Introduction:In India, fire rituals (Homa) are commonly performed during religious functions.Some amount of smoke is generated during this ritual. Prolonged exposure to the smoke may lead to lung function abnormalities. However, there is a scarcity of literature on this aspect.
Aims and objectives:To find the spirometricabnormalities if any, in a group of priests who were exposed to smoke during fire ritual, in comparison with normal healthy volunteers
Materials and methods:This was a cross-sectional case control study with 57 cases and 57 controls. Priests who regularly performed fire rituals, at least 3-4 times per month for more than five years were cases. All casesand controls in thisstudy were male respondents. Controls wereage-matched normal, healthy adults without any history of exposure to the fire ritual. In both groups, those with pre-existing lung diseases and smokers were
excluded. FEV1, FVC, FEV1/ FVC Ratio, PEFR, Forced expiratory flow 25 - 75 % were analysed.
Results: Out of 57 cases, 3 cases had obstructive pattern, 11 had restrictive pattern and majority (43) had normal spirometry values. Among control group, 9 had mild restriction. 48 have normal spirometric values, none showed obstructive abnormality.Data was analysed using Independent student T testin Microsoft Office Excel 2007.When each of these spirometry parameters were compared between two groups, the mean difference of FEV-1, FVC, FEV-1/FVC and FEF 25-75 were not statistically significant.
Conclusion: Exposure to smoke generated from fire rituals did not show any lung function abnormality in thisstudy.
