Abstract:
Objective:To investigate the prevalence and influencing factors of latent tuberculosis infection (LTBI) among freshmen in a vocational college in Xinjiang Uygur Autonomous Region, so as to provide insights into tuberculosis control in vocational colleges.
Methods :All freshmen enrolled in a vocational college in Xinjiang Uygur Autonomous Region in 2020 were recruited and participants' demographics, life style, history of tuberculosis contacts, frequency of ventilation and disinfection in dormitories and classrooms and awareness of core tuberculosis control knowledge were collected through questionnaire surveys. LTBI was detected among freshmen by means of purified protein derivative test (PPD skin test) and chest X-ray scans, and the factors affecting LTBI were identified using a multivariable logistic regression model.
Results:A total of 5 463 freshmen were screened for LTBI, with a screening rate of 100.00%, and the participants included 2 151 men and 3 312 women, with a male/female ratio of 0.65︰1, and had a mean age of (16.83±1.05) years. A total of 388 freshmen were detected with LTBI, with a detection rate of 7.10%, and no active pulmonary tuberculosis was detected. The prevalence of LTBI was 9.44% in men and 5.59% in women. Multivariable logistic regression analysis identified males (OR=1.587, 95%CI: 1.281-1.965), smoking (OR=2.108, 95%CI: 1.355-3.278) and a history of tuberculosis of families (OR=2.851, 95%CI: 1.615-5.034) as risk factors for LTBI among freshmen, and knowing core tuberculosis control knowledge as a protective factor of LTBI among freshmen (OR=0.276, 95%CI: 0.218-0.350).
Conclusions:The risk of LTBI was associated with gender, smoking, history of tuberculosis of families and understanding of the core tuberculosis control knowledge among freshmen in this vocational college in Xinjiang Uygur Autonomous Region. Health education about the core tuberculosis control knowledge is recommended to be reinforced among students in vocational colleges in Xinjiang Uygur Autonomous Region.
