ABSTRACT=BackgroundOccupational risks contribute substantially to the global burden of pneumoconiosis, chronic obstructive pulmonary disease (COPD), tracheal-bronchus-and-lung (TBL) cancer, and asthma; however, comprehensive, up-to-date global, regional, and national estimates remain limited.MethodsData from the Global Burden of Disease Study (GBD) 2021 were analyzed to quantify the burden of these diseases attributable to occupational exposure across 204 countries between 1990 and 2021, stratified by sex, age, socio-demographic index (SDI), and geographic region.ResultsIn 2021, occupational risks led to 30,546 deaths due to pneumoconiosis, 285,628 deaths due to COPD, 585,451 deaths due to TBL (the highest among the four diseases), and 18,315 deaths due to asthma, with disability-adjusted life years (DALYs) of 1.8, 6.1, 12.6, and 0.4 million, respectively. Male patients exhibited higher burdens of all diseases, reflecting greater exposure to male-dominated industries. Geographically, middle SDI regions had the highest absolute cases for pneumoconiosis and COPD, high-SDI regions for TBL cancer, and low-middle SDI regions for asthma. While age-standardized rates declined for most outcomes over time, the absolute burdens increased owing to population growth and aging, with demographic factors driving up to 80% of the increase in total cases. Health inequities persisted, with lower SDI regions bearing a disproportionate burden, despite modest improvements in absolute inequalities.ConclusionThese findings highlight the need for strengthened occupational health regulations, targeted interventions in high-risk regions, and policies addressing population dynamics to mitigate the impact of workplace exposure on respiratory health.
