目的探究社会剥夺与肝癌发病率的空间关系,为肿瘤防治和社会资源合理配置提供参考依据。方法以深圳市为例,以街道为研究单元,利用主成分分析法构建深圳市社会剥夺指标体系,运用地理加权回归定量分析肝癌发病率与社会剥夺的空间关系。结果社会剥夺指数与肝癌发病率之间正相关,提示社会剥夺程度越高的街区肝癌发病率越高。此外,两者之间的线性关系呈现出显著的空间非平稳性。结论肿瘤预防措施的制定应充分考虑地区居民收入、教育、住房等社会经济因素。
Objective To explore the spatial relationship between social deprivation and the incidence of liver cancer and provide a reference for the prevention and treatment of cancer and the rational allocation of social resources. Methods Taking Shenzhen as an example, the street was taken as a unit of study. The social deprivation index system of Shenzhen was constructed by using principal component analysis and the spatial relationship of incidence of liver cancer and social deprivation was quantitatively analyzed by using geographical weighted regression. Results The social deprivation index was positively correlated with the incidence of liver cancer, suggesting that the higher the incidence of liver cancer, the higher the degree of social deprivation. In addition, the linear relationship between the two shows a significant spatial non-stationary. Conclusion The development of cancer prevention measures should take full account of the socio-economic factors such as income, education and housing in the area.
