To explore the impact of social participation on cognitive decline in middle-aged and elderly people, and to provide a reference for improving or maintaining the cognitive health of middle-aged and elderly people.
A total of 6 645 middle-aged and elderly people over 50 years old in the 2018 China Longitudinal Survey on Influencing Factors of Elderly Health (CLHLS) were selected as the research subjects, and cognitive frailty was evaluated by the Mini-Mental State Evaluation Scale (MMSE) and Frailty Index (FI). A multivariate logistic regression model was used to analyze the effects of social participation type and intensity on cognitive weakness.
The higher the participation of middle-aged and elderly people in family activities, individual activities, and group activities, the lower the incidence of cognitive weakness. High participation in family activities had the highest effect on mild (OR=0.271, 95%CI:0.228-0.321), moderate (OR=0.463, 95%CI:0.361-0.592) and severe (OR=0.079, 95%CI:0.043-0.146) cognitive frailty. The incidence of cognitive frailty was negatively moderated by high participation in family activities (OR=2.263, 95%CI:1.579-3.244), and the incidence of cognitive frailty was negatively moderated by urban middle-aged and elderly people in group activities (OR=0.459, 95%CI:0.289-0.727) and high participation (OR=0.490, 95%CI:0.331-0.725).
It is of great significance to increase the enthusiasm of middle-aged and elderly people for social participation, especially family activities, to delay the decline of cognitive frailty.
