Abstract:
In China, pulmonary tuberculosis (PTB) screening for children and adolescents is not only focused on family contacts, but also students in high schools. The research objective is to investigate chest X-ray (CXR) abnormalities and its risk factors. From January 2022 to December 2022, PTB screening was conducted among 24,577 Senior 1 and Senior 2 students in Chongqing using the Tuberculin Skin Test (TST) and CXR. The detection rate for suspected PTB through CXR was 0.5% (95% Confidence Interval [CI], 0.3%-0.8%), and the detection rate for PTB through CXR was 0.4% (95% CI, 0.2%-0.6%). Participants in Southeast Districts were more likely to develop PTB (Adjusted Odds Ratio [AOR], 9.6; 95% CI, 1.3-70.4). CXR has played a significant role in PTB screening in high schools in the Chongqing. It is necessary to strengthen policy support for the Southeast Districts in Chongqing.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
