Research collaborations between non-Indigenous and Indigenous researchers primarily have been led by non-Indigenous researchers with privileged locations in university settings. Recognition of the importance of data sovereignty and control to enable Indigenous self-determination requires building data management and analysis capacities among Indigenous research partners. The Canadian Alliance for Healthy Hearts and Minds First Nations (CAHHM-FN) cohort study, a collaboration of 8 First Nations and researchers at 8 universities, convened a 3-day data management and analysis workshop.
