Prevalência da sarcopenia, baseada no EWGSOP2, utilizando diferentes métodos de avaliação em idosos residentes da comunidade

Abstract

Introduction: As the world population ages, one of the important challenges for the health area is to intervene in the decline of the musculoskeletal system. This decline consists primarily of reduced muscle mass and function, which is called sarcopenia and is associated with adverse health outcomes. The prevalence of sarcopenia varies greatly, as these depend on the characteristics of the studied population, the definitions found in the literature. Different reference values have a critical impact on the epidemiology of sarcopenia. Objective: To verify the prevalence of sarcopenia using different forms of assessment proposed by the EWGSOP2. Methods: 778 community-dwelling elderly people living in a city in Rio Grande do Norte, Brazil were evaluated. Cut-off points were defined for the variables used to screen for sarcopenia (grip strength, sit-stand test, skeletal muscle mass, gait speed, and SPPB) and the prevalence of sarcopenia components was found according to categorization by age group. Results: Comparing the proportions between the forms of assessment, a greater proportion of sarcopenia was observed in the methods that used the MME without adjustment for height and in the age group over 75 years, both for handgrip (B, 15.6%) and for the sit-to-stand test (D, 11.9%). Conclusion: The prevalence of sarcopenia varies according to the methods used, where it is possible to do the screening through the grip strength as well as the sit-up test and both are more sensitive when associated with muscle mass without height adjustments
