Nowadays， many countries around the world are facing the problem of population ageing， especially China. Older adults have become the main population with disability， and with the constant increase in the elderly population with disability， there is an increasing demand for care and nursing， which not only imposes a great economic burden on individuals and their families， but also causes pressure to the society. A large number of studies have shown that early accurate assessment and intervention for disability-related conditions in older adults are effective measures to delay the progression of disability， while at present， there are still no specific guidelines for the categorical assessment of disability in older adults in China or around the world. Although some existing guidelines cover several aspects of disability-related assessment， they do not strictly follow the framework of International Classification of Functioning， Disability， and Health and fail to grasp the overall characteristics of disability-related conditions， and therefore， such guidelines show an unsatisfactory application effect in Chinese clinical practice. To fill in this gap， the guidelines for categorical assessment of disability in old age suitable for the national conditions of China are developed based on existing evidence-based medicine evidence and the values and preferences of older adults in China， with the application of Grading of Recommendations Assessment， Development and Evaluation. Finally， 12 recommendations are formed for the assessment of older adults with disability， in order to identify the older adults with disability and perform interventions in the early stage， delay the progression of disability， and contribute to healthy aging.
