RESUMO
@#Abstract: Objective To analyze the incidence of pulmonary tuberculosis infection in the elderly(≥ 65 years old) in Xianning City from 2011 to 2021, and to provide scientific basis for formulating strategies and measures for tuberculosis prevention and treatment in the elderly. Methods Descriptive epidemiological analysis was used to analyze the epidemic characteristics and influencing factors of elderly (this article studies elderly people aged 65 and above) pulmonary tuberculosis in Xianning City, Hubei Province from 2011 to 2021. Results From 2011 to 2021, the average annual registration rate of elderly patients with pulmonary tuberculosis in Xianning City, Hubei Province was 211.52/100 000 (5 289/2 500 496), which showed a downward trend （χ2 trend=58.06, P<0.05), and significantly higher than the average registration rate of 96.04/100 000 patients with pulmonary tuberculosis (26 463/27 554 195)(χ2=2 896.69, P<0.05). The average proportion of the registered number of elderly patients with pulmonary tuberculosis in the whole population was 19.99% (5 289/26 463), which showed an upward trend (χ2trend=272.05, P<0.05). The average positive rate of etiology in elderly patients with pulmonary tuberculosis was 51.86% (2 743/5 289), which was significantly higher than that in the whole population 46.41% (12 282/26 463) (χ2=52.53, P<0.05). The average proportion of retreated patients in elderly patients with pulmonary tuberculosis was 8.92% (472/5 289), which was significantly higher than that of retreated patients in the whole population 6.33% (1 674/26 463) (χ2=47.23, P<0.05). The sex ratio of male to female in elderly patients with pulmonary tuberculosis was 2.92∶1. Among the six counties (districts) under the jurisdiction of Xianning City, Hubei Province the registration rate of elderly tuberculosis patients in Xian'an district was the highest 262.20/100 000 (1 267/483 220), and that in Tongcheng County was the lowest 123.83/100 000 (575/464 338), with significant differences (χ2=233.67, P<0.05). Conclusion The overall incidence of tuberculosis in the elderly in Xianning City , Hubei Province showed a downward trend, but the proportion of the incidence of tuberculosis in the elderly in the whole population has increased year by year, suggesting that the elderly are the key population of tuberculosis prevention and control in Xianning City in the future, and comprehensive prevention and control measures should be taken to reduce the incidence of tuberculosis in the elderly population.
