How Spatial Factors Affect Respiratory Health in Coal Resource-based Cities: A Case-control Study in Eastern Yunnan Province, China

Abstract

Urban planning can affect respiratory health. Due to industrial and mining pollution, unique urban and rural spatial structure, etc., the built environment factors of coal resource-based towns have special impact paths on respiratory health. Lung cancer is one of the cancers with the highest incidence and mortality rates worldwide. Qujing City, located in the eastern part of Yunnan Province, China, is dominated by the coal mining industry. Since the survey in the 1970s, it has been the area with the highest incidence of lung cancer in China. Compared with the national average, the standardized mortality rate is 3 times that of men and 5 times that of women. Existing studies are mostly centered on the field of epidemiology, among which there are few studies on spatial influencing factors and the research indicators are single. This study aims to explore the association between environmental factors and the risk of lung cancer in residents in coal resource-based urban and rural areas at different stages of the life course, and propose corresponding intervention measures.
