Abstract:

Objective: To provide more targeted pulmonary tuberculosis (PTB) prevention and control policy suggestions by analyzing the spatial-temporal distribution characteristics of PTB notification rate among people aged 60 years and above at county level in Gansu Province from 2018 to 2022. Methods: The number of PTB notification cases and data of resident population disaggregated by county level,gender and age group in Gansu Province from 2018 to 2022 were derived from the Chinese Disease Prevention and Control Information System. Global spatial autocorrelation (Moran’s I) and local spatial autocorrelation were analyzed, so did the spatial-temporal scanning. Results: The average PTB notification rate among males ≥60 years in county level of Gansu Province from 2018 to 2022 was 74.53/100000 (7740/10385100), and for females it was 61.79/100000 (6661/10780200). The notification rate among all elderly people at county level of Gansu Province from 2018 to 2022 showed spatial autocorrelation (Moran’s Is>0,Ps<0.05).High-high incidence areas concentrated in Jiuquan City (Suzhou District,Dunhuang County,Guazhou County,Yumen County,Jinta County),Jiayuguan City,Zhangye City (Ganzhou District,Gaotai County,Minle County,Shandan County,Sunan County),Wuwei City (Liangzhou District,Tianzhu County,Gulang County),Jinchang City (Yongchang County,Jinchuan District).The spatial-temporal scanning showed that the primary gathering areas of PTB notification rate were mainly Jiuquan City (Suzhou District,Jinta County,Aksai County,Dunhuang City),Jiayuguan City,Zhangye City (Ganzhou District,Linze County,Minle County,Shandan County,Sunan County, Gaotai County),Wuwei City (Liangzhou District,Gulang County,Minqin County). The gathering time was from January 1st 2018 to December 31st 2019. Conclusion: The epidemic situation of PTB in people aged 60 years and above at county level of Gansu Province was still severe from 2018 to 2022, and the notification rate of PTB showed an obvious spatial aggregation, the hot spots concentrated in Hexi Corridor (northwest) of Gansu Province.
