Studying military and Veteran health using a life-course approach: Lessons learned from a Canadian record linkage study

LAY SUMMARY The Canadian Forces Cancer and Mortality Study (CFCAMS) is an example of a study that uses the life-course approach to research. This article provides an overview of CFCAMS challenges and solutions. Institutional challenges arise from the different mandates of the Department of National Defence and Veterans Affairs Canada. These challenges were addressed by collaboration with Statistics Canada. Data-driven challenges were addressed by data linkage in a secure environment at Statistics Canada. Budget-based challenges could be addressed only for topics that aligned with funded priorities. Human-resource-related challenges include recruitment and retention of experienced personnel, and addressing these challenges is an ongoing issue. These interconnected challenges can leave gaps that result in unrealized stakeholder expectations. Policy-relevant research must incorporate these expectations. Understanding the roles and structures required to generate life-course research can lead to increased influence on policy and practice.
