Soil properties and spatial distribution of chronic gastritis in Yanshan County, China: a spatial epidemiological study

This study demonstrates that chronic gastritis risk in Yanshan County is shaped by complex interdependencies between demographic characteristics (primarily age) and soil environmental factors. The findings highlight the significant role of soil physicochemical properties and their interactive effects in disease spatial epidemiology. These results provide a scientific basis for identifying geographic hotspots and high-risk populations, emphasizing the necessity of integrating environmental management into targeted public health strategies and resource allocation for gastric disease prevention.
