Trends in the study of Aboriginal health risks in Canada.

Objective: To identify trends in the study of health risk in peer-reviewed and grey literature in Canadian Aboriginal populations from 1960 to 2007.

Study Design: Systematic literature review and analysis.

Methods: Peer-reviewed literature was searched using 5 electronic library databases. The grey literature was searched using 3 online search engines, 4 agency websites and 2 online compiled databases. The search terms used were "Canada," synonyms for Canadian Aboriginal peoples and "risk." Citations were screened for relevance to Aboriginal populations and risks to aspects of human health.

Results: Both literatures show an exponential growth in risk-focused study of Canadian Aboriginal health issues over time. There is a geographic foci in the North with the Prairies and the West under-represented. Risk is most commonly used in relation to general health, environmental, zoonotic infections and chronic diseases in the peer-reviewed literature, and general health or environment in the grey literature. Most publications in both literatures are on generalized Aboriginal populations. When specified, a larger proportion of the publications relate to First Nations people, followed by Inuit. Little literature exists on Métis health risks in Canada.

Conclusions: There has been an increase in publications about Aboriginal health risk in Canada over time. Trends reflect a research focus on the North and an increased interest in environment and health issues. Greater attention to mental health, addictions and Métis health is required. The increasing use of a risk-based analytical focus has potential implications for understanding the nature of Aboriginal health today and in the future.
