Abstract

Abstract:

Objective: To analyze the tuberculosis screening results of college freshmen in Sichuan Province in 2023, assess the prevalence of tuberculosis and Mycobacterium tuberculosis (MTB) infection among this population, and provide insights for future tuberculosis screening efforts targeting college freshmen. Methods: Basic information on new students enrolled in Sichuan Province in 2023 was obtained through the student registration management systems of various universities. Tuberculosis Screening Information Forms for freshmen enrolled in the autumn of 2023 were collected, and a database was established. Descriptive statistical analysis was conducted to examine the characteristics of tuberculosis screening, the detection of MTB infection, and other relevant factors among college freshmen. Results: In 2023, a total of 617087 new students were enrolled in ordinary colleges and universities in Sichuan Province, with a tuberculosis screening rate of 99.99% (617025/617087). The overall detection rate of tuberculosis in the province was 18.15/100000 (112/617025). Among Yi students, the detection rate was 136.82/100000 (30/21927), and among Tibetan students, it was 41.57/100000 (5/12029), both of which were significantly higher than the detection rate among Han students (14.16/100000 (74/522703)). This difference was statistically significant (χ²=79.802, P=0.001). The detection rate of MTB infection across the province was 4.01% (24507/611434). Among Yi students, the infection rate was 7.74% (1743/22522), among Tibetan students 5.95% (737/12377), among Qiang students 4.78% (141/2951), and among Hui students 4.16% (90/2164), all significantly higher than the rate among Han students (3.87% (20947/541856)) and other ethnic minority students (2.87% (849/29564)). These differences were statistically significant (χ²=1069.122, P<0.01). The preventive treatment rate for MTB infection among new students was 4.18% (330/7902). Conclusion: The tuberculosis screening rate among college freshmen in Sichuan Province in 2023 was high. However, the detection rate of tuberculosis and the infection rate of MTB were significantly higher among Yi and Tibetan students compared to Han students. The preventive treatment rate for MTB infection remains low.
