| ObjectiveThis study focuses on Geographical distribution pattern with the Geographical autocorrelation analysis of Spatial Epidemiology to identify the hotspot region for the tuberculosis, demonstrates the Geographical pattern and rule of prevalence. Further analysis on the discrepancy of TB patients among mobilized population and local TB patient, to provide scientific evidence for the prevention and control of tuberculosis.MethodAccess to Tuberculosis Management system of the Information System of Chinese Center for Disease Control and Prevention to export the data of registered population and non-resident TB patient in all areas(excludes Taiwan, Hong Kong and Macao), which will be analyzed by Excel and ArcGIS9.3.Result(1) In the year of2010and2011, the proportion of non-resident TB patients among all TB patients is7.95%(74596/938476) and8.13%(73635/905343) respectively. The proportion of non-resident TB patient in Eastern area among all non-resident TB patients is76.12%(56379/74062) and76.21%(56117/73635) respectively. In the west, The number of non-resident TB patient in Xinjiang autonomous region is increased by1.29%[[(1254/24369-1029/26708)×100%] in2011over2010. Tibet is2.77%[(235/3598-128/3403)×100%], Yunnan is1.14%[(1396/24421-1026/22409)×100%](2)Among age groups among non-resident population, the15-year-old age group is highest, which count for27.54%, the age group of15-45year-old account for83.97%of the total; The proportion of female TB patients with non-resident (32.37%)is higher than those with household register(30.35%).In the regard of occupation distribution of registered population TB patient, Farmers and herders rank first, which is up to69.66%and among non-resident TB patient migrant workers ranks first.which is26.81%,second is workers,21.30%.(3)There is an obvious "low-value "clustered in the area of Qinghai, Gansu, Ningxia, Shanxi and the neighboring area, which means the number of cases is low; The "high-value "clustered in the area of Hunan, Hubei, Chongqing, Guangdong, Fujian and surrounding area, the number is high.In Shanghai, Zhejiang, Guangdong, Fujian and neighboring areas, the number of no-household register is comparatively high, whereas, the number of the registered is only higher in the locality in Beijing and Chongqing.(4) Sichuan province exports the most cases which direct to Zhejiang, Jiangsu, Fujian, Shanghai and Guangdong; The source of patients in Beijing, Tianjin, Shanghai, Guangdong, Jiangsu, Zhejiang and Fujian comes from other provinces.Conclusionnon-resident TB patient cluster around the eastern coast area;Most TB Patient among non-resident are young adults, peasants and herdsman are the most attacked population;Western and middle area export most mobilized population. The main source of TB patients among non-resident population is Sichuan, Guizhou, Anhui, Hunan and Henan, which account for a large proportion of non-resident TB patients in high economic settings.Recommendations(1) Increase of tuberculosis prevention and control work of non-resident population in the eastern region, at the same time, more attention should be paid to the floating population tuberculosis prevention and control work in the western region.(2) strengthening the health consciousness of health knowledge propaganda and education of the non-resident population.(3) Carry out pre-employment physical examination and symptoms screening.(4) According to the population flow characteristics of different provinces formulate to accord with the province of the non-resident population health insurance policy. |
