Outline
To explore the status and influencing factors of latent tuberculosis infection among high school students in Chongqing, and to provide technical support for the prevention and control of tuberculosis in schools in Chongqing.
Stratified cluster sampling method was used to select the students of the first and second years of high school in Chongqing in 2023, as the study subjects to detect latent tuberculosis infection with recombinant Mycobacterium tuberculosis fusion protein skin test, to collect the information related to latent tuberculosis infection, and to analyse the influencing factors using Logistic regression model.
A total of 9161 students in the first and second years of high school in Chongqing were included, and 543 latent tuberculosis infections were detected, with a latent tuberculosis infection rate of 5.93%. Multifactorial logistic regression analysis showed that history of previous tuberculosis (OR:4.244, 95%CI:2.239-8.044), history of close contact with tuberculosis (OR:2.096, 95%CI:1.123-3.914), smoking (OR:6.819, 95%CI:3.562-13.053), and staying up late (OR:1.665, 95%CI:1.154-2.402) were risk factors for latent tuberculosis infection in students.
The rate of latent tuberculosis infection among students in the first and second years of high school in Chongqing is low. Not smoking, not staying up late, avoiding close contact with tuberculosis patients, taking good personal protective measures, strengthening physical exercise, and improving immunity can reduce the risk of students being infected with Mycobacterium tuberculosis.
