The self-reported behaviour of Iiyiyiu Aschii Cree and the worry about pollution from industrial and hydroelectric development in northern Quebec, Canada

Worry is influenced by environmental pollution and affects individual health and well-being; however, little is known about this association in Indigenous communities. Using logistic regression models, we examined self-reported responses among Cree adults to the question “Are you worried about the pollution of the environment (land, water or air) in Iiyiyiu Aschii?” to assess if increased worry was associated with proximity to industrial and hydroelectric development, whether increased worry was associated with self-reported behavioural changes of water consumption type in the community or bush, and days spent on-the-land. Proximity to multiple industrial and hydroelectric development sites was associated with increased worry about pollution. Notably, the decreased consumption of tap water in the community was significantly associated with increased worry, but time-on-the land was not. Overall, our study provides new findings concerning development in a Cree territory in northern Quebec, Canada, and the worry about pollution's association with self-reported behavioural changes. •The worry about pollution in Indigenous communities is not well understood.•Pollution worry increases near proximity to industrial or hydroelectric development.•Increased worry about pollution leads to decreased community tap water consumption.•Indigenous knowledge-based strategies for pollution mitigation are encouraged.
