Objective To analyze the gender-specific distribution patterns of the disease burden of tracheal, bronchial, and lung cancer (hereinafter referred to as lung cancer) attributed to tobacco from 1990 to 2021 globally and in China and the United States (US), and to predict the trend of disease burden changes from 2022 to 2031, aiming to provide multi-dimensional evidence-based support for optimizing tobacco control strategies and precise lung cancer prevention and control systems. Methods Data on the disease burden of lung cancer attributed to tobacco from 1990 to 2021 globally and in China and the US were extracted and integrated from the Global Burden of Disease (GBD) 2021 database. The Joinpoint 4.9.1.0 software was used to analyze the corresponding trends in disease burden. The Bayesian age-period-cohort (BAPC) prediction model was employed to forecast the disease burden of lung cancer from 2022 to 2031. Results In 2021, China had the highest number of deaths and disability-adjusted life years (DALY) due to lung cancer attributed to tobacco, with 544600 patients and 12.5721 million person-years respectively, followed by the US with 105200 patients and 2.3096 million person-years. The top three risk factors for lung cancer globally and in China and the US from 1990 to 2021 were tobacco, air pollution, and occupational risks. The disease burden of lung cancer patients attributed to tobacco has been decreasing year by year in the global and US populations [the average annual percentage change (AAPC) values of age-standardized mortality rate and DALY rate were: globally: −0.96%, −1.28%; US: −2.33%, −2.72%], while it has been increasing in China (the AAPC values of age-standardized mortality rate and DALY rate were 0.28% and −0.02%, respectively). From a gender perspective, the disease burden of male patients with lung cancer attributed to tobacco was much higher than that of female patients from 1990 to 2021. Compared to the global average, the disease burden of lung cancer attributed to tobacco in China and the US from 1990 to 2021 was still heavy, with China's burden being higher than that of the US. The elderly population aged ≥65 years in both the global context and in China and the US was the primary group affected by the disease burden of lung cancer attributed to tobacco. The BAPC prediction model indicated that from 2022 to 2031, the age-standardized rates of lung cancer attributed to tobacco in the global context and in China and the US would show a declining trend. Conclusion From 1990 to 2021, the disease burden of lung cancer attributed to tobacco in China and the US was still heavy compared to the global average, with China's burden being significantly higher than that of the US. The focus on prevention and control for both countries remains among the middle-aged and elderly population (especially males), which is a key challenge for tobacco-related lung cancer prevention and treatment work in the next 10 years.
