Effect of chronic exposure to indoor air pollutants on lung function
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 1
Abstract
Background: A significant number of women living in rural areas use biomass fuel like wood, dung or crop residues for cooking. They are exposed to the smoke produced by combustion of these materials, which can cause harmful effects to the respiratory system. Objective: The present study was done to evaluate the effect of chronic exposure to biomass fuel smoke on the lung functions of rural women. Methods: The case control study included 150 female subjects of comparable age group. 75 of them were biomass fuel users and 75 were liquefied petroleum gas (LPG) users. Both the groups had been exposed to the respective fuel during cooking for over 15 years. After detailed questionnaire the Peak expiratory flow rate (PEFR) were assessed by computerized spirometry and statistical comparisons was done by using student t-test. Results: The percentage predicted value of the lung parameters of the biomass fuel users PEFR (p<0.01) were reduced significantly in biomass fuel users as compared to those using LPG. Conclusion: The results of this study suggest that exposure to biomass fuel smoke for chronic period can lead to reduction in lung function.
