Abstract
Objective: The aim of this study was to compare the prevalence of sarcopenia among frail nursing home residents, diagnosed according to 10 different operational definitions.
Methods: This is an analysis of data collected at baseline in the SENIOR (Sample of Elderly Nursing home
Individuals: an Observational Research) cohort. All subjects received a diagnosis of sarcopenia, based on the definition proposed by the European Working Group on Sarcopenia in Older People (EWGSOP). The frailty evaluation was based on 10 different operational definitions and the prevalence of sarcopenia was assessed for each of them.
Results: A total of 662 subjects from 28 nursing homes aged 83.2±8.99 years (73.1% of women) were included in this study. In this populat ion, prevalence of sarcopenia was 38.1% and prevalence of frailty varied from 1.70% (Frailty Index) to 76.3% (Groningen Frailty Indicator and Sega Grid), depending on the definition
ed. When regarding the prevalence of sarcopenia among frail subjects, it was ranged between 32.8% (i.e. Frail scale Status and Frailty Index) and 47% (i.e. Fried definition).
