Sponsor's own description
Background. First Nations peoples in Canada carry an increased respiratory health burden compared to non-First Nations. However, there is little accurate information of how many First Nations people have COPD, especially in remote and rural areas. Goal \& Aims of the Study. The goal of this study is to estimate the burden of COPD in remote and rural First Nations communities. This project is a partnership between the University of British Columbia (UBC), Carrier Sekani Family Services (CSFS), and 13 First Nations communities in northern BC. Aim 1: Estimate the prevalence of COPD and the magnitude of underdiagnosis. Aim 2: Characterize the relationship between inhaled pollutants (from residential, occupational, and community/cultural sources) and: 1) symptoms; 2) airflow obstruction; and 3) health care utilization. Methodology. The investigators will recruit adults from randomly-selected households in 13 First Nations communities in northern BC. Detailed measurements of lung function, symptoms, self-reported exposure to lung irritants, air quality, and healthcare use will be collected. Expected Outcomes. This study will provide an accurate estimate of the prevalence of COPD and, using a culturally-relevant community-based research approach, will identify the contribution of risk factors to COPD in First Nations communities.
