Abstract:

Objective: To analyze the epidemiological characteristics of pulmonary tuberculosis in Qingdao from 2008 to 2022. Methods: A total of 38507 pulmonary tuberculosis patients registered in Qingdao from January 1, 2008 to December 31, 2022 were collected through the “Disease Surveillance Information System”,and then the epidemic characteristics of pulmonary tuberculosis were analyzed. Results: From 2008 to 2022, 38507 cases of pulmonary were totally reported in Qingdao. The average reported incidence rate was 27.63/100000, with an average annual decline rate of 3%. The highest incidence rate was reported in 2008 (33.66/100000), and the lowest incidence rate was reported in 2022 (20.78/100000). (1) Time distribution: the number of reported cases showed a clear temporal pattern from 2008 to 2019, with a higher number of reported cases from March to August each year, accounting for 55.16% (17539/31798); November and January to February were the lowest reported incidence periods, accounting for 20.46% (6505/31798). (2) Regional distribution: from 2008 to 2022, the average reported incidence rate of active pulmonary tuberculosis was the highest in Licang District (50.09/105, 3622 cases), and the lowest was in Shinan District (20.70/100000, 1719 cases). (3) Population distribution: the reported incidence rate of male was 52.97/100000 (26959 cases), which was higher than that of female (13.05/100000, 11548 cases); the age group of 20-29 years old had the highest proportion of patients (25.81%, 9940/38507), and the proportion of people who work as “farmers” was the highest (40.59%, 15631/38507). Conclusion: The reported incidence of pulmonary tuberculosis in Qingdao showed a decreasing trend from 2008 to 2022. Prevention and control in key areas and populations should be further strengthened.
