Burden of type 2 diabetes mellitus and risk factor attribution among older adults: A global, regional, and national analysis from 1990 to 2021, with projections up to 2040
Authors' conclusion
Diabetes cases among older adults have tripled globally since 1990 and are projected to keep increasing. Wealthier nations face diet-related risks, while poorer regions are more affected by environmental factors. Region-specific prevention strategies are urgently needed.
Study context
- Population
- Older adults aged ≥65 years with T2D, global, regional and national, 1990–2021, by sex, age group and Socio-Demographic Index (SDI) level
Methodological detailsBayesian age-period-cohort projection model, annual percentage changes
- Bayesian age-period-cohort projection model
- Annual percentage changes
Primary result
As reported in the abstract
1990 to 2021
Annual rise in age-standardized prevalence
1.9%
Annual rise in age-standardized mortality
0.32%
Mortality rose fastest in the 85-89 age group (annually)
0.52%
Further findings
- High BMI contributed most to T2D burden globally
- High temperature and sugar-sweetened beverages showed the fastest-growing DALY rates
- Fastest-growing risk factor: sugar-sweetened beverages in high-SDI regions, high temperature in low-SDI regions
