ABSTRACT

Objective To analyze the epidemic characteristics of tuberculosis in Zibo City in recent years, and to provide a scientific basis for the formulation of tuberculosis prevention and control strategies and measures during the 14th Five-Year Plan period. Methods Descriptive epidemiological analysis was used to analyze the information of tuberculosis patients registered in “China Disease Control and Prevention Information System-Tuberculosis Information System” from 2012 to 2020 in Zibo City. Results From 2012 to 2020, a total of 12,706 pulmonary tuberculosis patients were registered in Zibo City, and the registered incidence rate decreased year by year (F=53.348, P<0.001), with an average annual rate of 30.45/10 million. There was no significant change in mortality. In regional distribution, the incidence was higher in northern region of Zibo than that in the southern region, with a cross distribution in the central region. In terms of time distribution, there were cases in each month over the years, and the overall trend increased first, then decreased and once again increased (F=8.856, P=0.006<0.01), with two low points occurring between January to February and also in October, and two peaks occurring between May to June and also in December. In terms of population distribution, most patients were local cases (82.38%). The incidence rate of males was about 2.09 times that of females. The incidence rate of children aged 0-14 was the lowest, while elderly people aged 65 years old and over had the highest incidence (61.02/10 million). Farmers were the main occupation among tuberculosis cases, accounting for 60.59% of the total. The main source of patients was from tracking, accounting for more than 50% since 2016. Conclusion The epidemic of tuberculosis in Zibo is stable and the incidence rate is decreasing year by year, showing seasonal variations. The majority of the patients are male. Special attention should be paid to farmers and the elderly, and further research on risk factors in high-risk areas and counties should be strengthened.
