The research aims to explore how shifts in social isolation and loneliness are connected to changes in cognitive-functional impairment among older Chinese adults.
Analyzed four waves of CLHLS data from 2008 to 2018.
Developed a cognitive-functional impairment indicator using MMSE and ADL metrics.
Applied a two-state Cox regression model to evaluate the effects of social isolation and loneliness changes.
44.54% of observations were aged 81-95 years, with 51.14% being female.
18.24% of respondents experienced increased loneliness, 11.10% experienced social isolation.
13.91% exhibited cognitive impairment and 10.45% had functional limitations.
Changes in loneliness had a more significant impact on cognitive-functional impairment transitions than social isolation.
