Retirement, Leisure Activity Engagement, and Cognition Among Older Adults in the United States.

Objective: Retirement is a salient later-life transition that may influence cognition. Leisure activities can help individuals better adjust to life after significant life transitions. This study examined the role of leisure activity engagement in the relationship between retirement and cognition. Method: A path analysis (N = 2,827) was conducted using three waves of the Health and Retirement Study (2004, 2006, 2008) and its supplementary Consumption and Activities Mail Survey, to test the association between retirement (categorized as remained working, transitioned to retirement, remained retired) and cognition (memory, working memory, attention, and processing speed) via leisure (mental, physical, social, household) activity engagement. Results: Older adults who remained retired showed significantly lower cognition than those who remained working. Moreover, this negative association between retirement and cognition was attenuated by greater engagement mental activities. Discussion: Interventions that encourage mental activities among retired individuals are strongly suggested to help maintain cognitive function. [ABSTRACT FROM AUTHOR]
