Abstract

Abstract:

Objective To analyze the spatial epidemiological characteristics of pulmonary tuberculosis in Heze City from 2017 to 2021 at the township level for reference to develop the prevention and control measures for pulmonary tuberculosis. Methods The registration data of tuberculosis patients in Heze City from 2017 to 2021 were collected from the China Disease Prevention and Control Information System, and then the data were imported into ArcGIS software to establish a spatial database. Global and local spatial autocorrelation analysis was conducted to explore the spatial and temporal distribution characteristics and hot spots of tuberculosis incidence. Results In total, 13 007 tuberculosis patients were registered in Heze City from 2017 to 2021, with an annual average registered incidence rate of 29.76/100 000. The number of registered cases in the past years was 3 150, 3 008, 2 695, 2 186 and 1 968, and the incidence rate was 36.53/100 000, 34.43/100 000, 30.75/100 000, 24.88/100 000 and 22.37/100 000, respectively, which showed a downward trend year by year. The top three towns with the highest annual average incidence rate were Huanggang Town (58.04/100 000) and Litianlou Town (54.66/100 000) under administration of Shanxian County and Tianzhong community of Dingtao District (54.05/100 000). In general, the incidence of tuberculosis in Heze City was spatially clustered (Moran's I= 0.161, P<0.05), and there were 7 towns with high-high clustering areas, including Lijinshitang Town in Juancheng County, Sanchunji Town in Dongming County, Guocun Town, Caozhuang Town, Longwangmiao Town, Zhangji Town and Shilou Town in Shanxian County. The incidence hotspots encompassed 10 towns, mainly distributed in Shanxian County in the southeast and Dongming County in the west of Heze City. Conclusion The incidence of tuberculosis in Heze City presents spatially clustered at the township level, and the incidence hotspots are mainly located in the southeast and west of Heze City.
