Resumen

Introduction: Weak grip strength, slow walking speed, changes in body composition are very common in hospitalized older adults, their presence implies alterations in mobility, longer hospital stay, risk of falls and frailty. Objective: To evaluate the association between physical performance and nutritional status in older adults hospitalized in an EsSalud hospital in Juliaca-Peru, 2023. Methods: Quantitative approach research, descriptive cross-association, cross-sectional, observational and prospective design, the sample consisted of 50 older adults hospitalized in Base Hospital III of the Juliaca EsSalud Healthcare Network. With the due consent of the patients, data was collected, nutritional assessment was carried out by taking anthropometric measurements such as weight, height and calf circumference; manual grip strength was determined using a Jamar brand dynamometer, and functional capacity was evaluated using the timed get up and walk test. Statistical analysis was performed using measures of central tendency such as median and interquartile range, and the chi-square test was applied to evaluate the relationship between variables. Results: The relationship between BMI and physical performance was not statistically significant (p=0.470). Similarly, the association between muscle mass and handgrip strength did not reach statistical significance (p=0.052). On the other hand, decreased muscle mass was significantly associated with an increased risk in the “Get Up and Walk” test (p<0.001). Conclusion: A statistically significant association was identified between muscle mass and physical performance. Older adults with decreased muscle mass showed lower physical performance, reflecting a possible relationship between muscle loss and decreased functional capacity.
