In a cross-sectional study of 149 adults with prediabetes, researchers found that relative handgrip strength, calculated as grip strength divided by body mass index, demonstrated strong discriminatory ability (area under the curve 0.867) for identifying probable sarcopenia defined by low absolute handgrip strength. Relative handgrip strength was significantly associated with adverse metabolic parameters and outperformed absolute grip strength in detecting functional muscle impairment across varying body compositions, supporting its role as a practical adjunct screening tool.
