Population ageing is an inherent and ongoing process characterised by a gradual deterioration in an individual&rsquos physical, cognitive, and social capabilities. There is a growing shift in focus from simply increasing longevity to extending &ldquohealth span&rdquo, i.e. the number of years spent in good health. The World Health Organization has defined healthy ageing, as the process of developing and maintaining functional ability that enables well-being among older adults. The population of older adults in India is expected to rise to 41 percent by 2031, and hence there is a need to address the issues associated with healthy ageing. Further, the association of childhood health, multimorbidity, social capital with healthy ageing is yet to be explored in the Indian context. The study will examine the nexus between childhood health, multimorbidity and social capital with healthy ageing. Additionally, the study will seek to analyse the socio-economic inequalities in healthy ageing. Data will be extracted from Longitudinal Ageing Study in India (LASI) wave 1 conducted during 2017-18 for the present study. Appropriate econometric models will be used for empirical analysis in order to understand the multifaceted approach to healthy ageing. The findings of this study will have policy relevance and contribute significantly to a comprehensive and equitable approach to healthy ageing, ensuring a better quality of life for older adults.
