Authors' conclusion
The global burden of prediabetes is substantial and growing. Enhancing prediabetes surveillance is necessary to effectively implement diabetes prevention policies and interventions.
Study context
- Population

- Outcome
- Prevalence of prediabetes (IGT or IFG)
- Follow-up
- 2021 and projections for 2045
Methodological detailslogistic regression, age-standardized, extrapolation for countries without data
