Global, regional, and national burden and trends of air pollution-related neoplasms from 1990 to 2019: An observational trend study from the Global Burden of Disease Study 2019

Abstract

BackgroundAir pollution-related neoplasms are a major global public health issue and are one of the leading causes of death worldwide. Air pollution is one of the important risk factors of air pollution-related neoplasms and is associated with a variety of air pollution-related neoplasms.The primary objective of this study was to estimate the epidemiological patterns of death rates and disability-adjusted life years (DALYs) associated with air pollution-related neoplasms on a global scale, covering the period from 1990 to 2019. Furthermore, we aimed to predict the trends in these epidemiological patterns up to 2050. By achieving these goals, our study seeks to provide a comprehensive understanding of the potential causes underlying the observed disparities in neoplasm-related health outcomes, ultimately contributing to the development of effective strategies for addressing this major public health issue. MethodsBased on data from the 2019 Global Burden of Disease (GBD) study, the indicators of the air pollution-related neoplasms disease burden was the numbers and age-standardized rates (ASR) of deaths and disability-adjusted life years (DALYs) from 1990 to 2019. First, we compared the burden of air pollution-related neoplasms and temporal trends by gender, age, socio-demographic index (SDI), region, and country. Furthermore, driving factors and improvement potential were evaluated using decomposition and frontier analysis. Finally, forecasting analyses of the changing trend in the burden of air pollution-related neoplasm up to 2050 was conducted based on time series forecasting models. ResultsIn 2019, air pollution-related neoplasms accounted for 387.45 million (95 % UI 288.04–490.06 million) deaths and 8951.97 million (95 % UI 6680.89–11342.60 million) DALYs globally. Deaths and DALYs demonstrated an upward trend from 1990 to 2019, while their ASR showed a downward trend. The disease burden and the decline degree of males were both significantly higher than that of females, and the high burden was mainly in the elderly groups. The middle SDI region possessed the highest burden with the most significant upward trend, while the high SDI region had the lowest burden with the most significant downward trend. Decomposition analyses represented that the increase in the overall deaths and DALYs of air pollution-related neoplasms was mainly driven by population growth. The predictive analyses expected that the deaths and DALYs of air pollution-related neoplasms will continue to rise, while their corresponding ASR will decrease by 2050. ConclusionThe global burden of air pollution-related neoplasms remained high, and deaths and DALYs will be on upward trends up to 2050, with differences among genders, ages, SDI levels, GBD regions, and countries. It is essential to understand the air pollution-related neoplasm burden and contributing epidemiological factors for implementing effective and factor-tailored interventions to reduce the global burden.
