Sarcopenia is an age-related geriatric syndrome characterized by decreased muscle mass, reduced muscle strength, and/or impaired physical function. It is closely associated with adverse health outcomes such as frailty, falls, fractures, disability, and even death. In community-dwelling populations, sarcopenia often presents in early or subclinical stages, making it easy to overlook and resulting in missed opportunities for timely intervention. Standardized screening for sarcopenia among older adults in the community is of great significance for early detection, targeted intervention, delaying functional decline, preventing and mitigating disability, reducing healthcare costs, and responding to the challenges of an aging society. However, there is currently a lack of evidence-based expert consensus on community-based sarcopenia screening for older adults in China. To bridge the gap, the China Rehabilitation Science Institute, Community-Based Rehabilitation Committee of the China Association of Rehabilitation of Disabled Persons, Geriatric Rehabilitation Committee of Chinese Association of Geriatric Research, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences) /Southern Medical University and the Guangzhou Association of Rehabilitation Medicine led the development of this consensus. Using the Delphi method to form a list of key questions and recommendations, the GRADE system to assess the quality of evidence and strength of recommendations, and the RIGHT checklist to standardize reporting, a total of 14 evidence-based recommendations were established. This expert consensus on community-based sarcopenia screening in older adults provides a scientific and feasible screening pathway, supports the construction of an early detection, early identification, and early intervention system for sarcopenia prevention and control in the community, and ultimately aims to improve the health and quality of life of the older population.
