With the aging of the population,the morbidity of sarcopenia continues to increase.The construction of standardized biobanking of biospecimen and databases for sarcopenia is crucial for further deepening research and facilitating translational application of the disease.Due to the absence of unified consensus in this field in China and abroad,Biobank Branch of China Medicinal Biotech Association,Department of Geriatrics and Biological Resource Center of Renji Hospital-Shanghai Jiao Tong University School of Medicine have jointly formulated this consensus with experts in the field of geriatrics,biobanking management,and basic and clinical research on aging,aiming to promote the construction of high-quality biobank and database for sarcopenia,so as to promote sarcopenia research,precision diagnosis and treatment and clinical transformation.
