Risk factors of tuberculosis : a case control study from Kasetwisai District, Roi-Et

Abstract

Purpose : To study the risk factors for tuberculosis (TB) in Kasetwisai district, Roi Et Province.

Study Design : A case-control study.

Materials and Methods : The study population was divided into two groups: chest X-ray (CXR) confirmed pulmonary TB cases or healthy controls. The sample size of 117 per group was estimated when participants aged 15 years or old were enrolled in the study. Data were collected from patients admitted to the TB clinic between 2020 and 2022 in the cases group, and the patients who visited the outpatient department and had normal CXR in the controls group. Simple and multivariate logistic regression analyses were performed when the risk factors associated with TB were estimated by an adjusted odds ratio (AOR) and 95% confidence intervals (95% CI).

Main findings : Multivariate logistic regression revealed that the reduced body mass index (AOR=0.71, 95%CI; 0.62, 0.82, p<.01), hypertension (AOR=3.26, 95%CI; 1.26,8.42, p=.01) no BCG immunization (AOR=4.72, 95%CI; 18.84, 12.06, p<.01) and family history of TB (AOR= 6.05, 95%CI=1.49, 24.50, p<.01) had an increased risk for TB.

Conclusion and recommendations : The findings of this study high risk factors for TB, Therefore, relevant agencies should screen for new cases as quickly as possible, using those factors to determine screening.
