- The study evaluates the instability and inconsistency of Global Burden of Disease (GBD) risk factor estimates for mortality and disability-adjusted life-years (DALYs) across GBD iterations from 2010 to 2023.
- Findings show significant fluctuations in death and DALY estimates, with a median ratio of minimum to maximum range to the mean (R:M) of 0.8 for deaths and 0.7 for DALYs.
- Dietary risks and child and maternal malnutrition estimates exhibited high instability, with R:M >1 for many subcategories.
- Comparisons between original and revised estimates revealed median R:M values of 0.4 for both deaths and DALYs, indicating substantial revisions over time.
- A high proportion of point estimates for specific dietary components (e.g., red meat, sugar-sweetened beverages) in GBD 2021 fell outside the 95% uncertainty intervals of GBD 2019 estimates.
- The study concludes that GBD estimates are notably unstable, especially for behavioral risks, suggesting caution in their interpretation and use.
