India bears the heaviest burden of chronic respiratory diseases in Asia, accounting for more than 43 percent of the region’s disability related to lung conditions, according to a new scientific analysis. The findings underline the scale of India’s public health challenge and point to air pollution as a major contributing factor behind the country’s persistently high disease burden.
The study is based on estimates from the Global Burden of Disease 2023 and focuses on disability adjusted life years, a measure that reflects both premature deaths and years lived with illness. According to the analysis, Asia as a whole contributed nearly 67 percent of global disability adjusted life years caused by chronic respiratory diseases in 2023.
Among Asian countries, India recorded the highest share, accounting for 43.3 percent of the region’s total burden. China followed with 27.8 percent, meaning the two countries together made up more than 70 percent of Asia’s lung disease related disability. Researchers noted that this trend is largely influenced by population size, long term exposure to environmental risk factors, and rapid urbanisation.
Air pollution emerged as one of the most significant contributors to chronic respiratory diseases in India. Prolonged exposure to polluted air, including fine particulate matter from vehicles, industries, construction activities, and household fuel use, continues to affect millions of people. Experts have repeatedly warned that poor air quality increases the risk of conditions such as asthma, chronic obstructive pulmonary disease, and other long term lung disorders.
The study highlighted that despite economic growth and improvements in healthcare access, India continues to face challenges in reducing exposure to environmental risks. Rapid urban expansion, rising energy demand, and reliance on fossil fuels have contributed to sustained air pollution levels in many parts of the country.
Researchers also pointed out that chronic respiratory diseases place a significant strain on healthcare systems. Long term treatment, frequent hospital visits, and reduced productivity contribute to both economic and social costs. Vulnerable populations such as children, older adults, and people with pre existing health conditions are particularly at risk.
Across Asia, the high share of lung disease related disability reflects broader environmental and demographic trends. Many countries in the region face increasing pollution, aging populations, and lifestyle changes that heighten health risks. The study suggests that without stronger preventive measures, the burden of chronic respiratory diseases could remain high in the coming years.
Public health experts have stressed the need for coordinated action to address air quality, promote cleaner energy sources, and strengthen early diagnosis and treatment. Improving monitoring systems and enforcing pollution control regulations are also seen as key steps toward reducing long term health impacts.
The findings serve as a reminder that addressing environmental factors is essential for improving respiratory health outcomes. Reducing air pollution, experts say, could significantly lower the burden of lung diseases and improve quality of life for millions across India and the wider Asian region.
