A significant public health goal is to maximize the healthspan of individuals, the period of life that individuals remain relatively healthy and free of physical and cognitive impairment. Understanding the processes leading to aging-related changes in health, physical function and cognition is a major goal of two research networks of longitudinal studies: The Integrative Analysis of Longitudinal Studies on Aging (IALSA; PI: Hofer, University of Victoria) and Healthy Ageing across the Lifecourse (HALCyon; PI: Kuh, University of London). Statistical analysis for cross-study comparison and integration of research findings across studies affiliated with these two major research networks will be performed. Replication of research findings across independent longitudinal studies is essential for a cumulative and innovative developmental science. A collaborative, coordinated analysis approach can provide a broad foundation for cumulating scientific knowledge by facilitating efficient analysis of multiple studies in ways that maximize comparability of results and permit evaluation of study differences.
