Background
The global rise in obesity has led to an increasing burden of hepatocellular carcinoma (HCC) associated with high BMI, alongside viral hepatitis. This study evaluates the global burden of HCC due to high BMI, using the Global Burden of Disease (GBD) framework.
Methods
Data from GBD 2021 were analyzed to compare age-standardized death rates (ASDR) and disability-adjusted life-years (ASR) of DALYs for high BMI-associated HCC from 1990 to 2021. The Estimated Annual Percentage Change (EAPC) was calculated using linear regression, and the Nordpred model was applied for projections from 2022 to 2040.
Results
From 1990 to 2021, both ASDR and ASR of DALYs for high BMI-associated HCC showed significant increases. The burden was higher in males, older age groups (especially 80+), and regions with intermediate SDI values. Projections suggest that the global burden will continue rising until 2040 but at a slower rate, potentially stabilizing by then.
Conclusion
The global burden of high BMI-associated HCC is increasing, especially in males and the elderly. Tailored prevention and treatment strategies are crucial to address regional trends and mitigate the growing disease burden.
