| Summary: | Abstract Background Tobacco is a major risk factor for chronic respiratory diseases (CRDs), yet the global distribution and trends of tobacco-related CRD burdens remain inadequately explored. Methods This study extracted data on mortality, disability-adjusted life years (DALYs), age-standardized mortality rate (ASMR), and age-standardized DALY rate (ASDR) related to tobacco-attributable CRDs from the 2021 Global Burden of Disease (GBD) study. Joinpoint regression was used to identify temporal trends in age-standardized rates (ASR), while autoregressive integrated moving average (ARIMA) forecasting was applied to project future trends in ASMR and ASDR for tobacco-related CRDs. Results In 2021, global tobacco-related CRD deaths and DALYs reached 1,545,686 (95% UI: 1,144,476-1,942,541) and 33,014,429 (95% UI: 24,275,462 − 40,930,821), representing increases of 25.43% and 15.64%, respectively, since 1990. Elderly individuals and males showed a higher disease burden. Between 1990 and 2021, ASMR [average annual percentage change (AAPC) = -2.009 (95% CI: -1.8915 to -2.1263)] and ASDR [AAPC = -2.1057 (95% CI: -2.0123 to -2.199)] for tobacco-related CRDs showed a declining trend globally, with autoregressive integrated moving average forecasting suggesting continued declines in ASMR and ASDR in the future. Regionally, South Asia, East Asia, and Oceania had the highest CRD burdens, while country-specific data indicated that Nepal, Myanmar, Papua New Guinea, Kiribati, and the Democratic People’s Republic of Korea bore significant burdens. The ASMR and ASDR of tobacco-related CRDs were highest in regions and countries with Socio-Demographic Index values between 0.4 and 0.5. Conclusion Although global tobacco-related CRD deaths and DALYs have continued to increase, ASMR and ASDR are on the decline, with variations across geographic regions. Prevention and control strategies tailored to country-specific disease prevalence are essential to mitigate these burdens. |
