Cross-national Differences in the Association Between Retirement and Memory Decline

Area of Science:

• Gerontology
• Cognitive Aging
• Sociology of Aging

Background:

• Retirement is a significant life transition that can impact cognitive health.
• Societal and institutional contexts influence retirement experiences and outcomes.
• Cross-national variations in welfare systems may affect cognitive aging trajectories post-retirement.

Purpose of the Study:

• To investigate the association between retirement and memory decline.
• To examine cross-national differences in memory trajectories after retirement.
• To identify if institutional contexts, such as welfare systems, moderate the impact of retirement on cognitive aging.

Main Methods:

• Longitudinal analysis of 8,646 individuals aged 50+ from the Survey of Health, Aging, and Retirement in Europe (SHARE).
• Memory function assessed using immediate and delayed word recall over 13 years.
• Three-level linear mixed-effects models were used to analyze memory trajectories, accounting for individual and country-level variations.

Main Results:

• Retirement was associated with a moderate decrement in word recall and accelerated memory decline.
• Significant heterogeneity was observed in memory decline rates across 17 European countries.
• Faster memory decline post-retirement was noted in Mediterranean and Eastern European countries compared to Northern and Central European nations.

Conclusions:

• Retirement is linked to accelerated cognitive decline, with significant cross-national variations.
• Less generous welfare systems and lower pension benefits in certain European regions correlate with more rapid post-retirement memory decline.
• Further research into protective resources for retirees is warranted to mitigate cognitive aging.
