Abstract:

Objective: To analyze the temporal trends in pulmonary tuberculosis (PTB) incidence in major Chinese megacities (Beijing, Shanghai, Guangzhou, and Shenzhen) from 2015 to 2024 using Joinpoint regression, providing evidence for the formulation of targeted prevention and control measures. Methods: Data on reported PTB cases in core megacities from 2015 to 2024 were collected; descriptive analysis was used to assess incidence characteristics, and Joinpoint regression was applied to analyze temporal trends. Results: From 2015 to 2024, the average annual reported incidence rates per 100000 population were 30.55 in Beijing, 56.24 in Guangzhou, 24.83 in Shanghai, and 36.68 in Shenzhen. Joinpoint regression analysis revealed that the reported incidence rate in Beijing showed a gradual downward trend from 2015 to 2021 (APC=-4.36%, P=0.070) and a rapid downward trend from 2021 to 2025 (APC=-11.58%, P<0.001); In Guangzhou, the annual average reported incidence rate showed the greatest decline (AAPC=-10.03%, P<0.001), with a rapid decline from 2015 to 2021 (APC=-11.41%, P<0.001) and a gradual decline from 2021 to 2024 (APC=-7.19%, P=0.008). The reported incidence rates among men in the four cities of Beijing, Shanghai, Guangzhou and Shenzhen (38.22 per 100000, 32.30 per 100000, 64.10 per 100000 and 43.82 per 100000) were all higher than those among women (22.34 per 100000, 16.85 per 100000, 33.54 per 100000, 28.09 per 100000). In Beijing and Shanghai, the rate of decline in the reported incidence among men (AAPC=-6.88%, -8.85%) was higher than that among women (AAPC=-6.38%, -7.32%); while in Guangzhou and Shenzhen, the rate of decline in reported incidence among men (AAPC=-9.43%, -5.30%) was slower than that among women (AAPC=-10.36%, -5.98%); The decline in reported incidence rates was greater in the 15-59 age group than in other age groups (AAPC=-9.10%, P<0.001; AAPC=-10.02%, P=0.001; AAPC=-12.06%, P<0.001; AAPC=-9.72%, P=0.003). Conclusion: From 2015 to 2024, the standardized reported incidence rates of pulmonary tuberculosis in the four major core megacities all showed a downward trend, while the etiological positivity rates all showed an upward trend. The standardized reported incidence rate in males was consistently higher than that in females, and the average annual reported incidence rate among the elderly aged 60 years and above was the highest. It is recommended that regionalized periodic screening be implemented for the elderly population, health education in occupational settings be strengthened for young and middle-aged men, and screening strategies be dynamically adjusted based on the smart monitoring systems of megacities, in order to promote a shift in tuberculosis control from passive detection to active intervention.
