Standardizing Criteria for Age-Related Muscle Loss
The term “sarcopenia”, from the Greek “sarco” meaning flesh and “penia” meaning deficiency, is most often used to describe age-related loss in muscle mass and strength, and it is commonly considered analogous to osteoporosis. Yet unlike osteoporosis, which can be diagnosed based on widely accepted clinical criteria, sarcopenia is not recognized as a clinical condition even though it can impair physical function and contribute to disability, falls, and hospitalizations.
A new review published in April 2015 in Journal of Bone and Mineral Research addresses this concern and points to efforts aimed at developing and refining sarcopenia criteria.
A release from the publisher quotes lead author Dr. Robert McLean as saying, “For over 20 years, the lack of a consensus definition for sarcopenia has been a significant barrier for the development of interventions aimed at preserving or improving muscle mass and strength in older adults. The recent and ongoing efforts of the Foundation for the National Institutes of Health Sarcopenia Project are a major advancement toward closing this important gap.”
