The burden of type 2 diabetes in China from 1990 to 2021: A comparative analysis with G20 countries using the global burden of disease study 2021

Objectives: The study aims to evaluate the burden of Type 2 Diabetes (T2D) in China from 1990 to 2021, and compare to it across G20 countries. Methods: We utilized data from the Global Burden of Disease Study 2021 to examine the burden of T2D in China from 1990 to 2021. Prevalence, mortality, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) were calculated. Comparative analyses were conducted with other G20 countries. Results: T2D prevalence in China increased between 1990 and 2021, with rates rising from 3519.8 (3138.3-3910.1) to 6055.5 (5510.1-6614.3) per 100,000. The death rates slightly decreased from 9.3 (8.2-10.5) per 100,000 to 8.7 (7.3-10.3). The DALYs rate increased from 438.7 (358.5-531.5) to 569.8 (435.4-734.2), with increases observed in YLDs and YLLs. Males had a heavier disease burden in China. Compared to G20 countries, China ranked high in prevalence but had relatively better mortality outcomes in older age groups. Conclusion: This study reveals the enormous burden and remarkable control efforts of T2D in China. Comparative analysis emphasizes the importance of tailored public health interventions to address this growing health crisis.
