OBJECTIVES: To evaluate whether dynapenia at hospital admission predicts adverse events in older adults hospitalized for medical conditions.
DESIGN: Prospective observational cohort study.
SETTING: Hospital Cayetano Heredia, Lima, Peru.
PARTICIPANTS: 120 patients aged ≥60 years admitted for medical reasons between July and December 2024.
MEASUREMENTS: Handgrip strength was assessed within 48 h of admission using a JAMAR® dynamometer. Dynapenia was defined as <12 kg in men and <8 kg in women (sex-specific 25th percentile). Participants were followed for 30 days to identify adverse events, including mortality, delirium, readmission, healthcare-associated infections, pressure ulcers, and falls. Cox regression models estimated hazard ratios (HR).
RESULTS: Median age was 74 years; 49.2% were women. Dynapenia was present in 30% of participants. During follow-up, 45 adverse events were documented: mortality (12.5%), delirium (9.2%), readmission (5.8%), and others (7.4%). Patients with dynapenia had a higher incidence of adverse outcomes (41.7% vs. 16.7%, p < 0.05). Dynapenia was independently associated with adverse events (adjusted HR 2.32; 95% CI: 1.08-4.99). Sensitivity analyses using intrapopulation tertiles and EWGSOP2 thresholds yielded consistent associations.
CONCLUSION: Dynapenia at admission is an independent predictor of adverse events in hospitalized older adults. Handgrip strength is a simple bedside tool that may improve early risk stratification and support targeted preventive interventions.
