Development of a Healthy Aging Index (HAI) and exploring patterns of healthy aging trajectories using the Canadian Longitudinal Study on Aging

Project Summary

This project aims to develop a healthy aging index (HAI) based on a multidimensional item response theory framework and identify heterogeneity of the aging pathways using the Canadian Longitudinal Study on Aging data. Drawing on holistic approaches, we generate a measure which could assess multidimensional aspects of healthy aging. This project would provide an important opportunity to explore healthy aging patterns, its associated factors, and distal health outcomes linked to healthy aging patterns. This project would enhance our understanding of diversity in the aging pathways and determinants of healthy aging, which will suggest future directions for policies and interventions to improve health and well-being in later life.
