Objective: To analyze the delay of seeking medical treatment and associated factors among students with tuberculosis in Shaanxi Province from 2015 to 2019, so as to provide scientific evidence for the early detection and control of tuberculosis epidemics in schools. Methods: Data from 6 739 students with pulmonary tuberculosis registered in Shaanxi Province from 2015 to 2019 were collected from the TB Management Information System of China Information System for Disease Control and Prevention. Univariate and multivariate Logistic regression analyses were used to analyze the characteristics and influencing factors of pulmonary tuberculosis patients. Results: Among 6 739 cases of students with pulmonary tuberculosis from 2015 to 2019 in Shaanxi Province, 3 040 patients delayed seeking medical treatment. The rate of delayed treatment was as high as 45.1%, and the median delayed treatment time was 38(24, 68) days. From 2015 to 2019, the overall delay rate of students showed a downward trend, with a significant difference(χ 2=120.45, P<0.05). Univariate analysis showed that there were statistically significant differences in delay rate between different patient sources, diagnosis results and regions(χ 2=274.19, 26.75, 24.12, P<0.05), among which for factors such as tracing, tuberculosis pleurisy, doctor delay in the northern part of Shaanxi, the rates were higher. The results of multivariate Logistic regression analysis showed that the regions of northern Shaanxi(OR=2.74), central Shaanxi(OR=2.09), and southern Shaanxi(OR=2.39), and clinical consultation(OR=1.84), recommendation(OR=2.81), tracing(OR=3.28), and tracing (OR=6.07) were risk factors for delay of consultation. A lack of etiology results(OR=0.47) was to protect delay of consultation. Conclusion From 2015 to 2019 in Shaanxi Province, a delay in seeking medical treatment was relatively common among students with tuberculosis. The region, source of patients and diagnosis results were factors that influenced the delay in finding tuberculosis patients in Shaanxi Province.
