This research project focuses on life-course mechanisms of stress and stress regulation in old age and the role of reserve build-up and activation in a multi-domain approach (education, work, family, leisure and welfare regimes). Vulnerability is proposed to be the result of insufficient reserve build-up across the life course in various domains, linked with inefficient reserve activation in situations of stress, in the context of insufficient systemic (e.g. welfare state) measures to offset or prevent negative outcomes.
In LIVES interdisciplinary approach, reserves are described as a dynamic function, latent capacity, that build up across the life course and indicates the main available capacity to maintain the functionality of a physiological, cognitive, or social system after receiving a shock or a stressor. They are needed for protection against damage or stress, to delay or change the processes of decline in well-being, mental and physical health, economic status or social participation across old age.
IP3–Ageing focuses its studies to tackle two research gaps:
- Longitudinal and experimental research designs.
- Activation of reserves in stress situations, both in controlled settings and in measurements-burst designs in everyday life.
Research questions
How are reserves built up in various domains across the entire life course to buffer against stress effects in old age?
The concept of multi-domain reserves is examined as a potentially powerful interdisciplinary explanatory construct that may be used to better understand long-term trajectories into vulnerability in old age. From a life-course perspective, we consider these dynamics as starting in childhood, across the whole adult life course and into old age. Vulnerability is related to a lack of reserves in multiple domains when facing episodes of stress such as unemployment, retirement, major health problems or bereavement. We aim to delineate those episodes across the life course, and combine and interrelate different domains. Gender differences or social stratification are also considered as principal moderators.
How are multi-domain reserves activated in situations of stress by older adults and how do they interact?
This second project focuses on reserve activation in situations of stress. Older adults may be more prone to negative stress effects on their cognitive health than younger ones as a result of a lack of reserves. We aim to examine how reserve levels are activated in situations of stress and whether this differs between men and women.
