Abstract:

Objective: To analyze global development trends and hotspots of researches on elderly tuberculosis from 2000 to 2025 using bibliometric methods, aiming to provide references for future research and prevention strategies. Methods: Literature with topics of “tuberculosis” and “elderly” published between January 1, 2000, and March 10, 2025, was retrieved from the Web of Science Core Collection. A total of 4103 publications were identified, limited to “Article” and “Review” categories. VOSviewer 1.6.18, CiteSpace 6.1.R6, and Bibliometrix were applied to visualize publication output, distributions of country/region and institution, authors, journals, and keywords. Research hotspots and frontiers were further identified through burst keyword detection. Results: The annual number of publications on elderly tuberculosis increased from 50 in 2000 to 350 in 2024, showing a continuous upward trend, with an average annual growth rate of approximately 8.9%. The publications involved 167 countries/regions and 1442 journals. The top five productive countries were the United States (996), China (598), the United Kingdom (400), South Africa (332), and India (319), accounting for 64.3% of the total output. Highly productive institutions included the London School of Hygiene & Tropical Medicine (94), the University of Cape Town (91), and the University of the Witwatersrand (80). Keyword co-occurrence analysis revealed that research hotspots focused on the epidemiological characteristics of elderly tuberculosis, HIV co-infection and immunosenescence mechanisms, diagnostic technologies, and treatment optimization, with “immunosenescence” emerging as a recent research frontier. Conclusion: Research on elderly tuberculosis has remained active, but international collaboration and cross-disciplinary integration require further strengthening. Future studies should focus on immunosenescence mechanisms, rapid diagnostic techniques, and individualized prevention strategies to improve tuberculosis control among the elderly.
