To investigate if exposure to firewood smoke and other indoor pollutants is a potential risk factor for obstructive airways disease (OAD) among women in Bogota in whom cigarette smoking and other known risk factors may not be the most frequent.
We conducted a hospital-based case-control study to identify risk factors for OAD among women in Bogota.
An interview was conducted using a modified questionnaire recommended by the American Thoracic Society for epidemiologic studies.
We compared 104 OAD cases with 104 controls matched by hospital and frequency matched by age.
Analysis : The odds ratio (OR) was used as the basic statistic to evaluate risk.
Multivariate analysis (MA) was conducted by the Mantel-Haenszel procedure and by logistic regression.
Univariate analysis showed that tobacco use (OR=2.22 ; p<0.01), wood use for cooking (OR=3.43 ; p<0.001), passive smoking (OR=2.05 ; p=0.01), and gasoline use for cooking (OR=0.52 ; p=0.02) were associated with OAD.
Trends for years of tobacco use and years of wood cooking were present (p<0.05).
After MA, variables remained significant except gasoline use.
This study showed that among elderly women of low socioeconomic status in Bogota, wood-smoke exposure is associated with the development of OAD and may help explain around 50% of all OAD cases.
The role of passive smoking remains to be clarified.
This work may set the basis for intervention...
