摘要

Background

Lung cancer is the leading cause of cancer-related death in China. However, its relationship with social–environmental factors has not been revealed comprehensively. We are the first group to determine cold and hot spots associated with the incidence and mortality of lung cancer (IMLC) in both females and males and their spatiotemporal changes and to explore the social‒environmental burden of lung cancer in China between 2007 and 2016.

Methods

The explanatory powers of various social–environmental factors for the IMLC were evaluated through correlation analysis and the Geodetector tool. Spatial analysis models were applied to determine the relationships between the IMLC and social–environmental factors.

Results

The results are as follows: (1) The distribution of the IMLC exhibited significant spatial heterogeneity; the Global Moran’s index values for incidence ranged from 0.04–0.2 and 0.09–0.33 in males and females, respectively, and the values for mortality ranged from 0.01–0.12 and 0.11–0.32 in males and females, respectively. (2) The IMLC was spatially clustered with an overall positive autocorrelation. Male population-related hot spots were observed in the central–southern region of China, and cold spots were observed in western China. Female population-related hot spots were observed primarily in northeastern China. The cold spots occurred primarily in southern and some western regions of China. (3) The effects of social–environmental factors on the IMLC showed significant spatial and temporal variability: in males, the interaction between terrain undulation and road area exhibited the highest explanatory power for the incidence and mortality, with a value of 0.22 for both; in females, the interaction between O3 and road area and the interaction between O3 and the number of medical beds exhibited the highest explanatory powers for the incidence and mortality, reaching 0.27 and 0.34, respectively. (4) The optimal model capturing the relationships between the IMLC and social–environmental factors was the GTWR model, which relies on reclassified data. The best R2 value is 0.456.

Conclusions

The influence of each social‒environmental factor on the IMLC showed significant spatiotemporal variability, providing a systematic basis for governments to implement better targeted control of lung cancer.
