In this episode of Longevity India, Dr. Sekher highlights the significance of the Longitudinal Ageing Study in India (LASI) in understanding adult health and ageing. As India's first of its kind, LASI focuses on the health, economic, and social well-being of India's older adults, filling the existing gap in comprehensive survey data. Harmonized with international studies, it allows global comparisons while maintaining sensitivity to India's unique characteristics. This national landmark in research provides vital statistical information that can be used to shape evidence-based policies for adults and older people, enhancing our understanding of ageing. Encompassing over 73,000 older adults across India, LASI is scheduled to occur every three years for the next 25 years, enabling the assessment of policy impact on behavioural outcomes. Dr. T. V.
