Background: Chronic obstructive pulmonary disease (COPD) is the leading cause
of morbidity and mortality worldwide. It is the result of cumulative exposures
over decades. Tobacco smoking, occupational, outdoor, and indoor air pollution
(burning of wood and other biomass fuels) are the major risk factors for COPD.
Objective: The objective of the study was to compare the respiratory symptoms
and lung functions in patients with COPD associated with biomass and tobacco
exposure.
Materials and Methods: We retrospectively evaluated symptoms and
spirometry data of 512 patients who underwent spirometry at the pulmonary function
laboratory of our institute. Clinical data were collected from a standardized respiratory
questionnaire recommended as per American Thoracic Society guidelines. From the
total of 512 patients, we selected 188 patients who had COPD as per gold guidelines.
Results: There was no difference in respiratory symptoms, lung functions, and severity
of disease in biomass and tobacco group (P > 0.05).
Conclusion: Biomass smoke is an important risk factor for COPD. Biomass and tobacco smoke have a similar type of deleterious effect on lung functions.
