Summary

Exposure to biomass smoke from cooking stoves is linked to tuberculosis (TB). This study found a significant association, suggesting biomass smoke may play a causal role in TB development.

Area of Science:

  • Environmental Health
  • Infectious Diseases Epidemiology
  • Respiratory Medicine

Background:

  • Indoor air pollution from biomass fuels is a global health concern.
  • Tuberculosis (TB) remains a leading infectious disease, particularly in low-resource settings.
  • Previous studies have suggested a link between biomass fuel use and respiratory illnesses.

Purpose of the Study:

  • To investigate the association between domestic biomass smoke exposure and tuberculosis.
  • To determine if biomass stove use is a risk factor for developing tuberculosis.

Main Methods:

  • A case-control study was conducted with 288 tuberculosis patients (cases) and 545 patients with other ailments (controls).
  • Exposure to biomass smoke was assessed by self-reported history of cooking with traditional wood stoves.

  • Data were collected from patients at a chest referral hospital, primarily in urban and suburban Mexico.

    • Main Results:

    • Biomass smoke exposure was significantly higher among tuberculosis cases compared to controls.
    • Current exposure to biomass smoke showed a strong association with tuberculosis (OR=5.2).
    • The association was most pronounced in urban areas of Mexico City and central Mexico, with an adjusted OR of 2.4.

    Conclusions:

    • Current domestic biomass smoke exposure is a significant risk factor for tuberculosis.
    • The findings support a potential causal role of biomass smoke in tuberculosis development.
    • Public health interventions targeting indoor air quality may help reduce the burden of tuberculosis.
