A Nature Aging perspective argues that productive engagement in later life — paid work, volunteering and family caregiving — operates as a multidimensional determinant of healthspan, economic security and social cohesion. The authors call for a shift from observational description toward intersectional, experimentally tested interventions that address disadvantages accumulated across the life course.
Key Points
- Employment, volunteering and caregiving jointly shape later-life healthspan
- Observational evidence dominates; experimental intervention trials remain scarce
- Access to productive roles reflects accumulated life-course disadvantage
Longevity Analysis
Healthspan extension depends on structural access to meaningful roles, not solely on individual biology or behavior. Those entering later life with constrained employment histories, caregiving burdens or limited social capital face compounding disadvantage that biomedical interventions alone cannot correct. Designing and testing policy-level interventions that expand productive engagement represents an underused lever for population-scale healthy aging.
