Abstract
BACKGROUND: There are few systematic studies on the prevalence of sarcopenia using the new diagnostic criteria in different geriatric care settings. OBJECTIVE: To estimate the prevalence of sarcopenia, using the European Working Group on Sarcopenia in Older People (EWGSOP) criteria in older subjects living in nursing homes and in those who attend geriatric outpatient clinics. MATERIAL AND METHODS: A single country multicentre study in two samples of older subjects: patients cared for in outpatient geriatric clinics, and individuals living in nursing homes. Data collected will include demographic variables, medical history, medication, geriatric syndromes, functional status (assessment of basic and instrumental activities of daily living), mobility, cognitive status, comorbidity, quality of life, nutritional status, and laboratory parameters. For the diagnosis of sarcopenia, 4m walking speed, handgrip strength, and body composition measured by bioelectrical impedance analysis will be assessed. RESULTS: Using the EWGSOP algorithm, the prevalence of sarcopenia in an elderly Spanish population will be estimated. In addition, concordance and correlation between the three parameters included in the definition (muscle mass, muscle strength, and physical performance) will be analysed, using the different existing cut-off points, and examining the diagnostic accuracy of each. Finally, demographic, anthropometric and functional data that define subjects with sarcopenia will be investigated. CONCLUSIONS: The ELLI study should improve knowledge on the prevalence and characteristics of sarcopenia in older people in our population.
