AbstractThis study outlines asthma burden trends across age, sex, regions and risk factors in 'Belt and Road' (B&R) countries from 1990 to 2019 using the Global Burden of Disease Study 2019 data. Incidence, mortality, prevalence, years lived with disability (YLDs), disability-adjusted life years (DALYs) and risk factors for asthma were measured. India, China and Indonesia bore the heaviest burden in 2019. Despite the significant decline in the average annual percent change for age-standardized mortality and years of life lost from 1990 to 2019, increases were observed in several East Asian, Central Asian, North African and Middle Eastern countries between 2010 and 2019. For both sexes, YLDs decreased in most B&R countries but increased in Montenegro, Saudi Arabia, Armenia, Vietnam and Oman. YLDs in Georgia, the United Arab Emirates and Albania increased in males but decreased in females. YLDs increased for those aged <15 years in Central Asia and Europe, while China's 50-74-year age group showed the lowest YLD change. High body mass index (BMI) led to increased YLDs in East, Central and Southeast Asia; North Africa; and the Middle East. Conclusively, asthma burden varies significantly by country. Tailoring control efforts to specific regions, sex and high BMI could enhance asthma management.
