Hospital-associated sarcopenia, acute sarcopenia, and iatrogenic sarcopenia: Prevention of sarcopenia during hospitalization

Abstract

Sarcopenia can be classified as age-, activity-, nutrition-, and disease-related. Hospital-associated sarcopenia, acute sarcopenia, and iatrogenic sarcopenia are activity-, nutrition-, and disease-related, not age-related. There is considerable overlap between hospital-associated sarcopenia and acute sarcopenia; however, they are distinct concepts. Some causes of hospital-associated sarcopenia and acute sarcopenia are iatrogenic.
