Although recent literature completed in the United States shows that individual exposure to adverse childhood experiences (ACEs) is generally declining on a national level, analyses have not yet determined how these trends are experienced within diverse demographics, specifically related to race, gender, and socioeconomic status. Further description of how ACEs are experienced within marginalized groups can inform broader policy and preventative interventions. This narrative review explored the national data related to ACEs and subsequent health outcomes among Indigenous peoples in Canada in order to consider population-level trends. In Canada, Indigenous communities continue to confront experiences of intergenerational trauma and family disruptions due to histories of residential schools and overrepresentation in both child welfare and criminal justice systems. This review of national data indicated that, overall, ACEs are increasing within Indigenous populations, and Indigenous peoples experience ACEs more frequently than non-Indigenous peoples. It is possible that the well-documented health disparities within Indigenous populations are partially related to increased exposure to ACEs and are mediated by intergenerational traumas. Potential policy and treatment implications to inform broader public health approaches of ACE prevention and treatment are discussed.
Public Significance StatementThe current findings suggest that, within publicly available population-health data, exposure to ACEs may be increasing among Indigenous families in Canada despite national trends suggesting such exposure is decreasing among general populations. Culturally relevant interventions that can both prevent and mitigate the effects of ACEs among Indigenous communities are required.
