{Abstract}: BACKGROUND: The main aim of this study is to assess the prevalence of sarcopenia, according to the criteria of the European Working Group on Sarcopenia in Older People, in men and women living in Spanish nursing homes.
METHODS: Multi-centre study was conducted on ambulatory persons over 69 years old living in nursing homes. Body composition was assessed using bioimpedance analysis, grip strength with a Jamar dynamometer, and gait speed using the 4 metre walk test. Sarcopenia was assessed using the European Working Group on Sarcopenia in Older People criteria (gait speed<0.8m/s; grip strength<30kg in men or 20kg in women, and muscle mass index <8.31kg/m(2) in men or<6.68kg/m(2) in women).
RESULTS: The study included 276 subjects with a median age 87.2 years, and with 69% women. Sarcopenia was demonstrated in 37% (15% men, 46% women), 37% had low muscle mass, 86% low gait speed, and 95% low grip strength. Prevalence of sarcopenia increased with advancing age. Both weakness and low gait speed was observed in 90% of individuals with sarcopenia, with 39% of the total having low gait speed, and 38% with weakness.
CONCLUSIONS: Sarcopenia is a frequent condition in older persons living in nursing homes, especially among women. Most of the cases are severe, with both low muscle strength and physical performance. Although muscle function is altered in 9 out 10 participants, most of them have preserved muscle mass.
