How does the joint association of uPDI and LAE affect cognitive impairment in Chinese older adults?
The study aimed to investigate the combined effects of leisure activity engagement (LAE) and the urban physical deprivation index (uPDI) on cognitive impairment in Chinese older adults. The data was collected from the Chinese Longitudinal Healthy Longevity Survey, including 10,617 individuals aged 65 years and older who were free of cognitive impairment or dementia at baseline. Cox proportional hazards models were used to analyze the joint association of uPDI and LAE with cognitive impairment. The results showed that individuals with high scores of LAE and low uPDI had a decreased risk of cognitive impairment compared to those with low scores of LAE and high uPDI. Additionally, stratified analysis revealed that high scores of LAE had a protective effect on cognitive function, regardless of uPDI levels.
This study provides evidence that the joint effects of uPDI and LAE play a role in cognitive impairment among Chinese older adults. The findings suggest that maintaining a high level of engagement in leisure activities, combined with a low level of urban physical deprivation, can help reduce the risk of cognitive decline. These results highlight the importance of promoting leisure activity participation and improving urban physical environments as strategies for preventing cognitive impairment in older adults.
How does diversified leisure activity participation impact cognitive function in Chinese elderly individuals?
This large-scale cohort study aimed to examine the relationship between diversified leisure activity participation and cognitive function in Chinese elderly individuals. The study used a within-person design to separate between-person effects and within-person effects. The findings showed that there is a reciprocal relationship between diversified leisure activity participation and cognitive function over time. Increased cognitive function was associated with higher participation in diversified leisure activities, creating a positive feedback loop that further promotes cognitive function.
The study’s results emphasize the importance of engaging in a variety of leisure activities to improve cognitive function in elderly individuals. By participating in diverse leisure activities, individuals can stimulate their cognitive abilities and potentially mitigate age-related cognitive decline. These findings highlight the potential benefits of leisure activity interventions as a strategy to enhance cognitive function and overall well-being in the aging population.
