Sarcopenia

Abstract

Introducción: La sarcopenia aumenta el riesgo de caídas y fracturas, además de relacionarse con diversas enfermedades y aumento de la mortalidad. Distintos grupos de investigación proponen diferentes definiciones para el diagnóstico de sarcopenia, que incluyen la medición de la masa muscular por DEXA y la valoración de la fuerza de prensión palmar a través de un dinamómetro de mano. Sin embargo, estos 2 instrumentos no están habitualmente disponibles en los consultorios médicos. Objetivos: Determinar la utilidad diagnóstica de 2 pruebas de rendimiento físico: velocidad de marcha e incorporarse de una silla, como herramientas para la detección de pacientes con probable sarcopenia. Metodología: Se incluyeron 706 mujeres, entre 50 y 85 años, a las que se realizó las pruebas funcionales y DXA (n=376) para medir la masa muscular. Resultados: El 26,1% registró una velocidad de marcha disminuida mientras que el 55,3% presentó alteración en la realización de la prueba de incorporarse de una silla. La prevalencia de sarcopenia varió desde un 4,5% hasta un 35% según los criterios utilizados. Ambas pruebas presentaron un alto valor predictivo negativo (>70%) para el diagnóstico de sarcopenia, mientras que la prueba de incorporarse de una silla mostró además, una alta sensibilidad (> 66%) para dicho diagnóstico. Conclusión: La implementación en el consultorio de estas pruebas sencillas y sin costo, simplificaría la detección de pacientes con probable sarcopenia.
