An article in the March issue of JAMDA describes the 2019 Asian Consensus Update on Sarcopenia, which retains muscle mass criteria, divides diagnoses into community or hospital settings, and defines “possible sarcopenia” to identify at-risk people in the community.

In Asian Working Group for Sarcopenia: 2019 Consensus Update on Sarcopenia Diagnosis and Treatment, the authors observed that the 2019 document includes the same definition of sarcopenia detailed in the 2014 consensus: an age-related loss of muscle mass, plus low muscle strength, and/or low physical performance. However, the latest consensus has revised the diagnostic algorithm, protocols, and some criteria. It also proposes separate algorithms for community versus hospital settings to facilitate earlier identification of those individuals at risk for sarcopenia.

Although skeletal muscle strength and mass are both considered fundamental to a definitive clinical diagnosis of sarcopenia, the authors observed that the 2019 consensus “introduces ‘possible sarcopenia,’ defined by either low muscle strength or low physical performance only, specifically for use in primary health care or community-based health promotion, to enable earlier lifestyle interventions.” They further observed that while defining sarcopenia by Body Mass Index-adjusted muscle mass instead of height-adjusted muscle mass may predict adverse outcomes better, “more evidence is needed before changing current recommendations.”

Lifestyle interventions, the authors noted, prevail as treatment mainstays. However, they said, “Further research is needed to investigate potential long-term benefits of lifestyle interventions, nutritional supplements, or pharmacotherapy for sarcopenia in Asians.”
