Abstract

Objective To investigate the status of latent tuberculosis infection(LTBI)among freshmen in middle schools and their willingness of preventive treatment in Yunyan District of Guiyang, so as to provide a reference for the prevention and control of tuberculosis in schools. Methods The tuberculin skin test (TST) and X-ray scans were used to screen the TB infection of 13 915 freshmen in middle schools in Yunyan District of Guiyang in 2023, and a questionnaire survey on the willingness of accepting tuberculosis preventive treatment was conducted to LTBI patients. The χ² test and Fisher exact probability was conducted for the comparison of the rates among the groups. Results Among the freshmen screened, the detection rate of LTBI was 3.29%. There were statistically significant difference in LTBI rates among freshmen of different genders (boys: 2.87%, girls: 3.81%), age groups (12-15 years old: 3.31%, 16-17 years old: 3.92%, 18-20 years old: 1.91%), and school stages (junior high school: 3.52%, ordinary high school: 5.96%, vocational high school: 2.29%)(χ²=9.59, 13.08, 54.30, P < 0.01). A total of 356 LTBI freshmen completed questionnaire survey, and 299(83.99%) were willing to accept tuberculosis preventive treatment, but the actual number of LIBI freshman who underwent preventive treatment was zero. Those LTBI who had received Bacille Calmette-Guérin(BCG) vaccine(86.97%) was higher in the reporting rates of being willing to accept preventive treatment than that of LTBI who had not received BCG vaccine(75.79%), the differences were statistically significant(χ²=6.48, P < 0.05). The main reasons for refusing preventive treatment was worry about adverse drug reactions(80.70%), social acceptance and the support of social institutions were needed most(85.96%). Conclusion The LTBI rate among freshmen in Yunyan District of GuiYang is higher. Although the freshmen with LTBI have a higher willingness to accept preventive treatment, however, no one has undergone preventive treatment. Corresponding measures need to be taken for improving the preventive treatment rate of LIBI freshmen.
