This is a community-based prospective cohort study. Individuals who aged 60 years or older, lived in the communities for more than 1 year, and signed the informed consent form were enrolled in the present study. The study has been initialized in 2023 and aimed to develop an early warning model and a series of disability risk assessment methods for older adults. This work consists of three steps as following. First, we will build a community-based cohort and thus set up a database. Second, an intelligence model for disability risk assessment will be developed using the database. Third, a series of procedures will be established according to the risk assessment model.
