ABSTRACT

Introduction: Exposure to wood smoke and tobacco smoke at home affect especially children, due to the immaturity of their respiratory and immune system, so you have a higher risk of developing pulmonary tuberculosis (TB). Objective: To determine whether there is an association between exposure to wood smoke and the risk of developing respiratory TB bacteriologically confirmed in children aged ≤17 years, non-smokers.Material and methods: We conducted a case-control study retrospective, hospital-based, non-matched, from 2000-2010. (Approval Number C07- 03). Cases were patients with confirmed TB patients and controls otolaryngology (ENT). The host risk factors, housing and the environment were obtained from institutional databases. Analysis was used unconditional logistic regression. Results: We included 28 children with TB and 337 controls ENT. In multivariate analysis, exposure to wood smoke was associated with an increased risk of TB (OR = 3.2 [95% CI 1.3-9.9], p = 0.01), after controlling for confounding factors. Conclusions: Exposure to wood smoke is associated with the development of TB in children. In our study, passive smoking was not associated with development of TB.
