“… 23 Developed countries with higher urbanization rates use clean energy as fuel, along with centralized heating and home air purification systems, which significantly reduce the incidence of COPD caused by solid fuel-induced indoor air pollution. 24 , 25 According to surveys, in 2011, only 11.4% of Indian households had access to liquefied petroleum gas, while in 2016 and 2020, 41% and 92% of the population in India, respectively, had access to clean cooking fuel. The Pradhan Mantri Ujjwala Yojana (PMUY) initiative introduced by the Indian government in 2016 provided subsidies for the use of liquefied petroleum gas, benefiting over 80 million households by 2019.…”

Background This study analyzed the burden of chronic obstructive pulmonary disease (COPD) in China, the United States, and India from 1990 to 2019 and projected the trends for the next decade. Methods This study utilized the GBD 2019 to compare the age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), age-standardized disability-adjusted life years (DALYs) rate, and the proportion attributed to different risk factors in China, the United States, and India. Joinpoint models and autoregressive integrated moving average (ARIMA) models were employed to capture the changing trends in disease burden and forecast outcomes. Results From 1990 to 2019, China’s age-standardized COPD incidence and mortality rates decreased by 29% and 70%, respectively. In the same period, India’s rates decreased by 8% and 33%, while the United States saw an increase of 9% in COPD incidence and a 22% rise in mortality rates. Smoking and ambient particulate matter pollution are the two most significant risk factors for COPD, while household air pollution from solid fuels and low temperatures are the least impactful factors in the United States and India, respectively. The proportion of risk from household air pollution from solid fuels is higher in India than in China and the United States. Predictions for 2030 suggest that the age-standardized DALY rates, ASIR, and ASMR in the United States and India are expected to remain stable or decrease, while China’s age-standardized incidence rate is projected to rise. Conclusion Over the past three decades, the incidence of COPD has been decreasing in China and India, while showing a slight increase in the United States. Smoking and ambient particulate matter pollution are the primary risk factors for men and women, respectively. The risk of household air pollution from solid fuels in India needs attention.
