Embodied Cognitive Reserve in Later Life: Education,Lifelong Learning,and Family-Based Social Support as Predictors of Mortality in the Midlife in the United States (MIDUS) Study

Abstract

Objectives

This study examined whether education predicts mortality among older adults and whether lifelong learning and family-based social support moderate this association within an embodied cognitive reserve framework.

Methods

MIDUS 2 linked to 2016 National Death Index data were analyzed (N = 584; age ≥ 60). Cox proportional hazards models estimated mortality as a function of educational attainment (occupational education index), lifelong learning (PCA-derived factor score), and family-based social support (standardized composite). Interaction terms (education × lifelong learning; education × family support) were modeled to assess buffering effects on the education-mortality link, adjusting for age and sex.

Results

Higher education was associated with lower mortality risk (HR = 0.83, 95% CI [0.73, 0.94]). Lifelong learning strengthened this effect after adjusting for baseline functional limitations. Family-based social support showed a weaker moderating effect.

Conclusions

Findings support the embodied cognitive reserve framework, suggesting that lifelong learning enhances the survival benefits of education.
