What is longitudinal research how is it applied to older adults?
Longitudinal studies are key to understanding patterns of ageing and the services which an ageing population is likely to require [1]. Only a longitudinal design can yield information about the dynamics of change as people age, and can thereby suggest how outcomes might be linked to putative in¯uences.
