Contribution of High Body Mass Index to the Global Burden of Esophageal Cancer: A Population-Based Study from 1990 to 2019

The changing patterns of obesity have had a significant impact on the epidemiology of esophageal cancer (EC). This study aimed to investigate the specific burden of EC associated with high body mass index (BMI) across different geographical and Sociodemographic Index (SDI) regions, using data from the Global Burden of Disease Study 2019. Mortality, age-standardized death rates (ASDR), and disability-adjusted life-years (DALYs) from 1990 to 2019 were analyzed for 204 countries and territories. Decomposition analysis, frontier and health inequality analyses, and age-period-cohort models were employed to examine the factors driving disease burden and to predict future trends. High BMI contributed to 89,903.9 [95
