Objective: To investigate the health-seeking delay in tuberculosis among school students in Yining City, Xinjiang Uygur Autonomous Region from 2009 to 2020, and analyze the influencing factors, so as to provide the evidence for reducing the health-seeking delay in tuberculosis among students in Yining City. Methods: The demographic features and diagnosis of students with tuberculosis in Yining City from 2009 to 2020 were retrieved from the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System, and the factors affecting the health-seeking delay in tuberculosis were identified using the multivariable logistic regression analysis. Results: A total of 443 students with tuberculosis were reported in Yining City from 2009 to 2020, including 209 boys and 234 girls, with a male/female ratio of 1∶1.12. There were 29 primary school students ( 6.55% ), 81 junior high school students ( 18.28% ), 187 high school students ( 42.21% ) and 146 college students ( 32.96% ) reporting tuberculosis, and 394 cases ( 88.94% ) had locally registered residence. There were 287 students with health-seeking delay in tuberculosis ( 64.79% ), and the median duration of health-seeking delay was 35 ( interquartile range, 33 ) days. Multivariable logistic regression analysis showed that registered residence ( local, OR=1.899, 95%CI: 1.004-3.591 ) and origin of tuberculosis patients ( clinical consultation, OR=3.448, 95%CI: 1.755-6.775; recommendation for symptoms, OR=3.215, 95%CI: 1.161-8.900; tracking, OR=2.415, 95%CI: 1.269-4.596 ) and diagnostic results ( positive sputum smears, OR=3.081, 95%CI: 1.710-5.551 ) statistically correlated with health-seeking delay among students with tuberculosis. Conclusions The proportion of health-seeking delay in tuberculosis was high among students in Yining City from 2009 to 2020; registered residence, origin of tuberculosis patients and diagnostic results were associated.
