Abstract:

Objective To analyze the epidemiological characteristics of the pulmonary tuberculosis in Ji’nan from 2010 to 2019, providing data basis for epidemic prevention and control. Methods The data of pulmonary tuberculosis patients in Ji’nan from 2010 to 2019 were selected from “China Information System for Disease Control and Prevention Infectious Disease Surveillance System”. The annual demographic data of Ji’nan were collected from the “Ji’nan Statistical Yearbook”. Descriptive epidemiological methods were used to analyze the data of the pulmonary tuberculosis surveillance report in Ji’nan from 2010 to 2019, and the main characteristics of the incidence were also summarized. Results From 2010 to 2019, 25495 cases of pulmonary tuberculosis were reported in Ji’nan, with an average annual reported incidence of 36.41/10⁵. The reported incidence decreased from 48.96/10⁵ (3024/6176000) in 2010 to 31.90/10⁵ (2380/7460400) in 2019, showing a downward trend year by year ($X^{2}_{trend}$=371.225, P<0.01). The average annual reported incidences of Tianqiao District (42.97/10⁵, 3001/6984000), Shanghe District (41.65/10⁵, 2489/5976600) and Lixia District (39.74/10⁵, 2959/7445500) were the top three; the number of reported pulmonary tuberculosis cases in Licheng District (4402, 17.27%) was the most in Ji’nan. The annual reported incidence rate of the male was significantly higher than that of the female (47.25/10⁵ (16747/35446400) vs. 25.30/10⁵ (8748/34578200), χ²=2316.435, P<0.01). The male cases mainly aged 15-25 years old (17.22%, 2884/16747) and the 55-65 years old (18.12%, 3034/16747),and of the female cases, 25-35 years old (21.96%, 1921/8748) was the most common age of onset. As to occupation distribution, the farmer was the most (10800, 42.36%), followed by the housework and unemployment (4417, 17.32%), retired personnel (2607, 10.23%), students (2218, 8.70%) and the worker (2114, 8.29%). Conclusion The incidence of pulmonary tuberculosis in Ji’nan showed a downward trend from 2010 to 2019. The pulmonary tuberculosis prevention and control should be enhanced in young adults, farmers and students.
