Abstract: Objective To understand the awareness of tuberculosis among primary and secondary school students in Jizhou District of Tianjin,and evaluate the effect of special health education. Methods Using stratified cluster sampling method,861 students from 8 primary and secondary schools in urban and rural areas of Jizhou District were selected as health education subjects from April 2020 to March 2022. A survey questionnaire was used to survey 861 students before and after health education,and a total of 826 questionnaires were valid for both surveys. The survey before health education was an awareness rate survey,while the survey after health education was the evaluation of the effect of health education. Results The overall awareness rate of tuberculosis prevention and treatment knowledge before health education was 61.28% and 97.26% after special health education,and the difference was statistically significant（χ²=1 951.621,P<0.01）. Students' awareness of the three aspects of "whether tuberculosis is transmitted at close range","how long to consider tuberculosis after coughing" and "where to see a doctor if you have tuberculosis" had significantly improved,from 62.83%（519/826）,39.95%（330/826）,45.28%（374/826） before intervention to 99.52%（822/826）,90.56%（748/826）,and 99.64%（823/826）,respectively,and the differences were statistically significant（all P<0.01）. Among the students,the proportions of "treating patients with tuberculosis around them as usual" and "very willing to learn about tuberculosis related prevention knowledge" increased significantly,from 16.59%（137/826） and 9.93%（82/826） before the intervention to 77.12%（637/826） and 98.31%（812/826）,respectively,with statistically significant differences（both P<0.01）. Conclusion The awareness rate of tuberculosis among students in Jizhou District of Tianjin is not high,and the awareness rate of students has significantly improved after special health education.Health education in different modes and forms according to the characteristics of students is an effective measure for the prevention and control of tuberculosis.
