Chronic obstructive pulmonary disease attributable to air pollution in the South Asian countries: global burden of disease study 1990 - 2019.

This study investigates the burden of COPD attributable to air pollution in South Asia using data from the Global Burden of Disease Study from 1990 to 2019. Method Data for this study were obtained from the Global Burden of Disease Study 2019. The burden was measured in terms of death, disability-adjusted life years (DALYs), and Years of life lost (YLLs). Results Since 1990, several countries in South Asia registered substantial declines in mortality rates attributed to COPD, ranging from -37.47% in Pakistan to -66.25% in Bangladesh. Similar trends were observed for DALYs and YLLs as well, which have potentially contributed to a considerable decrease in mortality rates at the regional level (-43.13%) compared to a 32.59% decline in Low SDI and 56.87% decline globally. Conclusion Despite significant declines since 1990, the burden of COPD attributable to air pollution reductions in the South Asian region's rates remains alarmingly high.
