Handgrip Strength Signals Malnutrition Risk.
In 2025, Vânia Aparecida Leandro-Merhi and a team from Pontifical Catholic University of Campinas studied 211 hospitalized adults in Brazil’s public health system. They used the Global Leadership Initiative on Malnutrition (GLIM) criteria and handgrip strength (HGS) to spot nutritional risks, comparing them to standard tools like Nutritional Risk Screening-2002, measuring muscle strength and body composition.
