Global Inequalities in the Burden of Digestive Diseases From 1990 to 2019: Findings From the Global Burden of Disease Study 2019

We read with great interest the study of Wang et al1 that investigated the global burden of 18 digestive diseases stratified by sociodemographic values and the levels of super regions, regions, countries, and territories. They reported a significant decrease in the global burden of digestive diseases from 1990 to 2019 and the varied burden among countries with different development levels,1 which attracted our attention. Another study about global digestive diseases also mentioned a significant disparity in the burden according to the sociodemographic index (SDI) and geographic region.
