Abstract

Objective To explore the spatial epidemiological characteristics of esophageal carcinoma mortality in Anhui from 2018 to 2020 through spatial epidemiological analysis, so as to determine the key areas of esophageal carcinoma mortality. Methods The surveillance records of esophageal carcinoma death from 2018 to 2020 were collected. The Kriging spatial interpolation method was used to draw the geographical distribution map of esophageal carcinoma mortality. The spatial autocorrelation analysis was performed to explore the spatial distribution regularities of esophageal carcinoma mortality in Anhui Province. The spatio-temporal scan statistic was used to explore the aggregation areas of esophageal carcinoma mortality. Results The crude mortality and age-standardized mortality of esophageal carcinoma in Anhui Province between 2018 and 2020 were 14.92/100 000 and 10.39/100 000 respectively. The mortality of males was higher than that of females in each of these three years (all P < 0.05). The spatial autocorrelation analysis showed that the spatial distribution of esophageal carcinoma mortality in Anhui had the feature of aggregation (Moran's I=0.54, Z=8.84, P < 0.001). The aggregation areas were mainly Lujiang County, Zongyang County and Tongcheng City on the eastern side of Dabie Mountain. The key aggregation areas were the same for females and males. Spatio-temporal scan showed that there were three key aggregation areas of esophageal carcinoma mortality in Anhui (all P < 0.05). Conclusions There are significant differences in the mortality rate of esophageal cancer in Anhui Province among different regions and populations, and there are high-mortality aggregation areas, which are mainly distributed on the eastern side of the Dabie Mountains.
