Changes in Geographic Variation and Socioeconomic Inequalities in Esophageal Cancer Mortality in China, 1973-2017.

ABSTRACT:

Background

Geographic variability in esophageal cancer has been reported in China, but data are lacking at the local level. We aimed to investigate changes in disparities in esophageal cancer-related mortality among Chinese counties and whether county-level socioeconomic status was associated with this variation.

Methods

We used data from a nationwide survey and population-based cancer registries to calculate esophageal cancer-related mortality rates for 782 Chinese counties for the periods of 1973-1975 and 2015-2017. We performed hotspot analysis to identify spatial clusters. We used a multivariable negative binomial regression model to estimate the associations between county-level socioeconomic factors and mortality.

Results

From 1973-1975 to 2015-2017, the age-sta
