Deaths and disability-adjusted life-years lost due to digestive diseases decreased over the last few decades, according to analyses of the Global Burden of Disease study data. However, incidence and point prevalence remained relatively steady, and there is significant variation across sociodemographic strata in all four measures.
As part of the study, a multicenter team examined data on 18 digestive diseases from over 200 countries to describe trends in age-standardized incidence, point prevalence, deaths and disability-adjusted life-years (DALYs) from 1990 to 2019 (Gastroenterology 2023;165[3]:773-785). The researchers also stratified their results by quintile of the sociodemographic index (SDI), a defined measure ranging from 0 to 1 based on three factors: the total fertility rate of women younger than 25 years of age, the average number of years of education among people aged at least 15 years and the income per capita (lag-distributed).
