摘要
目的:探索重庆市38个区县肺结核发病率与社会经济发展水平在空间差异下的关系。方法:利用重庆市2011至2014年连续四年的肺结核发病与人均国内生产总值数据,用Spearman秩相关与地理加权回归(geographically weighted regression,GWR)分析当地区域肺结核发病率与社会经济发展水平的关系。结果:重庆市肺结核高发多集中在东北与东南部地区(Moran’s I指数分别为0.52、0.49、0.50、0.39,P=0.000)。Spearman秩相关分析发现肺结核发病率与人均国内生产总值负相关(r分别为-0.612、-0.611、-0.631、-0.582,P=0.000)。地理加权回归系数变动范围为-4.44~3.20,东北部与东南部影响较大,全市92%的区县肺结核发病率与人均GDP呈负相关。结论:重庆市不同地区经济发展对肺结核发病的影响有差异,有必要制定区域措施防控当地肺结核发病。
Objective：To explore tuberculosis incidence related to social economy vary across 38 counties of Chongqing area. Methods： Spearman rank correlation analysis and geographically weighted regression（GWR） were used to figure out the relationship between tu- berculosisincidence and social economy with four-year tuberculosis and social economic data from 2011 to2014. Results：Incidence of tuberculosis concentrated in the northeast and southeast of Chongqing region（Moran＇s I were 0.52,0.49,0.56,0.39,P=0.000）. In- cidence of tuberculosis was negatively related to per capita GDP by Spearman rank correlation analysis （r were -0.612,-0.611,- 0.631,-0.582 respectively,P=0.000）. GWR.coefficients varied from -4.44 to 3.20. Northeast and southeast areas exhibited high in- fluence on tuberculosis incidence and per capita GDP. Negative correlation distributed in a large area of 92% of the districts/counties. Conclusion：The influence of social economy on tuberculosis incidence varies across regions. Measure related to different regions on tuberculosis prevention and control should be developed.
