Change of leisure activity participation and associations with cognitive frailty in older adults: A population-based longitudinal study

Abstract

ObjectivesTo examine changes in leisure activity participation and their associations with cognitive frailty among older adults. MethodsThe study utilized data from the Chinese Longitudinal Healthy Longevity Survey covering 2008–2018. Three distinct intervals represented short-term (2008–2011), medium-term (2008–2014) and long-term (2008–2018) changes in leisure activity participation, and the change patterns of levels of leisure activities based on the tertile were described. Restricted cubic splines (RCS) were used to determine the inflection point of the absolute value of leisure activity participation over two time points. Group-based trajectory modeling identified trajectories of leisure activity participation among participants from 2008 to 2018. Logistic regression analysis examined how changes in leisure activity participation impacted cognitive frailty. ResultsFive patterns of change in leisure activity participation were identified, including the persistently low group, the declining (medium-low, high-low, high-medium) group, persistently medium, rising (low-medium, low-high, medium-high), and persistently high levels of activity. A lower risk of cognitive frailty was found among three groups of persistently medium, rising, and persistently high levels of activity across three distinct intervals and among the declining group over the short-term and long-term intervals but not in the medium-term interval than among the persistently low group, respectively. RCS analysis showed that the inflection point of the association between absolute changes in leisure activity and cognitive frailty was -2.11 (short-term), -0.9 (medium-term), and -3.94 (long-term). Leisure activity trajectories were categorized into persistently low, persistently moderate, and persistently high groups, and both the persistently moderate and persistently high groups exhibited a lower risk of cognitive frailty compared to the persistently low group. ConclusionPersistently moderate to high levels and increasing levels of leisure activities can reduce the risk of cognitive frailty in the short, medium, and long term, and even the declining in leisure activity participation less than the threshold could protect against cognitive frailty, particularly in the short and long term.
