中国女性肺癌发病率的空间分布特征分析
Spatial distribution characteristics of lung cancer incidence in Chinese females
摘要
Abstract
Objective This study aimed to reveal the spatial heterogeneity and spatial aggregation of lung cancer incidence in Chinese females,to quantitatively analyse the correlation between key environmental factors and the incidence of lung cancer,and to provide scientific reference for the prevention and control of lung cancer.Methods Information on the incidence rate of lung cancer in Chinese females was collected through the 2017-2019 Annual Report of China Tumour Registry,data on a total of four environmental factors,namely NO2 concen-tration,urbanisation rate,air temperature and topographic elevation,were obtained from public databases for the same period.Spatial heterogeneity of female incidence rates was revealed using spatial autocorrelation analysis,the ordinary least squares(OLS)method was used to test for multicollinearity of environmental influences,and a geo-graphically weighted regression(GWR)model was used to quantitatively analyse the association with environmen-tal factors and compare the fitting effect with the OLS model.Result The incidence rate of female lung cancer in China showed a spatial distribution pattern of high in the northeast and low in the southwest.The global Moran in-dex was 0.60(P＜0.001,Z=5.41),indicating a spatially aggregated distribution of female lung cancer inci-dence.The results of the GWR model showed that the four environmental factors had different impacts on the inci-dence rate of female lung cancer in different regions.The AICc of the GWR model=80.09,R2=0.37,Adjusted R2=0.26,and its fitting effect was better than the OLS model.Conclusion The high-incidence areas of female lung cancer in China were mainly located in areas with high urbanisation and industrialisation,and there were spa-tial differences in the influence of environmental factors on the incidence of female lung cancer.关键词
