About

The goal of this observational study is to establish the prospective cohort of the Beijing Longitudinal Disability Survey in Community Elderly (BLINDSCE) to explore the high-risk factors and preventive interventions for disability and cognitive impairment among community-dwelling adults aged 65 years and over. The main question it aims to answer is:

• What are the high-risk factors able to predict the incidence and advance of disability and cognitive impairment in community-dwelling adults aged 65 years and over?
• What are the categories of function and cognitive performance trajectory in community-dwelling adults aged 65 years and over?

Full description

BLINDSCE is a community-based prospective cohort study that includes individuals aged 65 and over from urban and rural areas in Beijing. Participants will provide detailed demographic information and undergo multifactorial questionnaires, disability measurements, cognitive assessments, other disability-related outcomes, and clinical biochemical measures. The study has started recruitment and enrollment in 2023 and will follow-up once every 1-2 year. This work consists of three steps as follows. First, by collecting baseline and follow-up data of participants, we plan to establish a community-dwelling elderly database in Beijing. Second, high-risk factors can be pre-screening based on this cross-sectional analysis. Third, longitudinal data was used to develop the prediction model and trajectory analysis for disability and cognitive impairment.
