肺结核中国地域分布差异及社会自然因素影响的研究

Study on Geographic Variation and Social-natural Influencing Factors of Distribution of Pulmonary Tuberculosis in China

目的探讨中国各省市肺结核的地域分布差异及社会自然因素的影响。方法收集2008年中国各省市肺结核报告发病率及其可疑影响因素资料，并应用主成分回归探讨它们之间的关系。结果（1）2008年中国各省市肺结核报告发病率不尽相同。（2）随着经度、人均地区生产总值（元）、人均住宅建筑面积（平方米）、每千人口医疗机构床位（张）、各地区每千人口卫生技术人员、年平均风速（米，秒）和年降水量（mm）等因素的增高，各省市肺结核的报告发病率有降低趋势。（3）随着纬度、年平均气压（百帕）、年平均气温（摄氏度）和年平均相埘湿度（百分率）等因素的增大，各省市肺结核报告发病率有升高的趋势。结论影响我国各省市肺结核发病率分布差异的因素是多方面的，应进一步开展相关研究。

Objective To study the geographic variation and social-natural influencing factors of the distribution of pulmonary tuberculosis in China. Methods The data of the reporting incidence rates of pulmonary tuberculosis in different provinces and influencing factors in 2008 were collected. The relationship between the reporting incidence rates of pulmonary tuberculosis and influencing factors were analyzed by principal component regression. Results （1） The reporting incidence rates of pulmonary tuberculosis were different among the provinces of China in 2008. （2） With the increasing of longitude, GDP per capita （yuan）, per capita residential area （square meters）, medical institutions beds/1000 population, health personnel number/1000 population, average annual wind speed （m/s） and annual precipitation （mm） in 2008, the reporting incidence rates of pulmonary tuberculosis decreased. （3） As the increasing of latitude, average annual air pressure （hPa）, average annual temperatures （~C） and average annual relative humidity （percentage） accordingly, the reporting incidence of pulmonary tuberculosis increased. Conclusions The differences of the incidence rate of pulmonary tuberculosis were impacted by many factors among provinces in China, a further study should be taken.
