Abstract:
Objective:To explore the current situation and influencing factors of latent tuberculosis infection (LTBI) among middle school students in Yuhang District, Hangzhou City, so as to provide evidence for optimizing targeted school tuberculosis prevention and control strategies.
Methods:The study targeted students in grades 7 through 11 in Yuhang District from 2023 to 2025. LTBI screening was conducted annually from September to November using the tuberculin skin test. Basic data, such as the year of screening and gender, were collected through the Yuhang District Public Health Emergency Intelligent Control System, while information on school type and boarding status was gathered from the schools themselves. A multivariable logistic regression model was used to analyze the influencing factors for LTBI among middle school students.
Results:A total of 102 092 person-tims middle school students were screened, including 54 015 person-tims of boys (52.91%) and 48 077 person-tims of girls (47.09%). LTBI was detected in 6 913 person-tims, with a detection rate of 6.77%. Multivariable logistic regression analysis showed that screenings conducted in 2024-2025 (2024, OR=1.123, 95%CI: 1.055-1.196; 2025, OR=1.255, 95%CI: 1.181-1.334), girls (OR=1.146, 95%CI: 1.092-1.204), and students in grades 8 through 11 (grade 8, OR=1.707, 95%CI: 1.588-1.836; grade 9, OR=1.634, 95%CI: 1.515-1.762; grade 10, OR=1.713, 95%CI: 1.574-1.864; grade 11, OR=1.691, 95%CI: 1.549-1.846) had a higher risk of LTBI; students in boarding schools (OR=0.619, 95%CI: 0.575-0.666) had a lower risk of LTBI.
Conclusion:The prevalence of LTBI among middle school students in Yuhang District is relatively high, primarily due to the year of screening, gender, grade level, and boarding school.
