| Summary: | In Canada, accessible and culturally relevant population health data for urban First Nations, Métis and Inuit people are almost non-existent. There is a need for Aboriginal community centric research and data systems, specifically in the area of mental health and substance misuse. The goal of this research was to address these knowledge gaps. The three linked studies being presented were nested in the Our Health Counts (OHC) project, a multi-partnership study aimed at developing a baseline population health database for urban Aboriginal people living in Ontario. In the first study, concept mapping was used to engage urban Aboriginal stakeholders from three culturally diverse communities in identifying health priorities. After completing brainstorming, sorting and rating, and map interpretation sessions, three unique community specific maps emerged. Map clusters and their ratings reflected First Nations, Inuit, and Métis understandings of health. Concept mapping encouraged community participation and informed the development of three health assessment surveys. The second study generated a representative sample of First Nations adults and children living in Hamilton, Ontario by utilizing Respondent Driven Sampling (RDS), a modified chain-referral sampling approach. Population estimates were generated for household and personal income, mobility, over-crowding and food availability. Results revealed striking disparities in social determinants of health between First Nations and the general population. The third study used the RDS generated sample to examine mental health and substance misuse among First Nations adults living in Hamilton. Prevalence estimates were generated for diagnosis and treatment of a mental illness, depression, anxiety, post-traumatic stress disorder (PTSD), suicide, alcohol and substance misuse, and access to emotional supports. Findings indicated that First Nations adults living in Hamilton experience a disproportionate burden of mental health and substance misuse challenges. The three linked studies make innovative contributions to Aboriginal health research. Results clearly exemplify the effective application of community-based research methods that are grounded in local knowledge and built on existing community strengths and capacities. Representative population health data for urban First Nations will contribute to current deficiencies in health information; will shape policy and programming priorities as well as future research directions, particularly with respect to health and social disparities among this population.
