title: Chronic obstructive pulmonary disease secondary to household air pollution.
abstract: Approximately 3 billion people around the world cook and heat their homes using solid fuels in open fires and rudimentary stoves, resulting in household air pollution. Household air pollution secondary to indoor combustion of solid fuel is associated with multiple chronic obstructive pulmonary disease (COPD) outcomes. The exposure is associated with both chronic bronchitis and emphysema phenotypes of COPD as well as a distinct form of obstructive airway disease called bronchial anthracofibrosis. COPD from household air pollution differs from COPD from tobacco smoke with respect to its disproportionately greater bronchial involvement, lesser emphysematous change, greater impact on quality of life, and possibly greater oxygen desaturation and pulmonary hypertensive changes. Interventions that decrease exposure to biomass smoke may decrease the risk for incident COPD and attenuate the longitudinal decline in lung function, but more data on exposure-response relationships from well-designed longitudinal studies are needed.
