theoretically induce the risk of misclassifying malnutrition,
4
it may also increase the feasibility of GLIM-defined malnutrition as no device is
needed to measure muscle mass.To read this article in full you will need to make a payment

- PreviewIn 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.
