Leisure activity and cognitive function among Chinese old adults: The multiple mediation effect of anxiety and loneliness

Most countries in the world, including China, are experiencing serious aging problems. The decline of cognitive function seriously affects the quality of life of the elderly in their later years and brings an inevitable heavy burden to the family and society. Therefore, in order to achieve successful aging, the purpose of this study is to test the serial multiple mediation effect of anxiety and loneliness between leisure activity and cognitive function in Chinese elderly population.Using 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS) dataset, we finally selected 6,525 Chinese elderly people over 65 years old after screening. Firstly, we described the basic social demographic information of the sample population. Secondly, Spearman correlation analysis was used to determine whether there is a correlation between leisure activity, anxiety, loneliness and cognitive function in Chinese elderly. Finally, the serial multiple mediation analysis was completed using the SPSS macro PROCESS program.Leisure activity, anxiety, loneliness and cognitive function were significantly correlated (p<0.01). Leisure activity can not only have a direct positive impact on the cognitive function of the elderly (effect=0.2231; SE=0.0122; 95%CI: LL=0.1992, UL=0.2470), but also have an indirect impact on the cognitive function through three paths: the independent mediating role of anxiety (effect=0.0028; SE=0.0015; 95%CI: LL=0.0001, UL=0.0059), the independent mediating role of loneliness (effect=0.0032; SE=0.0016; 95%CI: LL=0.0002, UL=0.0065), and the chain mediating role of anxiety and loneliness (effect=0.0008; SE=0.0004; 95%CI: LL=0.0001, UL=0.0017).All items were self-reported and some results may have biased. In the future, it may be more instructive to explore the impact of specific leisure activity on the cognitive function of the elderly.The study suggests that leisure activity can improve cognitive function through decreasing anxiety and loneliness among the Chinese elderly. Diversified interventions aimed at increasing leisure activity participation in older adults would be beneficial for their mental health and cognitive function.
