There is an accumulating evidence of the overlap and frequent co-occurrence of twasting conditions in older adults. Those conditions include malnutrition, sarcopenia, and cachexia, Therefore , a tool capable of simultaneously screening for all three conditions is imperative. In this study, we developed and validated a new tool for the simultaneous screening of muscle wasting diseases in older adults. The diagnostic accuracy of the new tool was compared to other validated screening tools including the Mini Nutritional Assessment-Short Form (MNA-SF), the Short Nutritional Assessment Questionnaire (SNAQ), and the Simple Questionnaire to Rapidly Diagnose Sarcopenia (SARC-F).
