Authors' conclusion
In most countries, especially in low-income and middle-income countries, diabetes treatment has not increased at all or has not increased sufficiently in comparison with the rise in prevalence. The burden of diabetes and untreated diabetes is increasingly borne by low-income and middle-income countries. The expansion of health insurance and primary health care should be accompanied with diabetes programmes that realign and resource health services to enhance the early detection and effective treatment of diabetes.

Pooled result
As reported in the abstract
2022
- Adults with diabetes in 2022
- 828 million (95% CrI 757-908)
- Increase in adults with diabetes from 1990
- 630 million (554-713)
- Countries with increased age-standardised prevalence (posterior probability >0.80), 1990–2022
- 131 for women; 155 for men
- Adults aged ≥30 years with diabetes not receiving treatment in 2022
- 445 million (95% CrI 401-496); 59%; 3.5 times the number in 1990
- Countries with increased treatment coverage (posterior probability >0.80), 1990–2022
- 118 for women; 98 for men
