The findings of a recent study revealed a significant decline in chronic obstructive pulmonary disease (COPD)-associated mortality in China from 2014 to 2021, with age-standardized mortality rates dropping from 91.85 to 45.90 per 100,000 people. However, the disease burden remains high in underdeveloped regions, particularly in rural areas where mortality rates were higher compared to urban regions. The decline in mortality was more pronounced in urban areas (average annual percentage change [AAPC], -10.9%) compared to rural areas (AAPC, -8.3%). COPD, primarily caused by air pollution and smoking, remains the leading underlying cause of death, with older adults being the most vulnerable due to age-related lung function decline. Comorbid conditions like pulmonary heart disease and other respiratory diseases were frequent contributors to COPD-related deaths.
The researchers highlighted the uneven distribution of healthcare resources and called for region-specific strategies to address the disease burden. They emphasized the importance of targeted prevention and management strategies, particularly in rural and underdeveloped areas, to mitigate the impact of COPD.
