Prevalencia de sarcopenia determinada por diferentes criterios diagnósticos en ancianos hospitalizados

espanolFundamentos: La sarcopenia es un sindrome geriatrico caracterizado por la perdida progresiva de masa muscular esqueletica, disminucion de fuerza y rendimiento fisico. El objetivo de este estudio fue conocer la prevalencia de la sarcopenia en la poblacion anciana mayor o igual a 65 anos en el Hospital Central de la Defensa Gomez Ulla (Madrid), segun tres criterios diagnosticos. Metodos: Se realizo un estudio transversal entre 295 personas con edad mayor o igual a 65 anos a fecha de inicio del estudio, ingresados en el citado hospital entre el 1 de marzo y el 30 de septiembre de 2018. La sarcopenia se definio en funcion de la masa muscular, la fuerza muscular y la funcionalidad, de acuerdo al criterio EWGSOP, EWGSOP2 y SARC-F. Se compararon usando la prueba de McNemar y el Indice Kappa. Resultados: La prevalencia de sarcopenia segun el criterio EWGSOP fue del 43,7% (IC 95%; 38%-49,4%), segun EWGSOP2 del 28,5% (23,3%-33,7%) y segun el criterio SARC-F del 37,6% (32%-43,1%), siendo mayor en hombres que en mujeres con diferencia estadisticamente significativa (p Conclusiones: La prevalencia de sarcopenia es diferente dependiendo del criterio de medida. No es posible intercambiar los criterios EWGSOP, EWGSOP2 y el cuestionario SARC-F para minimizar recursos. EnglishBackground: Sarcopenia is a geriatric syndrome characterised by the progressive loss of skeletal muscle mass, muscular strength, and physical performance; it carries the risk of physical incapacity and reduced quality of life. This work reported the prevalence of sarcopenia in people aged ≥65 years, all in-patients at the Hospital Central de la Defensa Gomez Ulla, as determined by three sets of diagnostic criteria. The suitability of the indistinct use of these criteria sets was discussed. Methods: This was a cross sectional study. Sarcopenia was diagnosed depending on muscle mass, strength and functionality according to the European Working Group on Sarcopenia in Older People (EWGSOP), EWSOP2 and SARCF criteria. This study involved 295 people, all aged ≥65 years, and all of whom had been admitted to the above hospital between 1st March and 30th September 2018. Sampling was consecutive and performed at the internal medicine ward. Results: The overall prevalence of sarcopenia was 43.7% [95%CI 38-49.4%] according to the EWGSOP criteria, 28.5% [23.3-33.7%] according to EWGSOP2, and 37.6% [32-43.1%] according to SARCF. The EWGSOP criteria showed sarcopenia to be significantly more common among men than women (p Conclusions: The prevalence of sarcopenia recorded differed depending on the set of criteria used; they cannot, therefore, be used indistinctly for the diagnosis of this condition. Rather, given the results obtained, it would seem reasonable, in Europe, to continue using the EGSWOP criteria while research continues in this area.
