Secular incidence trends and effect of population aging on mortality due to type 1 and type 2 diabetes mellitus in China from 1990 to 2019: findings from the Global Burden of Disease Study 2019.

The T1DM and T2DM incidence rates continually increased in China, particularly among young individuals. T1DM-related mortality decreased, while T2DM-related mortality increased in males. Population aging might be associated with a substantial change in the number of deaths from 1990 to 2019. To address the increase in T2DM-related deaths due to population aging, policymakers should promote aging-related health research and implement proven, cost-effective T2DM interventions.
