Global Burden and Forecast of Fall‐Related Respiratory Foreign Body Aspiration in Older Adults (1990–2040): A Systematic Analysis

Foreign body in the respiratory system caused by falls (F-RFBA) among individuals aged 70 years and older has been a growing concern globally, yet comprehensive global epidemiological data on this issue remain sparse. Data from the Global Burden of Disease (GBD) study from 1990 to 2021 are systematically reviewed to assess incidence, prevalence, and years lived with disability (YLDs) associated with F-RFBA. Projections are made for the period up to 2040 using Bayesian age-period-cohort (BAPC) models. From 1990 to 2021, the incidence, prevalence, and YLDs associated with F-RFBA among individuals aged 70 years and older showed an increasing trend. High SDI regions maintain a substantial burden, contrasting with Central Europe's decline. Global incidence is projected to increase 33.6% (2021-2040), with regional variations: decreases in Australia/New Zealand and sub-Saharan Africa versus rises in China and the United States. The global burden of F-RFBA among individuals aged 70 years and older has shown an increasing trend from 1990 to 2021 and is projected to rise further through 2040. Significant disparities in disease burden and trends underscore the need for targeted interventions, healthcare strengthening, and effective prevention strategies.
