Beijing Longitudinal Study on Disability and Cognitive Health in Adults 65 and Older

What this Trial Is About

This observational study focuses on community-dwelling adults aged 65 years and older in Beijing. It aims to explore the high-risk factors that predict the development and progression of disability and cognitive impairment in this population. The study also seeks to identify patterns of functional and cognitive performance over time to better understand ageing-related changes. Participants will provide detailed demographic information and complete a series of questionnaires assessing multiple factors related to disability and cognition. Disability measurements, cognitive assessments, and clinical biochemical tests will be conducted. The study started recruiting in 2023 and will follow participants every 1 to 2 years to collect ongoing data. Throughout the study, researchers will evaluate disability from both the individuals and medical perspectives, along with cognitive impairment, subjective cognitive decline, intrinsic capacity, frailty, muscle strength, physical performance, sarcopenia, hospitalization, and mortality. This long-term follow-up will help develop prediction models and track changes in disability and cognition over time. Participation involves repeated assessments and data collection over several years.
