Abstract

Objective: To estimate the lifetime risk of developing hospital‐diagnosed chronic obstructive pulmonary disease (COPD) in Aboriginal people living in remote areas.

Methods: A total of 1,374 participants in a remote community were followed up to 20 years. Individuals with hospital‐diagnosed COPD were identified through hospital records. The lifetime risk of hospital‐diagnosed COPD was estimated using a modified technique of survival analysis.

Results: Of the 1,374 participants, 164 were identified as having incident hospital‐diagnosed COPD during 21,614 person years of follow‐up. After adjusting for the presence of competing risk of death from non‐COPD causes, the lifetime risk of COPD was 53% for the overall population, higher in women (61%) than in men (45%). Adjusting for baseline age and smoking status, women had a significantly higher risk of COPD than men with a hazard ratio (HR) = 1.55 (95%CI 1.13–2.14), while men were more likely to die from non‐COPD causes than women before being diagnosed as having COPD, HR = 2.30 (95%CI 1.64–3.23).

Conclusions: These Aboriginal people have a high lifetime risk of COPD, and one in two have hospital‐diagnosed COPD during their lifetime. Our findings warrant further efforts and resources to combat this condition in remote Aboriginal communities.
