Background: COPD among Aboriginal peoples in Canada is a major public health concern. This study was conducted in order to determine the prevalence and association between certain risk factors and COPD among the 35-year-old or older Aboriginal peoples in Canada.
Methods: This is a cross-sectional study. It uses data from Statistics Canada’s Aboriginal Peoples Survey (APS), 2012. It consists of 8,117 self-identified Aboriginal peoples, aged 35 years old or older from all Canadian provinces and territories. The study outcomes centered on evaluating the prevalence and associated factors of COPD.
Results: This study found that 6.80% of the participants self-reported having COPD. Results of the logistic regression analysis show that COPD was significantly higher among daily smokers (odds ratio [OR], 2.28; 95% confidence interval [95% CI], 1.65–3.14), aged 55 years or older (OR, 3.04; 95% CI, 2.14–4.30), who earned $5,000–$9,999 per annum (OR, 4.21; 95% CI, 2.39–7.41) and needed health care over the past 12 months and did not receive it (OR, 1.83; 95% CI, 1.27–2.65).
Conclusion: The findings of our study show that COPD is strongly associated with Aboriginal peoples, who are older, smoke, have a low socioeconomic status (SES) and do not have access to health care when needed. Clinicians, health care professionals, medical/public health organizations, researchers and patients will greatly benefit from additional research in this common, serious and often overlooked disease among Aboriginal peoples in Canada.
