About the Study

The Canadian Alliance for Healthy Hearts and Minds First Nations (CAHHM-FN) study involves a strong partnership between academic institutions and First Nations communities. Eight First Nations communities across many parts of Canada enrolled 1,302 participants over the age of 18 from 2013 to 2018. The governance model of the CAHHM-FN is such that each community owns their data, controls its dissemination, and decides when and what research is in the best interests of their specific community. Overall data from the cohort is held centrally under the stewardship of Dr. Sonia Anand, at the Population Health Research Institute (PHRI), McMaster University. Joint analyses and new data collection is undertaken only with the permission of the Local Community Advisory Boards (LCAB) established for oversight of the study.

The Health Services Research and Cardiovascular Questionnaire (HSR) examines participants’ access to health care services, such as visits to a primary care provider or the emergency department, or language barriers affecting care provision. The questionnaire also collects information focused on cardiovascular risk factors, history of cardiovascular diseases, and medication use. View the HSR questionnaire.

Social capital data was collected via the CAHHM Community Contextual Factors Questionnaire, which was replicated from the Environmental Profile of Community Health (EPOCH-2) instrument that has been studied and validated in five countries, including Canada (Anand et al., 2018b; Chow et al., 2010; Corsi et al., 2012). The questionnaire assesses the individual contextual factors in the built environment of participants in the study that may have an impact on health, such as: community advertising related to smoking/tobacco, food, alcohol, and physical activity; community environments related to tobacco, alcohol, nutrition/physical activity, and socializing; relationships with family and friends; civic engagement; life satisfaction; individual home and workplace environment.
