Screening Performance of Anthropometric Indices and Determination of Optimal Cut-Off Values for Identifying Low Muscle Strength in Hospitalized Geriatric Patients
Cross-sectional study evaluates anthropometric measurements for identifying low muscle strength in hospitalized geriatric patients, suggesting practical screening options.
Key Points
This study aims to identify effective anthropometric indices for screening low muscle strength in hospitalized geriatric patients and establish preliminary cut-off values.
Cross-sectional study with 390 hospitalized patients aged ≥ 60 years; median age 77.00 years.
Measured anthropometric dimensions and handgrip strength; assessed low muscle strength using EWGSOP2 criteria.
Used logistic regression and ROC curve analysis to evaluate screening performance of anthropometric measures.
17.2% of participants had low muscle strength, linked with older age, lower body weight, BMI, fat-free mass, and smaller circumferences.
Optimal cut-off values identified: arm 26.5 cm and calf 31.5 cm for women, arm 29.5 cm and calf 33 cm for men, with moderate screening performance (AUC 0.63–0.78).
Higher arm and calf circumferences associated with a significantly lower risk of low muscle strength (OR for men; arm 0.793, calf 0.769; p < 0.05).
