This youth suicide prevention research project is an example of a partnership between Carrier Sekani Family Services (CSFS) and the University of Northern British Columbia (UNBC), funded by the Canadian Institutes of Health Research (CIHR), Institute of Aboriginal Peoples' Health, that directly responds to goals of ethical research conducted in First Nations' communities. Through the use of mixed methods, the project investigated the effectiveness of community-based interventions in preventing suicide and tracked youth self-esteem, depression, and other indicators over the course of the project. The knowledge gained from this research project will help guide CSFS and its member communities in offering programs and services that will assist in reducing incidence of suicide.

The Indigenous population of Canada faces an increased burden of chronic disease, leading to decreased life expectancy. Physical activity is an important health behaviour that improves chronic disease risk factors and physical fitness. The objective of this systematic review was to evaluate physical activity interventions in the Indigenous population in Canada to determine effects on physical activity rates, physical fitness, and health outcomes. MEDLINE, PsycINFO, EMBASE, and CINAHL were searched for peer-reviewed journal articles. Inclusion criteria were studies that examined a physical activity intervention delivered in Indigenous communities in Canada for adults over 18 years of age. Data was extracted and two authors independently rated quality of the evidence. Five studies were included in the narrative synthesis. Interventions were community-based, and three were multi-component interventions focused on preventing or managing type II diabetes. The interventions varied in their success in altering physical activity rates, with increases (n = 2), a decrease (n = 1), or non-significant changes reported (n = 2). No study reported any measure of physical fitness. BMI was reported in four studies, with only one reporting a significant decrease. Decreases in systolic blood pressure and total cholesterol were reported in two studies. There is limited evidence and a lack of robust interventions that examine the impacts of physical activity on health and fitness status in the Canadian Indigenous population. Validated, culturally relevant tools for measuring physical activity may aid in program evaluation and focused educational materials could better support population health initiatives.Trial registrationThe review protocol was registered prospectively with PROSPERO (registration number: CRD42017055363).
