ABSTRACT
Introduction: The effect of body mass index (BMI) on theincidence and prevalence of airway obstructive diseasesasthma, chronic bronchitis, and emphysema—is not clear.The nature of the relationship between BMI and airwayobstructive diseases are also complicated by the potentialeffect respiratory symptoms can have on appetite and physicalactivity. Proposed study was done to find out the associationbetween body mass index and lung functions in males withNon-obstructive airway disease identified by spirometricprotocols.Material and Methods: A retrospective analysis of thespirometry data obtained between August 2018 and January2019 was conducted in the Physiology Department, B. S.Medical College, Bankura for six months. In this study above300 test results over male subjects were taken from studydatabase. Out of those 234 test results of Non-obstructiveairway disease were included considering inclusion andexclusion criteria.Results: The Study shows FVC, FEV1, FEF25-75% PEFR,PIFR, FEF25% and FEF50% have significant positivecorrelation with BMI of underweight. But in normal subject’sonly significant positive correlation between BMI and PIFRwere observed. In overweight there is significant positivecorrelation observed between BMI and PEFR.Conclusion: Our study showed that clear association wasfound between pulmonary function parameters and BMI inmales with non-obstructive airway disease.
