- Key highlights
- The study tracks age-related health trajectories among adults aged 45 years and older, capturing multidimensional outcomes including cognitive function, disability, mental health, chronic conditions, and family support structures. As India’s first nationally representative longitudinal study on ageing, its findings have directly informed national policy on ageing, elder care, and pension systems.Key findings of the study indicate a high prevalence of frailty (25.5%) and very low engagement in formal employment, highlighting critical gaps in geriatric healthcare and social security planning.
