The burden of type 2 diabetes attributable to air pollution across China and its provinces, 1990–2021: an analysis for the Global Burden of Disease Study 2021

Background: Temporal trends and geographical disparities in type 2 diabetes burden attributable to air pollution, including ambient and household, are not fully understood within China. This study aims to estimate the burden of type 2 diabetes attributable to air pollution at national and provincial levels from 1990 to 2021. Methods: ). We employed the methods from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 to estimate the attribution of air pollution on type 2 diabetes deaths and disability-adjusted life years (DALYs) by age, sex, year, and province. Findings: varied widely across provinces, from 143.8 per 100,000 people in Tianjin to 21.6 per 100,000 people in Tibet. Interpretation: , is a significant risk factor for type 2 diabetes in China. Urgent action is needed to enhance air pollution control and develop locally adapted preventive strategies to reduce the burden of air pollution-related type 2 diabetes.
